Justin,
Many thanks for your response. I think the first issue is that rather than being ignored, we should have been told the dropdown was disabled. This is not disclosed on the tutorials which shows it as now functioning and with all the inquires, this is the first advice of the issue and the question has been raised for some extended time.
I can only speak for myself as to expectations and I am a professional user, but I would expect something comparable to the ACR/LR/ C1 camera choices. If not, at least a user friendly way of making our own usable profiles if it applies to our work flow. As was discussed on another well known forum earlier today, If AP is soley relying on Apple camera profiles, a very large work in progress is in store to try to create a PC version of the application. I was primarily a Canon user until 2 weeks ago at which point I made a switch to the Nikon system. This means for me, I have files, and will have files for some extended time that I must be able to process in a timely, accurate manner across camera platform for my clients. Profiles and the ability to create profiles to match each other are of paramount importance to me. Others use may very, but most if not all users are at some point tied to color profiles/camera profiles/ and calibration of their monitors all coming together to produce the desired digital or print file.
Thank you once again for your response.
