Hi Nico,
these formulas are used in many area's in blender. and have been for ages. We cannot change them without breaking other stuff. They just work differnt then you expect.

No it's not about formulas not being correct, it's because our compositor is working in Linear Color Space (and floating point), and your Photoshop examples are in sRGB display space.
The formulas in Blender are 100% identical to what other programs use. There's really only 1 way to add, subtract or multiply :)
Try to do a comparison in Nuke or any good compositor supporting linear color compo.

I rewatched CompositingInBlender DVD and i realized it says exactly same thing...
