How is exposure bracketing done?
Exposure bracketing is shooting the same scene at several different exposures in quick succession. Most cameras automate this: set to bracket by one or two stops and the camera fires a burst, one frame at the metered exposure, one underexposed, one overexposed. The darker frame retains detail in the highlights; the brighter frame opens up the shadows. Merged together, they cover more of the tonal range than any single frame can.
In our online HDR editor you're able to merge your exposures and adjust the look, even choose how "compressed" or physically accurate you want your final HDR image:
How many frames do you need?
Three frames at one-stop intervals work for most scenes with moderate contrast. For high-contrast scenes (direct sunlight against a dark interior, for example) five frames at two stops apart gives more overlap and reduces visible seams at the blend boundaries. Going beyond five rarely adds useful information; the outer frames are usually clipping on both ends anyway.
How to merge your bracketed shots
- Drop your bracketed frames into the upload area above. RAW files give the cleanest merge; JPEG sets work but start with less tonal information.
- Click Merge. The tool aligns the frames and blends them (a few seconds for most sets).
- Adjust the result in the built-in editor and export when done.
