Michael,

I am a painter, and am used to work with middle aged techniques liuke egg tempera.
My enthusiasm made me forget that there are also people who use PS for their nerve-wrecking job (working with printers etc.)
I saw and see it as a tool to create art, and, yes, err, you remember perhaps from long ago, the wow-effect...

As for the other colours, of course you have to mask and make selections.

It won't happen again, this was my last post. I leave the stage to you, professionals.
