Does AutoHDR work with flash or flambient shooting?

Yes — AutoHDR accepts flash frames alongside your HDR brackets. That said, you don't need to include them.

Why bracket-only often works better

AutoHDR is trained to produce flambient-quality results from 3-bracket HDR alone. Most photographers who switch to bracket-only find the results are equal or better, with significantly less shooting and upload time.

If you want to keep shooting flash

Include flash frames in your upload the same way you would brackets — they'll be accepted as part of your bracket set.
