CR2 to ICO: what to expect from the conversion
CR2 files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to ICO 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. CR2 carries 14 bits per channel and ICO 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.
