Hi, I am trying out Affinity Photo at this point and I am confused about the following: I am under the impression that the Develop Persona is only for RAW files. If that is so, how come there is a Develop extension for the OS X Photo app which I have used successfully to work on TIFF and JPEG flies? Does that mean that I can also use the Develop Persona in Affinity to work on JPEG or TIFF files? If so, is there be any advantage in doing that? Moreover, if you are working on a RAW file in Affinity, do you necessarily need to edit the photo first in the Develop Persona before you can edit it in the Photo Persona? Thanks in advance for your help with this question.
