The plan was to paint in Trafalgar Square at night after the rain.
The rain stopped for just long enough for me to set up and start painting. But, 25 minutes into the picture the rain became so heavy I had to pack up. You can see how far I got in the picture above.
Above: Rain water on my palette.
But what an adventure and what a mood the work got (for what I can see) I these circumstances a open box become more handy, you can paint upwards and hold you panel as some sort as umbrella.
I would love to see the result in a little more detail though.
