Blend If Is the Sky Replacement Tool You Didn't Know You Already Had
There’s a specific kind of humiliation that comes from spending three days on a composite — cutting, masking, refining, swearing at your pen tool — only to have someone glance over your shoulder and say “why didn’t you just use Blend If?” I’ve been there. I didn’t even know what Blend If was at the time, which made it worse. It lives inside Layer Styles, a panel most people open by accident and immediately close, which means one of Photoshop’s most powerful compositing tools has been quietly sitting there, ignored, while the rest of us wrestled with layer masks like it’s 2009.
