If you have an iPhone, you need the $2 Pro HDR app. HDR photography (High dynamic range imaging) combines a dark exposure and a light exposure of the same scene to create an picture with far more color depth than a “regular” digital image. Even though my iPhone4 has a built-in camera HDR feature, without a special app I can’t manually adjust brightness, contrast, and other settings which I find essential to take high quality iPhone HDR images.

Today I had an opportunity to visit Mammoth Hot Springs in Yellowstone National Park, and thanks to Pro HDR I was able to take the following images. Anytime a photographic scene has extremely bright elements along with dark elements, it can be well suited for HDR photography. These is particularly true of many landscape scenes. There’s no way I could have captured images in Yellowstone with this much color depth without an HDR photography app.

The main reason an HDR image might not work well in a scene with bright and dark elements is if there significant movement in the frame. In those cases, you may be better off sticking with a ‘standard’ digital image.
