I "should" have called this, "Don't Paint in the Dark!"
When I really get into a painting, I'm not aware of anything else!
It was late in the afternoon when I started painting and the sun was setting fast. I had my still life setup of the pears lite, but didn't have a light on my palette because I was using the daylight. When I finished, I brought my light stand around to light my panel and was surprised at not only the colors, but the knife strokes as well!
So my lesson learned for today is, light both your subject and your palette.
I hate when I have to learn things over and over!
So you might say, "why don't you fix it?"
I don't like to go back into a painting,
I have found it rarely works for me, and just becomes fussy.
