The gym I go to has a long hallway with a beautiful dome top where sunlight can come in. In the dome at the top of the image and the lights, doors, and hallway at the bottom of the image used geometry to build. Then to utilize empty space, they added a really sweet quote that everyone can read when they look up. Looking at this hallway does make me smile. In this image, the aperture is F5.6, shutter speed is 1/64, and ISO100.
