How RAW and AVIF differ in practice
RAW files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to AVIF bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after. RAW carries 14 bits per channel and AVIF carries 12, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to a 12-bit format only at the very end.
