The photo was created after being inspired by the photos in the book by Hiroshi Sugimoto (cover photo) Chapter - "OPTICKS".
Equipment: Sony A7II, no lens.
Settings: f/0 ISO 2500 1/200
My substrate was Peli Case Yellow. Then I added a second layer, a blue T-shirt, which gave me a shade of green. The whole thing was illuminated from the side by a table lamp, approximately 3500K. The beam of light was directed down -> onto the countertop, so only part of the light illuminated the Peli Case.
