I want to use Affinity Photo to correct film scans so that I have a systematic way to correct skin tones using the vectorscope. I have seen some tutorials with video editors, and I wonder if there are any good workflow examples with AP. I come from Lightroom and I am new to AP, so many things I do is still very inefficient. For example, when I want the vectorscope to only measure the skin I do: crop part of skin -> adjust tones with wb adjustment layer -> copy wb adjustment layer -> go back in history to undo crop -> paste wb adjustment layer. There has to be a more elegant way?
