When I was a kid growing up in the east they used to have “snow days”—when school was called on account of snow. You went back to bed, covered your head with the blankets, forgot about homework, and looked forward to a blissful day playing in the snow.
What do you do when work is called on account of rain? Part of my answer is to go exploring with my camera in the rain, but when that gets old, I like to play with pixels—in this case LAB channel operations, Photoshop blending modes, mirroring, and reflecting.
