This is a question that's been bugging me for some time now:
In photoshop/GIMP, there is a "screen" layer composition mode. This mode has bright colours have a strong alpha, and dark colours a weak one. Black is entirely transparent, white entirely opaque.
I would dearly love to be able to replicate this composite using Java 2D graphics, but my repeated attempts at trying to coax AlphaComposite into this have failed - and indeed I think this is outside of AlphaComposite's capabilities.
A visual example can be seen here .
Any ideas on how to do this?

Looks like some reference code is here:
