Developing a raw Z6 16 bit image in Affinity on Desktop Questions (Mac and Windows) Posted September 23 Thanks for replying Lee. My Mac is Sierra 10.12.6, Affinity is 1.7.2 and I am using Photomechanic 5 to import into Affinity. I have clicked to SerifLABS. After I have worked on an image in Develop Persona I then hit the Photo Persona button and it took about 25secs to develop. Is this time normal?
