Photoshop Help

I need some help. If there's a stock with a black background and I set it to screen, it doesn't remove the background. It used to work perfectly before, but now it's not working and I have absolutely no idea why. What should I try doing?

Thanks in advance! ^_^

 

try addingt an alpha channel, then color to aplha=black

 

What?

 

Is there a transparent layer behind the render?
Put a gray bg and see how it goes - The screen effect doesn't work on transparent backgrounds

 

make sure u have an alpha channel, otherwise add one. the go
Color to alpha > black

 

Fucking grats on finally getting your rank and shortened name <333333333333333333333333333333333333 Now you just need your UI haha

If you aren't sure how to do this you could always try and make a selection around the render with pen tool, quick selection or magic wand I guess.

 

Like said above screen only works on a bg, not with transparency. Try feathering out all of the black from the stock with the soft eraser.
