Lately, I've been very interested in experimenting with various glass/flashlights/translucent objects to distort the frame. I wanted to gather feedback from other people on objects or techniques they've found to work well.
I've used various pieces of beveled glass, vaseline smeared on UV filter, water bottle and got some pretty cool results. Using a flashlight to veil the lens gets pretty nice results, but it's hard to find consistency using some of these techniques since the results are so variable.
Anyone ever rig a flashlight to 15mm rails so the veil stays in the same spot? I'm also interested in getting the "double edge" look and experimenting with glass beads.
It seems that when using caustics two of the big rules are: 1. Use longer focal lengths. 2. Shoot into backlight.
Two notable examples:
