I've started using Hasselblad Phocus (3.3.6) to organise and clean up my photo collection, and having shot primarily in JPEG, am missing the White Balance and Noise Filter menu items, amongst others. I can't find anything in the documentation - is it really the case that these menu items are only active for RAW images?
Phocus primarily fully supports Hasselblad 3FR and 3F files with more limited support for other format files.
This is true for most RAW converters. Some do try to offer some/all options to JPEG as well, but since they lack the information that RAW files still have, it is a different algorithm that has to interpolate the missing information, while RAW white balance correction is relatively easy. My personal guess is that most developers think that RAW is the format that people use to edit their picture.
