Okay, so I like editing pictures and stuff, but I am REALLY bad at it. I'm semi-experienced with Photoshop (I can do basic things LOL) but I can't find a method to extract a person from their background. Like, just say I wanted to use 3 pics of Carrie from 3 completely different photoshoots, how would I combine those into one picture without each picture having a background around them? That's basically my main problem right now. What methods do you use?
