Can AutoHDR accept flash frames for flambient?

Yes — flash frames are accepted. That said, AutoHDR produces very high-quality results without flash, so you can simplify your shooting workflow with 3-bracket JPEG and get the same quality.

Flash is optional

The AI is trained to match flambient-quality results from 3-bracket HDR alone. Skipping flash saves time and hassle on-site without compromising the final edit.

Recommendation

Try 3-bracket JPEG without flash and compare for yourself.
