VSI to BMP: what to expect from the conversion

VSI carries 16 bits per channel and BMP carries 8, 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 an 8-bit format only at the very end. One VSI file can hold several pages or frames, while BMP holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.

What are BMP files?
