An Unusual Form of Light Painting

Step by step tutorial on making beautiful abstract Refractographs; caustic patterns produced as light reflects and refracts through an object. [check the via for some amazing examples]
I'll be doing both this and the "glow sticks in a waterfall" thing in the near future.

Ooohsopretty.
Definately on my camera projects list now!
Thanks for the post.

Not only is this post about beautiful photos produced through a unique technique, but I learned a new definition today.
From the sentence structure, I assumed caustic was a fancy way of saying 'caused by', but it's quite specific:
caustic--The enveloping surface formed by light rays reflecting or refracting from a curved surface, especially one with spherical aberration.
Light is fun to play with.

I'm wondering if I could make this work with my green lazer... Eye damage incoming...

Caustic... patterns?
Ah, learn something new every day! All the optics I studied and I never learned this term... rassum frassum education.

The narrator advises against it; the laser will likely damage the sensor in your camera. Though I imagine if you had enough refraction, you might be able to get away with it. I don't know that I'd want to risk my camera on that chance though.

guess I missed that part by watching without sound, I tried it but was just getting mostly green haze (used a diamond cut glass 'crystal')

I did this a while back using a laser, projecting the refracted light onto photo paper. It was fun.

I need to try this. I remember my intro photography professor mentioning at the beginning of class that he could create images in the dark using only a small flashlight as a light source. I suppose this is another method. There's one point I didn't understand, though: what are they using to hold the glass in a stable position?

As a rendering engineer I love to see the word Caustic come up in non-mathematically related posts.
As a photographer I am trying this as soon as I get home.
