[Layers out of register?]

Hi -- newbie to AF here. In scanning color photos, I'm seeing a slight shift in the color layers -- i.e. cyan out of alignment at the top and magenta and yellow at the bottom (see pix attached.) I tried using the chromatic aberration filter and defringe, but no change. I realize it could be an issue with my older Epson scanner, but Is there a way to nudge them back into register in AF?  Thanks!

Excellent -- thanks a bunch. When in doubt, read the manual

You can use the info panel View > Studio > Info which will give a colour value readout where the mouse pointer is. 

By default one sampler is RGB and one CMYK, You can change them by clicking on the icon (shown) or add extra samplers (burger menu) and have HSL too.

Not sure that is 100% what you want but I think it is the best option.

 

Perfect! Thank you. BTW, what does the crosshair icon do? It looks like it freezes on a set of values, but how do you get it to change to a different spot? Thanks again. 

[When to convert from RGB to CMYK]

I'm new to Affinity -- have used PS CS3 for years. Is there a way to work in RGB but show the CMYK percentages with the eyedropper tool? When I click on a swatch of the photo, it shows RGB percentages. I don't want to have to convert back and forth to CMYK to get my readings. Thanks!
