Real paintwork material and its iteraction (photo n video for the model testing)

[roma Golich]

Dear sirs, it would be intriguing to see how the real paints' interblend and interact with the canvas (e.g., water-color techs — dry on dry, wet on wet, et cetera.) The material compatibility (chemical, grinding n color, e.g.) The tempera formula, etc. Thank You!

And... the van Eyck brother secret ;)
