first you gotta cry at photoshop, it won’t get the work done but it’ll make you feel better.
then you can read these pages: here, here (she does such and amazing job jfc) & here
they really helped me out a lot :’) also you could check out if some of your favorite edit makers that master photoshop beautifully has a FAQ
and mostly just mess with photoshop a lot (which is what i do most of the time tbh), have fun and i’m sure you’ll find something that’ll work out for you. it’s pretty much a trial and error sort of thing :’)
omg this isn’t helpful at all, sorry! but if you have more questions don’t hesitate to ask me :)
