Most of the time HDR bracketing with "frames autodetect" creates too many frames. The last frame is often unnecessary because it is extremely overexposed. See

I changed the overexposure and underexposure limits:

  • A darker frame is triggered if more than 0.15 % highlights are clipping

  • A brighter frame is triggered if more than 1.2 % shadows are clipping


  • The detection of clipping (over/underexposure) is based on the preview image (not raw), so it depends on white balance and picture style.
