I have worked in PS since '94, and I am totally stumped ...
I have some png blood smears I really want to use in post, but they're all grey. I don't mean grey-scale. I mean RGB mode, but grey.
At first, I assumed a simple 'replace color' or 'variation' change would do the trick ...
No matter what I try, tweaking saturation, hue, anything, gets me nowhere.
Thanks for any help ya'll can offer.
