Does AutoHDR work better with lights off for white balance, and can I include flambient?

You can shoot with lights on or lights off — AutoHDR removes color casts from light sources either way. Flash shots are accepted but not needed to produce high-quality results.

Lights on vs. lights off

Either works. The AI handles color cast cleanup from ambient lighting sources automatically.

Flambient is optional

You can include a flash shot if you want, but the AI produces high-quality results from HDR brackets alone.
