James Gurney Actually I've started doing some of my finished paintings in gouache. There's no reason gouache can't be used for big, detailed, or finished paintings. When I started my illustration career, I did several of my big paintings in a combination of gouache and acrylic.
Norm G "You know what is the biggest "secret" to an awesome painting that I was able to take away from all your videos? It it the way you paint a lot of your scenes back lit. That has opened a whole new world for me.. Thanks so much for your videos, you have really giving me a boost to get back into painting and my paintings now have much more life and depth to them! 👊😎"
James Gurney Yes, Norm, you're right. I'm crazy about "contre-jour" lighting or backlighting. It automatically creates a strong feeling of light and spatial depth. Here's a blog post with more information about contre jour lighting .
Fernandojra "Aside from composition, what are the differences between casein, acrylic gouache and regular gouache? Do they all reactivate with water after dry? Any opacity or sheen differences, etc?
James Gurney All are relatively matte and opaque, especially when combined with white. I use the casein very thinly over the paper. If the casein layer is too thick, the gouache will bead up. Regular gouache will reactivate with water after dry. Acrylic gouache seals when dry, because it's really a form of acrylic. Casein is halfway in between gouache and acrylic gouache. It can reactivate after setting up if you scrub at it, but over time it becomes more sealed.
Stephen Halpin Thank you! I would have thought that the casein underlayer would throw your judgment of color off, but it's such a pleasure to see how spot-on your colors are. Does the color in the underlayer make it more difficult to get those initial colors right, or does it somehow help?
James Gurney Yes, very perceptive question. I think I was fighting the underpainting a little, like riding a bicycle into a headwind. I like that feeling of resistance. I intended a relatively cool palette for this painting, so I was forced into opacity.
