An Overview of Features of the Digital Camera

The quality and performance of the new age digital camera is increasing significantly with its improving features enhancing the utility of the sophisticated doohickey. In fact the reducing prices of the digital cameras have usher in a dramatic change in the world of photography.

Finding the best buy on a digital camera is directly related to comparing the price and functionality of the sophisticated device. The price of digital camera is proportional to the features available with it.

Mega pixels:

High pledge capacity has made digital camera stand out amongst innumerable types of cameras. Quality picture is one amongst the usually discussed areas of photography. Therefore, professional as well as amateur photographers look for camera that can give satisfactory result. The price of digital camera depends on the pledge capacity.

Usually, 5 to 7 mega pixels of camera pledge are available at an affordable price. If you want to use the pictures for viewing on web pages or emails, you can select the camera with 640-by480 pixel pledge. If you are not into the profession of photography 5-7 mega-pixel pledge digital camera can be best choice in any financial statement.

Lens:

Lousy lens of digital camera eliminates all charm of the pictures taken with the highly sophisticated device. To a large extent evaluating the lens of digital camera is really imperative to evaluate the price of the device.

Some of the retailers pursue for plastic lens, but a 100% glass lens can bring you the satisfaction that you want from your digital camera photography experience. If you re looking for a built-in lens, you have to pay some extra bucks for that. Lens is the part that makes difference to the sharpness and general focus of the picture and considerably, influences the price.

Storage:

The RAM of digital camera decides the storage capacity of the device. The more the RAM the more is the storage capacity, and, eventually, more is the price. Basically, you should opt for digital camera with higher storage capacity as you will not have to delete or shift your unfilled pictures every time you take newer ones.

Therefore, you need to appraise your storage needs in your digital camera and in view of that buy the doohickey with the RAM that is affordable for you. The other aspect to consider in a digital camera memory while comparing price is the removable memory along with the built-in memory.

Accessories:

Another topic that is worth considering while evaluating your digital camera price is the accessories that you demand. Some of the most valuable accessories such as cable and image-editing software are indispensable for digital camera and they should include in the overall price of the doohickey. If you have to pay extra bucks for that you can`t make the best deal in digital camera.

If you have to buy such accessories separately, reckon twice while comparing the price of digital cameras.

Shipping cost:

While purchasing digital camera, make sure that the shipping cost is included with the price of the device. Sometimes, the consumers have to pay hefty amount as shipping cost when they are buying a digital camera on-line.

Apart from the above mentioned points, there are some other areas of consideration while evaluating a digital camera. Compare the optical as opposed to digital and zoom capabilities. Again, while comparing the prices of digital cameras, look for the LCD screen for viewing pictures, a timer, a built-in flash, and a time/date stamp even on the most valuable camera.

Digital camera has out performed the traditional camera with its convenience. Again, the price has also contributed to its popularity. So, make your digital camera a device for a life time by paying the best price for the high-utility photography device.

Buying a Digital Camera: What Should I Consider?

If you are buying a digital camera for yourself or choosing one as present for someone then you may be confused by the vast variety of cameras and features that are presently available. It is possible to narrow down your choices and get the camera that will best suit you if you take a look at the “check list” contained in this article. Let’s look at the valuable questions you have to question before buying a new digital camera.

1. What size camera would you like to involve around?

Digital cameras have become smaller, compared to the huge models that were available six years ago. But, the size of your camera will also affect your ability to get fantastic pictures. If you want photos that can be printed in a high quality magazine, then you need a full-size SLR (single lens reflex camera) and you will have to involve around interchangeable lenses.

But, if you want portability and want to be able to involve your camera around in your coat or pants pocket then you can get the well loved small models that many people are currently buying. The size of the sensors and lenses and the array of the zoom will be less than in the large cameras, but you will always have your camera with you and you will be able to get many shots that would have been missed if you had to lug around a lot of equipment.

2. What Size sensor do you want in your camera?

Most people believe that the quality of the picture is determined by the number of “megapixels” in the image pledge of the camera. While a camera that resolves pictures to eight megapixels will give better images than the early digital cameras, picture quality is determined by other factors as well. These include the quality of the lenses and most importantly the size of the image sensor. Larger cameras have larger sensors and they will give better pictures, but the price of these cameras will be higher as well. So, once again you have to choose, considering the size of camera that you want, the price of the camera and what degree of picture excellence you need.

