Black Lights & Bubble Wrap....
Jan 10, 2014 01:08:22 #
Cold, wet, foggy... In general, a pretty dismal day. I had to pick up some stuff at Home Depot and grabbed a florescent black light on my way out thinking that I might do something with it......

ajohnston3: I am enthralled with the second shot. It looks like molten lava running beneath a surface which has cooled. Will you shed some little on it? I really like it. Thanks for posting,

Very creative. My local Home Depot has these bulbs in a variety of colors- you gave me something to think about. Question: the bubble wrap was backlit for this photo- right? ;)

Thanks for the kind words..... I used a Nikon D5100 in 'M' with a tripod & remote release & a Sigma 70-300mm f/4-5.6 SLD DG lens in macro mode...
ISO-100
F-14
Exposure time 4 sec.
Focal length 300mm DX (450mm FX equiv.)
I turned off all the lights in the dining room and used the black light in an articulated desk lamp as my only light source. I placed a sheet of bubble wrap on a black hand towel and placed the lamp just above it at one end at a 10-12 degree downward angle. Thinking back, I realize that I purchased a blue fluorescent along with the UV bulb. I'm pretty sure I used the blue one for this shot.... The 'molten lava' effect must be from light defraction in the individual cells.... A serendipitous event indeed!

Not on this shot. I think it was a result of detraction in the cells that caused the unusual effect. I do think that trying this again using a diffused back light source might achieve even more interesting results. Perhaps with one of the other colors....

LOL, I read right over the typo. Thanks for the clarification- I couldn't decide where the light was and my best guess was it was backlit in part, I think, because I didn't consider that the wrap could be laying on a black background. It would be interesting to see what you get if you try backlighting. ;)

That's what happens when you experiment. You create special effects. Very powerful. Thanks for sharing.
