Dark screen effect in Photoshop 7

Can anyone tell me the technique for getting the dark screend look like is these Wonderfalls icons. Ans the golden screened look in the LiT one?



All three were made by _jems_

I have some idea how to do it, but I'd like to know a direct technique. I've been seeing the look a lot and would really like to experiment with it. I've done varations of it myself with bright vivid colors, but not the black. I was wondering if it's done with icon sized screen brushes, or if it's by flood filling a new layer and blending it in screen mode or something.

I'm using Photoshop 7 by the way.

Also, I'd go scour the memories (which I'm probably going to do anyway) buy LJ is being extremely bitchy right now that I want to just go ahead and get my question out there.

Thanks in advance. Oh, and before anyone suggests it, I did go straight to the source too. Just covering all bases ;-)
