The piece I did was an interesting composition with radical shifts of light. I liked the cool light gently filtering in through the skylights in the roof curves. I also thought the puddles helped draw the sky down through the composition. I was conscious of trying to balance those shifts and make sure I got as close as I could with the colour temperatures. The phone boxes offered a bit of a challenge because their intense colour could easily have stole the show. Hopefully I got the balance somewhere near the right sort of level, tempered with a touch of viridian and ultramarine to knock it back slightly. It was great to see how the other artists approached the same subject. The somewhat 'unifinished' look I attribute to the grittier nature of the subject :o)
Compare my study with the photo below. Those telephone boxes don't half scream at you which is why I toned them down by adding Viridian. Notice too how the lights are totally bleached out by the camera. This is one of the reasons I much prefer painting directly from the subject. Couple that with the fact that I find working from photos a pretty dull affair. The energy of the moment is what guides me. I find the camera often kills the subject but it can be handy for reminders of details.