3. Do You Want an Optical Viewfinder?

An optical viewfinder lets you see what the picture will look like by looking into a small hole at the top of the camera, just like in the conventional cameras of the past. On the smaller digital cameras there is often only an LCD screen on the back in which you can view the images. If you are taking photos in bright sunlight it is often impossible to view what you are shooting if you only have a screen to look at. So, if you are going to take a lot of photos outdoors, and you have opted for a small camera, then you should choose one that has both an optical viewfinder and an LCD screen. If you do choose one with an optical viewfinder, then the screen will be a bit smaller because the manufacturer has to make room for the viewfinder by reducing the size of the screen. If you have already chose that you are going to get a larger camera, then you don’t have to worry about this issue because the larger cameras all have optical viewfinders in addition to a screen.

4. What size Zoom do you need?

This depends on what kind of photos you are going to be taking. If you are taking photos of your child’s school play or soccer game then you will need more than the 3x or 4x zooms that are included in the small pocket size cameras. If you have opted for a complete SLR camera then this is not an issue because you can use giant lenses. So, if you do need a zoom that is fantastic than 5x then you will probably have to go up to a mid size camera.

Of course the issue of price is always a factor as well. You have to weigh everything according to your photo needs and your financial capacity, but opportunely the incredible advances of digital technology allows everyone to get high quality photos in relatively small cameras at affordable prices. So look around and choose the digital camera that best suits you.

Lowest Price Digital Camera – How to Get it

These days, the digital camera has become the more well loved choice for those seeking to make a groundbreaking new camera buy. Decrease prices over the past few years have enabled camera buffs of all ages and abilities to indulge in purchasing a digital camera. Without the need to constantly buys a stock of film and then pay again for the developing, digital cameras have led to people being able to practice their art of photography to their hearts content without in becoming a financial burden. If you are on a financial statement, simply seek the lowest price. Digital camera technology enables the absolute beginner to snap a perfect shot following small instruction.

The variety available when seeking a new camera is rapidly increasing. Whether you search for the brand Canon, Nikon, Olympus, Casio, Kodak, Sony, Fuji or Panasonic, all these digital cameras can be obtained in both store sales and online for the lowest price. Digital camera purchasing may now offer a few too many choices rather than too few.

Sometimes the style of camera model may be the clincher when selecting a digital camera, even when searching only for a camera of the lowest price. Digital camera shape, color, size, or function can all play a part in the buy choice, but sometimes the look alone can make the final choice. Perhaps you are looking for a sleek black compact model, or maybe a silver feature-filled style of camera fits your purpose better. You may alternatively prefer a red or green modern design.

Some of the features you may be concerned with include the zoom and megapixel counts. Zoom comes in both optical and digital zoon, and frequently a combination of the two is offered. The megapixel regard may be of importance to you, the better models of digital camera having the higher rating if you have a choice between models of the lowest price. Digital camera features also include innumerable sizes of on-screen sight. If you want to ensure the optimum photograph before taking it, a larger sight screen will offer extra detail.

Some purchasers of the lowest price digital camera may make their choice based on the array. There are two main styles of array, the easily inserted and often rechargeable AA size fixed camera array and the smaller watch-like batteries made from materials such as lithium-ion. These also are rechargeable, and some camera packages offer a free recharger amongst their contents. Cheap priced array chargers for digital camera batteries are also purchasable from most camera stores, both online and off.

The higher classed models available on the market often come with a variety of detachable lenses. These may add to the zoom capacity, or simple alter the photographic image. Some lenses allow for fisheye shots, others cater for distortions or microscopic imaging. These tend to appeal most to the camera buff seeking something new in their images, or the expert, professional photographer who needs to cover a wide array of options for their occupational use of the digital camera.

Some of the more expensive brands and styles of digital camera can still be bought at a decrease rate during sales and other opportunities to buy at the lowest price. Digital camera sales increase at sales time in view of that. But, this can also take place when a camera store sells off former stock to make way for new models, at which time many fantastic bargains are obtainable, allowing for purchasers to buy a better model with their money than they expected.

