Blogging my paintings at each stage is very useful to me; I can look back and re-experience the combinations of colors, the shaping of the painting. Not only that, I can see the painting at a smaller size. That is very much like moving way back and squinting. I can see flaws that I may not spot close up.
I have the iPhone to thank for that. It takes pretty darn good photos, and though the color is not perfect, it is good enough.
Blogs are fab for this!
Color scheme: blue-green and red-orange (no kidding! LOL).
