Mark Carder is a self-taught painter who has developed quite a good reputation and business.
He not only creates fabulous paintings, but he also develops products used in oil-painting. I like his line of premium paints.
He markets his high quality, hand made, oil-paints and accessories at Geneva Fine Art Supplies.
Mark has been commissioned to paint two United States Presidents and a Secretary of State. His paintings are barely distinguishable from photographs.
The goal of his "DrawMixPaint" YouTube channel is to "... eventually, cover all essential instruction for painting realism in oil so that anyone can learn to paint for free."
Sounds good to me. Mark has been posting "how-to" videos for the last seven years. If you want to learn how to paint realist paintings, his channel is a perfect choice. I hope you get a chance to see those videos and learn a little bit more about the process. You can see his work on his art website, you can learn from him on DrawMixPaint website, or you can buy any of his products on his Geneva Fine Art website.
Now go out and make some ART!