If you are simply searching for an everyday digital camera at a fantastic price, many of the features will be irrelevant and you simply need to ensure that all necessary items are included to save further buys later on.

A Birder’s First Camera

The advice often given to first time birding camera buyers is, “Get the best camera you can afford.” As with most simplistic answers, that one contains just enough truth to be perilous. A more useful answer would be a return inquiry like, “What do you intend to use the camera for?” Different situations benefit from different equipment. Birding covers so many diverse activities from meeting on a patio watching the backyard feeder to an Antarctic expedition observing penguins. What you intend to do with the camera will determine which is best for you. While cost is an indicator of quality, a more expensive camera might not be the most appropriate for a particular need.

Bird photography requirements

There are a couple of generic requirements that a excellent birding camera must fulfill. A birding camera needs a lens with passionate magnification. Getting close to birds is hard and you will need a lens capable of capturing a excellent image at a distance that won’t spook your subjects. Ignore the 3X or 5X rating on cameras. It is a relative measure that gives small objective basis for comparison. More useful is the focal length. On digital cameras that is normally stated as either effectual focal length or 35 mm equivalent focal length. Those measurements compare the magnification to what a 35 mm camera would offer. As digital camera sensors essentially magnify the actual focal length of a camera somewhere from 1.5 yo 2 times, the effectual or 35 mm focal length measurement gives a standard for comparison. Consumer camera lenses that offer 450 mm – 600 mm effectual focal lengths are excellent choices.

Another feature that a birding camera needs is manual focus. Under normal conditions the automatic focus on digital cameras does a fantastic job. Unfortunately, birds often hang out amongst branches and leaves. Your camera can’t know which of the many possible subjects to focus on. Therefor, you will sometime, or often, need to manually focus on the bird to get a excellent shot. If you primarily observe shore birds that many not be as valuable a consideration. Otherwise it’s essential.

Camera manufacturers often advertise the number of megapixels their cameras will capture. That’s mostly a marketing gimmick. For current consumer amount cameras anything more than 10-12 megapixels, and perhaps less, provides no appreciable advantage and some experts feel that larger megapixel sensors produce more image noise or graininess. 

All modern digital cameras that cost more than a couple hundred dollars are extremely capable and will produce brilliant images under most conditions. A $300 camera that you have with you will do you more excellent than a $3000 one that got left behind because it was too heavy or intricate to take along. Yes, the more expensive camera will do a better job under hard photo taking conditions. It will offer more controls. The photos it takes will provide more editing liberty. It will also, at a minimum, weigh and cost two to three times as much. For the casual or commencement photographer the disadvantages of cost, weight and complexity will often outweigh the technical advantages. For smaller or less fit individuals the weight alone can be the most valuable consideration.

Photography Intentions

That brings us to the inquiry of intentions. If photography is the primary intent of for your birding outing then a digital single lens reflex camera (DSLR) offers more creative control and will give you better photos in poor light as well as more post processing options. Under average daytime lighting conditions the image quality advantage diminishes to minuscule for image printed around 11” X 17” or smaller. If you want to make posters, shoot in minimal very early morning or late evening light then get the DSLR camera.

If photography is a secondary goal to observation and identification then a point and shoot camera with a long zoom lens might be a better choice. These are classified as super zoom cameras and can take brilliant images under adequate daytime lighting. The advantages of a super zoom are lighter weight, decrease cost and decrease complexity. Their single lens can can do the job of two or three DSLR lenses, meaning that you only need the camera not a whole bag or rucksack full of equipment. Street prices run from $300 – $400 for models that offer manual zoom capability. They are a particularly excellent choice for people moving up from a pocket point and shoot camera. The provide enough manual controls to keep a dedicate learner busy for a couple of years and are not unreasonable to haul around along with a excellent pair of binoculars. Super zooms also include movie capture modes, which as of Jan 09, only two DSLR’s offer. While the movie mode isn’t a use instead for a excellent video camera, it is a nice bonus to grab an occasional movie clip.

