I'm pleased to say that the coloring is complete on my portraits of these four pioneers of Earth imaging. I used a combination of Adobe Illustrator (with help from Astute Graphics add-ons for texture) and Manga Studio for touch-up work and detail.
I sent the files out for printing at Bay Photo for display at the Planet Labs office in San Francisco. They look great printed big on Kodak Endura Metallic paper mounted on Gatorfoam board.
