HDR Photography

1. At the most basic level, an HDR photo is just multiple photos taken at different exposure levels and then mashed together with software to create a better picture.
2. A tripod, a camera with an Auto Exposure Bracketing function, and an HDR blending software. 
3. Any photographer wanting to capture a scene with really dark and really light areas will ant to use HDR photography.

4. Details that are really dark or really light in an image will be seen better using HDR photography.
