I found a photo app, Prisma, for the iphone that takes a photo and reworks it in various art styles. It’s given me some ideas about trying different color harmonies and line quality. Here’s some examples using the same photo:
Composition
Dallas
Femme
I also found this interesting blog post that I wanted to share with you, “Painting Fundamentals for the Advanced Artist”. The artist summaries all the notes he’s taken over the years from various art books and workshops.
