This is a follow up to the "Study of Triangles" blog post from last weekend. It was a beautiful, sunny Berlin Sunday and I couldn't resist heading outside to bask in the incredible sunshine – with a purpose, of course. After the triangle exercise last week, I was curious about the next shape or theme I could focus on in a series. I decided on the circle this time, and was surprised how easy it was to find circles to photograph. There were too many! The challenge then became finding interesting compositions and unique circles – not just street signs and doorknobs. I'm happy with many of the images I made on Sunday, and again appreciative of the exercise and the challenge of seeing my surroundings in a new way. The time of day I photographed was mid afternoon though, and the shadows were long and glorious. Perhaps next time I do this on a sunny day, I will do a shadow challenge. Or post-rain in Berlin, I'll work on a reflections challenge. I'm curious to see what I can make.
