HDR photography on iPod Touch 4th Gen

When the iPod Touch 4th Generation was announced, it was disappointing to find out that the rear camera would be substantially lower in megapixels and quality than on iPhone 4, and would not feature HDR. HDR is high dynamic range photography. Your eyes are HDR, but a picture from a cameraphone is not because it takes pictures in a single exposure. Too long an exposure and all the dark areas have better detail with washout of lighter areas like the sky or light colored walls with patterns. Too short an exposure, and all the dark areas turn black, but details like clouds and cracks in white stucco come out. HDR is a way of combining elements of two or more pictures where the exposure is optimal for the particular region of the picture.

The result is a mix picture where all the elements in foreground, mid ground, and background get optimal exposure. The iPhone 4 has this mode of image taking -the only drawback is that because two pictures are taken, the camera must stay still. Alas, the iPod Touch did not come with this capability built in, but it wasn’t too soon before an App showed up in the App Store.

Pro HDR is the name of this app, and it’s great. The two images above were taken in the afternoon and the shots while not perfect, are good enough for the web. Pro HDR does a good job of stitching two images into one. At a &2.99, it is a great bargain.