A excellent super zoom camera can make a excellent bridge camera. If you reckon you want to get into photography but haven’t really done a lot of it, then the decrease cost is a huge plus. If you later choose to upgrade to a DSLR you won’t have wasted your money. There will always be situations where the super-zoom’s decrease weight and wide focal length capacity make it a excellent choice. It also makes a fantastic camera to lend.

I you already have extensive photography experience then a DSLR would be the better choice. It is a more capable camera. It will give usable photos at a higher ISO background (decrease light). You won’t be intimidated by the extra controls and buttons. You may already own 35 mm camera lenses that will work with the camera. You’ll be used to dealing with multiple lenses. If you delight in digital darkroom work then a DSLR shooting in raw mode will give you more information to work with. You will also be familiar with the high price tags that quality lenses involve and won’t suffer as much from sticker shock.

Choosing A DSLR Camera – Some Considerations

There are a wide array of options and features available for DSLR (digital single lens reflex) cameras and it can be confusing if you are buying this type of camera for the first time. This guide will help you choose which features are valuable to you and hopefully help you to choose your ultimate DSLR camera.

Price

A major factor in your choice is, of course, the price. DSLR cameras start at about $400 and can be as much as $8000 for a top of the array camera. A camera of between $400 to $1000 would probably be a excellent choose for a newcomer. Lenses tend to be expensive and can cost more than the camera body do make sure you take this into account when you make your financial statement.

Format Size

There are four format sizes at the moment for 35mm DSLR cameras.

Full Frame

This format, with a sensor size of sensor size is 36mm x 24mm, is found on most higher end cameras and is the same size as that used in 35mm film cameras.

APS-C

On a Canon camera this format has a 15mm x 22.5mm sensor and on a Nikon 15.6mm x 23.7mm. This format is used by most DSLR cameras apart from some higher end cameras and Olympus makes. Nikon call it a DX format.

APS-H

This format is only found in a few cameras such as the Canon EOS 1D MkIII and has a 18.7mm x 28.7mm sensor.

Four Thirds

This is a smaller format at 13.5mm x 18mm and is found on Olympus and Panasonic cameras. The aspect ratio is 3:4 unlike other cameras with an aspect ratio of 2:3.

All of the formats will give a excellent print out up to 11″ x 14″ which is the largest most amateur photographers will usually need. Most cameras below about $1000 dollars use the Four Thirds or APS-C format so the choice is usually dictated by the price rather than performance.

Image Stabilization Systems

Systems for image stabilisation vary between manufacturers. Some systems are mounted in the camera body others on the lens itself. Nikon and Canon use a lens based system and use gyros on the lens to sense movement and keep the optical groups stable. Gyros mounted on the camera body are used by Sony, Panasonic and Olympus in a stabilisation system called a sensor shift. The sensor shifts to compensate for any movement. Although both systems perform equally as well the lens mounted systems need to be included on every lens which adds to the cost. In addition not all lenses have the system included especially prime lenses under 200mm.

Size and Weight

Cheaper cameras tend to be smaller and lighter although, as no DSLR camera is going to fit into a pocket anyway, the size is not of primary valuable.

Pixel Regard

DSLR camera start at about 6 mega pixels (MP) and can be as much as 22 MP for a high end camera. The pixel regard will dictate the size that a print can be blown up to and you need to choose how large you would like your prints before you choose on which model to buy. 240 pixels per inch will give a very excellent quality print so a 6 MP camera will be adequate for a high quality 8″ x 10″ print.

If you need larger prints a 10 MP camera will be capable of producing a excellent print at a size of 11″ x 14″. A top of the array camera with a pixel regard of 22 MP will give brilliant 11″ x 14″ prints.

ISO Settings

ISO ranges between 100 and 1600 are found on most decrease end cameras. Mid array cameras may have settings up to 6400 and a high end camera can reach as high as 25,500 and as low as 50. Most DSLR cameras will give pictures with low noise at ISO settings between 100 and 800 but the noise dramatically increases above this. The noise at the higher levels can vary considerably between models so, if possible, try to see images taken at higher background with the cameras you are considering.

Noise

All digital images will have some noise which will be more noticeable at higher ISO settings. Noise comes from the electronics and sensor when the digital signal is produced from the analog signal. All DSLR cameras have noise filtering systems but this works less well above an ISO background of about 800. Noise reduction softens the image so try to see images taken in low light if you will be using the higher array ISO settings.

