It has been raining all day and I was hoping to experiment with how flash and light falloff would impact a photo of the rain. However, I was in a slight hurry which rendered me unsuccessful. Walking back into the house, I noticed how the sunlight was streaming through the curtains. They reminded me of birch trees. I took a few photos and combined them in Photoshop, changing the blending modes to get this abstract effect.
