I started with a raw file like I said above Panasonic GH5 RW2 file. When you open a raw file it auto takes you to the develop. Well I know that when I batch a bunch of raw files it won't batch develop them so I usually zero out everything in the Raw Develop persona and then develop with no changes because I uncheck everything. That way I know it best represents the end result. Then I apply my Macro from that raw photo with no raw processing done to it. Once it looks how I like it, I save the macro to apply to my 500 plus images. But then they turn out a lot darker like it skipped some steps.
So I then re open a RW2 file and apply the macro manually through the library and it works like it should. So I know the macro is good. Just something wrong with the way it applies it when doing a batch. Could it be because they are raw? That would be a horrible flaw from affinity. Almost everyone I know only deals with raw images.
