Request a new feature, or support for a camera/lens that you would like to use in Capture One.
The inclusion of rulers for accurate cropping would be a huge boost to the program and seemingly a simple addition compared to the tech you already include.
In my case I’ll shoot an artwork on a white wall centering it as best I can by eye in the view finder of the camera . Then the client wants it accurately centered for their presentation / publication purposes. Often my clients are seeking a finished image delivered from me, I don’t use photoshop as I find capture one and precise photographic procedure create excellent results except this cropping issue. I’m hoping for this seemingly minor addition to your workflow ..
Thanks it would help every photographer I’m certain, especially since you’ve ventured into post production a bit with layers, rubber stamp and healing