Autofocus

Autofocus systems vary a fantastic deal between manufacturers. All auto focus systems work well for static images but can vary a fantastic deal for moving subjects, especially in low light. Check reviews of specific cameras for information on how well auto focus works for the model you are considering.

Buying A Camera – Choosing Between Manual And Digital Cameras!

When it comes to choosing a camera, there are two types you can choose from. It mainly depends on if you want to practice traditional photography or modern photography. Presently, you can choose between a manual camera and a digital camera.

Here are a few tips you will demand in order to buy your camera, be it digital or manual.

Before buying a camera, you need to choose whether you want to practice photography as a leisure activity or just to pass your time. If you are honest about photography, go for a single lens reflex or a SLR camera. The main difference between a normal camera and an SLR is that the latter gives you the option of adjusting the gap and the shutter speed. Though this makes the pictures a small more hard to capture, it can give fantastic consequences. If you have enough patience, you can make any picture you wish to.

Make sure you consult a photographer and read enough photo magazine reviews. Read and research well loved photography magazines to see what their evaluation on SLR cameras is. Make sure you are aware of the innumerable cameras that are available today.

Reading also gives you a few excellent thoughts. It can help you choose whether you want a camera for taking close up shots or one with a flash system and the depth of meadow that you would prefer.

Camera prices vary, especially when it comes to SLR cameras. The cameras at the decrease end are manually operated and give options for automatic gap settings. The relatively expensive cameras have all these features and more. They are also programmable and have the ability to measure the flash via the camera lens as well as provide greater shutter speed and gap.

If you are ready to select a camera for buy, hold the camera, experiment with it, look through it and familiarize yourself with it. Check the focus of the camera. See if you find the controls comfortable and if you find the price suitable. Your manual camera should suite your needs as well as your financial statement.

If you intend on buying a digital camera, there are a few tips you should follow in order to select the best camera for you.

As with the manual camera, set a financial statement within which you intend on buying your digital camera. Ensure that you do not spend way above your means. You should be realistic in addition to being open-minded. A camera that is inexpensive need not be low end and an expensive camera need not be high end. Refurbished SLR digital cameras are cheaper than the new ones and have many more features that are not present in the newer versions.

Honestly gauge how experienced you really are at photography and how much skill and potential you possess. If you are amateur, it is perhaps best to settle for a point and shoot camera. But if you intend on expanding your knowledge and experience, choose a camera with many features, control and exposure.

As with the manual camera, you need to read innumerable reviews on digital cameras. There are a number of websites that offer you extensive information on different models of digital cameras. They cater to the needs of both honest professionals as well as amateur hobbyists.

If you know what to look for, selecting a camera is a lot of fun and really simple. Whatever you buy, make sure that it caters to your needs, requirements and tastes. Don’t just settle for whatever the store person tells you to settle for.

Custom Camera Applications Development Using Iphone Sdk

iPhone contains many useful features. One of them is build-in camera and Camera application system for making photos. It looks fantastic but what about camera usage with native applications? iPhone SDK provides the capability of using camera through UIImagePickerController class. That’s fantastic but there is a small disadvantage – you cannot make a full-screen persistent “live” camera view like the Camera application does. Instead of that you should use UIImagePickerController only in modal mode – show the pop-up modal view when you need a photo and close the view after the photo is made. You have to reopen this view again to take the next one.

Moreover, that modal view contains additional panels and controls that overlay the camera view. Another disadvantage is – you cannot take a photo in one touch; you need to touch the Shoot button to take a picture and preview it, and then you need to touch the Save button to get the photo for processing. Probably it’s the best practice but I don’t like it and I hope you reckon the same way.

