There's a really beautiful video of artist Robert Genn painting plein aire on YouTube. He said he's been using M. Graham acrylics lately, and finds that they have a longer open time than Golden with a similar pigment load. I'm heavily invested in the Golden line, but I must admit that I'm intrigued by the M. Graham acrylics. I'll live vicariously for a bit. Let me know if you try them!
