Apple introduced High Dynamic Range (HDR) photography along with the iPhone 4 and iOS 4. HDR will automatically produce improved camera shots by combining three camera shots into one image. The HDR setting in the Camera app remains in iOS 5 and the new iPhone 4S.
That isn’t necessarily a good thing if you are prone to using the camera in your iPhone and HDR a lot, because HDR produces two images which are stored on your camera roll: the original and the HDR enhanced one. If your device has limited storage space this could start to be a problem.
If you have an iPhone 4S the images produced by the 8 Megapixel camera are larger than the ones produced on the iPhone 4 or iPhone 3Gs. Luckily there is a way for you to force the Camera app to only save the HDR image.
