Yesterday I painted a bakery case with watercolors. (Link to YouTube)
The challenge was to paint the pastry seen through the glass and reflection skylights.
This is difficult because the brain can not see these two areas that overlap in the same time. The camera easier because it is monocular.
In stage pencil, I put perspective and also the forms of reflection areas. In the area of each light reflection, I got the values to a higher color. As it was transparent watercolor, I had to do it without resorting to opaque gouache.
