I had a set of Casein paints sitting in my shelf for a few months now. I bought them when James Gurney released his Casein in the Wild video. I never got a chance to play with them simce then, things were a little too hectic to get started with a new medium.
We kept this long weekend free of all activities, so I got a chance to break open the new set, get a palette prepped, setup a simple still life and just have a go at it.
It was a chqllenge working in this medium that activates with water but behaves nothing like watercolor. It is neither opaque nor transparent and i had a hard time figuring out what to do with it. Granted it is just a first painting and things take longer than an hour to learn :-)