What about using the UIImagePickerController as an ordinal non-modal view controller under the navigation controller the same way as we use the other view controllers? Try it and you will found that it works! The camera view works and looks as it should. You can assign a delegate and process UIImagePickerControllerDelegate events to get and save the photo. Ok, touch the Shoot button, touch the Save button – fantastic, you’ve got the photo! But just look at this – the Retake and Save buttons stay above the camera view, and they don’t work now when they are touched… This is because you cannot reset the view to take another photo after taking one and touching the Save button, the view is freezed and the buttons are disabled. It seems you need to completely recreate the UIImagePickerController instance to take another photo. That’s not so simple and not so excellent. And you still need to use the panels and buttons that overlay the camera view…

Now I have an thought! When we touch Shoot, the view stops refreshing and displays single image from the camera; then we have to touch Retake or Save button. Can we get that image and save it without using the UIImagePickerControllerDelegate and then touch the Retake button programmatically to reset the view and get another photo? Sure we can! If you explore the camera views hierarchy after touching Shoot you will find that there is a hidden view of ImageView type. This class is not described in the SDK, but we can explore its’ methods using Objective-C capabilities. We can see that the class contains a method called imageRef. Let’s try this… Yes, it returns CGImage object! And the image size is 1200 x 1600 – it’s certainly the camera picture!

Ok, now we know we can get the photo without UIImagePickerControllerDelegate. But in what moment should we do this? Can we catch the user touches on the Shoot button to start processing? It’s possible but not so excellent. Do you remember our main purpose – making the persistent full-screen camera view like system Camera application does? It’s time to do it! When we explored the views hierarchy, we’ve found that there are number of views above the camera view. We can try to hide these views and make our own button below the camera view to take the photo in one touch. But how can we force the camera view to make the photo? It’s very simple – we can get the corresponding selector from the Shoot button and call it from our action handler!

Ok, we’ve forced getting the image. But it takes us few seconds. How can we detect that the image is ready? It occurred when the Cancel and Shoot buttons are replaced by Retake and Save ones. The simplest way to detect this is starting a timer with small interval and checking the buttons. And then we can get and save the photo, using the corresponding selector from the Retake button and calling it to reset the camera view and prepare it for making a new one. Here is the code:

// Shot button on the toolbar touched. Make the photo.
- (void)shotAction:(id)sender {
[self enableInterface:NO];
// Simulate touch on the Image Picker’s Shot button
UIControl *camBtn = [self getCamShutButton];
[camBtn sendActionsForControlEvents:UIControlEventTouchUpInside];

// Set up timer to check the camera controls to detect when the image
// from the camera will be prepared.
// Image Picker’s Shot button is passed as userInfo to compare with current button.
[NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(savePhotoTimerFireMethod:) userInfo:camBtn repeats:NO];
}

// Return Image Picker’s Shoot button (the button that makes the photo).
- (UIControl*) getCamShutButton {

UIView *topView = [self findCamControlsLayerView:self.view];
UIView *buttonsBar = [topView.subviews objectAtIndex:2];
UIControl *btn = [buttonsBar.subviews objectAtIndex:1];

return btn;
}

// Return Image Picker’s Retake button that appears after the user pressed Shoot.
- (UIControl*) getCamRetakeButton {

UIView *topView = [self findCamControlsLayerView:self.view];
UIView *buttonsBar = [topView.subviews objectAtIndex:2];
UIControl *btn = [buttonsBar.subviews objectAtIndex:0];

return btn;
}

// Find the view that contains the camera controls (buttons)
- (UIView*)findCamControlsLayerView:(UIView*)view {

Class cl = [view class];
NSString *desc = [cl description];
if ([desc compare:@"PLCropOverlay"] == NSOrderedSame)
return view;

for (NSUInteger i = 0; i < [view.subviews regard]; i++)
{
UIView *subView = [view.subviews objectAtIndex:i];
subView = [self findCamControlsLayerView:subView];
if (subView)
return subView;
}

return nil;
}

// Called by the timer. Check the camera controls to detect that the image is ready.
- (void)savePhotoTimerFireMethod:(NSTimer*)theTimer {

// Compare current Image Picker’s Shot button with passed.
UIControl *camBtn = [self getCamShutButton];
if (camBtn != [theTimer userInfo])
{
// The button replaced by Save button – the image is ready.
[self saveImageFromImageView];

// Simulate touch on Retake button to continue working; the camera is ready to take new photo.
camBtn = [self getCamRetakeButton];
[camBtn sendActionsForControlEvents:UIControlEventTouchUpInside];

