[Alt-photo] casein on glass

[Matti Koskinen]

hi,

I've been long enough a consumer and not a producer, so I wrote a page 
of my casein method. It's on http://www.mattikoskinenphoto.com/casein

Thanks to all, especially Jorj, who directed me using glass as a substrate.

And a question: What are the names for CMY-colours, I think C is 
Prussian Blue, but M and Y? I'm using acrylic paints.

thanks
