RGB & Luminance
What do you do to add the Luminance channel to your RGB images. It's been puzzling me for a while. My efforts have always overloaded the channel I've added it to and unbalanced the colours in the image.
Forgive me if you guys already know this process but I've discovered L*a*b colour. Anyone familiar with it's use ? I watched a video that showed how to switch to Lab colour mode then add L as another layer, adjust it's luminosity % in properties then flatten the image and revert back to RGB. It essentially just boosts all the colour saturations equally so no colour balance problems. Looks like I might be going back to some earlier images and having another go at them. Might as well, weather has not been very helpful lately
