So I finished a can of Pringles today and was messing around with the lid. I found out that the plastic lid works perfectly as a lens cover for my 200mm zoom lens. So I decided to look around the internet for some other mods using Pringles products and found this one: http://photocritic.org/macro-photography-on-a-budget/
Basically, you use a Pringles can to get some insane macro shots with a 50mm lens. Looked like a fun little project and I might have to try it out myself. Has anyone ever done this before? Any other little DIY mods like this?
