HDR Photography sometimes involves taking more photographs than one bracketed set allows, and working out the exposure settings required to cover the scene's dynamic range.

The HDR Exposure Calculator makes it quick and easy to find the number of exposures and bracketed sets to take, and the settings to use. The app takes the shortest and longest shutter speeds required for the scene, as well the camera's exposure bracketing range, and compiles a report listing:

- How many photos are needed in total
- How many AEB (Auto Exposure Bracketed) sets to take
- How many shots in each
- What exposure settings to use

The app is particularly helpful for photographers who need the best quality for their HDR merged results when photographing scenes with very dark and bright parts, such as real estate interiors with bright windows.
