On a recent painting trip it rained and I kept painting anyway. The rain fell on my palette and painting but the oil and water seemed to stay separate. I did my best en plein air piece so far...
I left it alone in the studio to dry and came back a few days later. I was pretty gutted by what I saw. The whole piece was now covered with a network or cracks and all the darks had chalked out. Stupid rain and stupid Jake! The problem was exacerbated by the fact that the board I used had a heavy amount of old (several months dry) paint on it so the old thin over lean rule was broken.
I will be adding a big umbrella to my painting kit asap.
Here is the piece including a detail:
