In the bad old days before digital I'd typically load up a negative, choose a paper size (I'd generally want 1280x720), and then adjust the enlarger and paper frame position for "zoom", "pan", and "rotation". I have yet to figure out how to do this basic workflow simply in any photo editor? I'm trying to use a simple point'n'shoot 18mp camera that has no optical zoom - ignoring the digital zoom and doing that in post.
I have used Paint.net quite a lot for other operations.
Thanks!