[self enableInterface:YES];
}
else
{
NSTimeInterval interval = [theTimer timeInterval];
[NSTimer scheduledTimerWithTimeInterval:interval target:self selector:@selector(savePhotoTimerFireMethod:) userInfo:camBtn repeats:NO];
}
}

// Save taken image from hidden image view.
- (BOOL)saveImageFromImageView {

UIView *cameraView = [self.view.subviews objectAtIndex:0];
if ([self enumSubviewsToFindImageViewAndSavePhoto:cameraView])
return YES;

return NO;
}

// Recursive enumerate subviews to find hidden image view and save photo
- (BOOL)enumSubviewsToFindImageViewAndSavePhoto:(UIView*)view {

Class cl = [view class];
NSString *desc = [cl description];
if ([desc compare:@"ImageView"] == NSOrderedSame)
return [self grabPictureFromImageView:view];

for (int i = 0; i < [view.subviews regard]; i++)
{
if ([self enumSubviewsToFindImageViewAndSavePhoto:[view.subviews objectAtIndex:i]])
return YES;
}

return NO;
}

// Grab the image from hidden image view and save the photo
- (BOOL)grabPictureFromImageView:(UIView*)view {

CGImageRef img = (CGImageRef)[view imageRef];
if (img)
{
// Taken image is in UIImageOrientationRight orientation
UIImage *photo = [self correctImageOrientation:img];
UIImageWriteToSavedPhotosAlbum(photo, nil, nil, nil);

return YES;
}

return NO;
}

// Right image orientation from UIImageOrientationRight (rotate on 90 degrees)
- (UIImage*)correctImageOrientation:(CGImageRef)image {

CGFloat width = CGImageGetWidth(image);
CGFloat height = CGImageGetHeight(image);
CGRect bounds = CGRectMake(0.0f, 0.0f, width, height);

CGFloat boundHeight = bounds.size.height;
bounds.size.height = bounds.size.width;
bounds.size.width = boundHeight;

CGAffineTransform transform = CGAffineTransformMakeTranslation(height, 0.0f);
transform = CGAffineTransformRotate(transform, M_PI / 2.0f);

UIGraphicsBeginImageContext(bounds.size);

CGContextRef perspective = UIGraphicsGetCurrentContext();

CGContextScaleCTM(perspective, – 1.0f, 1.0f);
CGContextTranslateCTM(perspective, -height, 0.0f);
CGContextConcatCTM(perspective, transform);

CGContextDrawImage(perspective, CGRectMake(0.0f, 0.0f, width, height), image);

UIImage *imageCopy = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

return imageCopy;
}

Another valuable inquiry is: in what moment can we hide the overlaying camera views and controls and make our own button? Trying the viewDidLoad… Oops… The camera view is still not made. Trying the viewWillAppear… The same thing… Trying the viewDidAppear… Yes, the views have been made and can be hidden now. Ok, we hide that and make a toolbar with our Shoot button. It works, but the screen flicks – we see how the standard views and buttons are shown and then hidden. How can we prevent this? I tried a number of ways and had found the best one: we should hide the views before they are added to the camera view (when the addSubview method of the camera view is called). It’s possible using Objective-C capability to replace the method dynamically at run-time. Ok, let’s replace the addSubview by our own method. In our method we can check that the passed view is one of the camera view subviews and set its’ “hidden” property to YES. So, we replace the addSubview in the viewWillAppear before the camera view is made. And we make our toolbar and Shoot button in the viewDidAppear after the camera view is made. Take a look at the code below:

// Replace “addSubview:” if called first time; hide camera controls otherwise.
- (void)viewWillAppear:(BOOL)animated {

[super viewWillAppear:animated];

if (toolBar != nil)
{
// The view was already appeared; we don’t need to subclass UIView
// but need to hide extra camera controls.
UIView *cameraView = [self findCamControlsLayerView:self.view];
if (cameraView)
{
cameraView = cameraView.superview;
int cnt = [cameraView.subviews regard];
if (cnt >= 4)
{
for (int i = 2; i < cnt – 1; i++)
{
UIView *v = [cameraView.subviews objectAtIndex:i];
v.hidden = YES;
}
}
}
}
else
{
// Subclass UIView and replace addSubview to hide the camera view controls on glide.
[RootViewController exchangeAddSubViewFor:self.view];
}
}

