kaleidoscopes
When I visited Camera Obscura in Edinburgh I had a fun day playing around with the optical illusions there and I bought a kaleidoscope from the gift shop.
I've been playing around with the patterns and geometric shapes made by using a kaleidoscope with some of the research photos I've taken.
Above is a photo from Camera Obscura and below a selection of images taken using a kaleidoscope app.
I love some of the patterns made in the kaleidoscope images, I think its a really interesting way to make repeating patterns.
