I had lost my SD card, so I had to take new images this morning. It was very impromptu, but I had a lot of fun with it!
Image 1: f/10, 1/800s, ISO 3200, 49mm focal length
Image 2: f/13, 1/160s, ISO 3200, 28mm focal length
Image 3: f/4.5, 1/400s, ISO 3200, 35mm focal length
All shot with a 55mm lens, compulsory no-flash, with pattern focal metering and no exposure bias.
