Hi, I'm trying to figure out if there's a way to make color picker in White Balance Adjustement working in the way I want. I scan lots of negatives and white balance is really important and not easy to achieve. not only in the blue/yellow axis but also on the magenta/green axis. the color picker could be a great help for that, in particular the possibility to add average multiple whitepoints. I do scan with Silverfast and this software has a tool that works just like that: you sample up to 4 points and you get average white balance on all the color axis. but sometimes I need to do this task after the scan has been made.
But from what I see, the Affinity Photo color picker works just for blue/yellow but not for magenta/green. that is a big limitation. In apple photos there is a similar function and it works also for magenta/green. but you can choose only one point and that is usually not enough.
a workaround could be to use the info pane and LAB values and do it manually, but there is another problem: the Info Pane Sampler gives values for just one pixel, you can't average 3X3 or larger areas, making useless for this purpose.
any solutions?
thanks
