This past week my photography group took a field trip to The Ringling Museum in Sarasota. Several of us brought along a new toy we had purchased, a 80mm Crystal Ball with a small square crystal cube stand. I bought mine months ago and have never had the opportunity to pull it out and experiment photographing images through it until that day.
Setting the stand and ball on a flat surface you focus the camera through the ball to capture an image. The photo is now upside down, tiny and slightly distorted into a sphere shape. When the photo is flipped in post processing you now have a tiny world inside the crystal ball.
