As I continue my work on luminosity I will share a few things I have observed:
1.luminosity does not need a dark
2.luminosity needs grays and in the luminous area pure chroma
3.the luminous area must be small and the grayed down area large
I have found that working on the watercolor on site and then in the studio creating the full concept in the studio allows for more focus on the concept of luminosity. I will rub and erase the pastel and use fixative in numerous layers.
