decals,logos and alpha channels( oh my)

Ruz

I am trying to paste some decals logos and into my alpha channel.

I did some decal overlays( mainly corporate logos) in deep paint in projection mode, saved out the decal layer as a tga and copied and pasted it in to an alpha channel in pshop

problem is the logos were a variety of differing colours/shades/intensrties and I

want a simple cut out of all the differing shapes ie black and white

I tried using desaturate then equalize, but I get horrible jaggy edges on my type/logos and I want to keep my high quality edges.

Is there a way around this ?

in hindsight I perhaps should have used black and white for my logos/type in deep paint and then used the apha channel to select and colour them after.

for example if you take the polycount logo which is green and the white lettering next to polycount, I would need to equalize them so the are both pure white and still keep the crisp edges

Use the curves tool if you want to keep a little antialiasing on your alpha. Pull the graph so its almost a vertical line on the right side the window and you should get something workable. It might need a little clean up if you've got any strong whites in your decals, but it'll be close.
