The other day I mentioned that I have been using a new process for my speedpaints. Instead of starting from a blank canvas and than filling it with a midtone, I am starting with a pre-textured canvas as seen here:
This is two different 'concrete' textures overlayed on top of each other with some tweaking. On top of that is a color layer with various colors in the corners. Starting with this pre-prepped canvas gives me all the tones and colors I need so that I don't have to worry about mixing them. This helps make the process that much faster.
Here is a video where you can see in 3 minutes the 30 minute process:
P.S. The textures are from this site.
