HDR Photo Camera is a Windows Phone 8 app that gives your Windows Phone camera the capability of creating HDR (High Dynamic Range) images.
HDR images have a high dynamic range between the lightest and darkest areas of the photo than what you would see in standard photos. Typically HDR images are created by taking several photos of the same subject at various exposure levels and merging them together to create the HDR image. The end result creates an image with more vibrant colors and greater dynamic range between the lighter and darker areas. It's a great technique for landscapes and scenes that have a nice blend of dark and light areas.
While you could use the exposure compensation setting on your Windows Phone camera, bracket several photos and merge them into one image with post-processing software, HDR Photo Camera does it all for you in a simple, straight forward package. It's a nice camera tool to add to your Windows Phone photography app library.