// Exchange addSubview: of UIView class; set our own myAddSubview instead
+ (void)exchangeAddSubViewFor:(UIView*)view {

SEL addSubviewSel = @selector(addSubview:);
Method originalAddSubviewMethod = class_getInstanceMethod([view class], addSubviewSel);

SEL myAddSubviewSel = @selector(myAddSubview:);
Method replacedAddSubviewMethod = class_getInstanceMethod([self class], myAddSubviewSel);

method_exchangeImplementations(originalAddSubviewMethod, replacedAddSubviewMethod);
}

// Add the subview to view; “self” points to the parent view.
// Set “hidden” to YES if the subview is the camera controls view.
- (void) myAddSubview:(UIView*)view {

UIView *parent = (UIView*)self;

BOOL done = NO;
Class cl = [view class];
NSString *desc = [cl description];

if ([desc compare:@"PLCropOverlay"] == NSOrderedSame)
{
for (NSUInteger i = 0; i < [view.subviews regard]; i++)
{
UIView *v = [view.subviews objectAtIndex:i];
v.hidden = YES;
}

done = YES;
}

[RootViewController exchangeAddSubViewFor:parent];

[parent addSubview:view];

if (!done)
[RootViewController exchangeAddSubViewFor:parent];
}

Whats Required From A Home Security Camera System

Selecting either a home security camera system, or a camera to be used for a commercial reason, can be frustrating if you don’t know what you are looking for in protection. For instance, do you want a real or fake home security camera system, meaning, do you need a system that will really alert the police, or do you feel that the aesthetic of having a camera visible on the premises is excellent enough to ward off predators? Are you interested in the way that a monitor is going to look? Do you want something that is obvious or discrete? Regardless of what your needs are, there is something that can come close to what you want. Cameras will come in three valuable forms, hopefully learning the basics will help to cut down on some future decisions.

The first kind of home security camera is renowned as a dome camera. Obviously, this camera comes in the shape of a dome and it fits conveniently on the ceiling of your home or business. You will find the dome cameras often times in casinos where they are used to monitor the tables. You will also find home security at its most fashionable with the dome lens. There are dome cameras that can be placed outside, but, you must use a special armor type in order to do this kind of mounting. Sony carries two different types of dome security cameras and they are a leader in the industry. You can choose from the Verifocal dome camera, which has the highest pledge (420 lines) and an adjustable lens. You can also buy Sony’s Infrared Armor dome camera, which acts as a hidden camera and is the most durable of all of the dome cameras. Dome cameras are the most well loved security cameras because they are impossible to detect which angle they are viewing unless you are at close array. They come in black or white and they all have adjustable lenses.

The second type of home security camera is the bullet camera. The lens is long and resembles a rifle, which is where the camera finds its name. Bullet cameras are easily visible and can be mounted to a wall or a ceiling. They use a 12V DC voltage, and the power cable should be included when the camera is bought. Most of these cameras will film in color and then change their resolutions to black and white when the light levels are decrease. The pledge during the day is much better with the bullet security systems, but if you have an alternate form of lighting, like a streetlight, people can sometimes be seen from up to 70 feet away. The most well loved brand of bullet security cameras is the SPECO CVC-6805SX, which is color and has a fixed lens of 4mm.

Many businesses rely on a home security camera at night. But, it can be hard to see the footage when there is no light. The infrared camera has built in lights around the lens so you are able to view your taped footage with ease. But, the infrared lighting can cause a problem when it is used at a home due to the glare that is made from the windows. Some people will reckon that an infrared camera is the same as a night vision camera, although the night vision camera does not have built in lighting around their lens. Prices can vary on the infrared cameras, but the most affordable home security model is the QSVC422 CCD color open-air camera made by Digital Peripheral Solutions.

Security cameras can provide a cushion of comfort for a secure home, especially when you have an investment that you want to protect. A home security camera can scare an obvious thief, and also catch an unsuspecting one if it is a strategically hidden camera. Home security cameras have become more well loved with people who own second and third homes, and feel like they need an insurance policy for their property, so to speak while the business owner has been protecting his own with security cameras since the advent of the entrepreneur. Just remember that it can never hurt to be proactive about your safety.
