Playing with the same glass piece I used in Colliding Worlds and a green laser projecting through it on a whiteboard. Laser and glass are being held by hand on a low table until I have a composition I'm happy with. I start the exposure trying to stay very still, using my knee to lock the glass and laser in place. on some shots I moved the glass as fast as possible to a slightly different position during the exposure and held for a few more seconds. The laser is actually green but I like to use it with a cold white balance to create a shade of blue that I prefer over using a blue laser.
I'm also on Instagram - Facebook - Flickr - Vimeo - Twitter
