How to make Light Diffusers for mere pocket change.

Imagine my surprise when I was starting to do some Motion Tracking experiments and pulled out some lighting rigs, deflectors and diffusers from storage only to find that they had been a meal for film hating mice and or squirrels (its hard to tell out here in the redneck Serengeti). That's one thing I can't tolerate cynical critics and film hating wild animals ( well the two are one in the same really). It was time for me to think fast and create some replacements to keep me on schedule- most importantly replace the diffusers.

It started out simple enough, I just happened to have some white coat hangers. Why white do you ask? Well, the white ( I assumed) wouldn't make nearly as much of a shadow as black or the more popular yellowish copper colored ones. Worse case scenario a pack of white coat hangers will put you out about 1 dollar. So in production terms we're talking twelve in a pack, or about 8.3 cents a piece.

Next you take two atrophied arms (assuming you have been doing as much editing, compositing and computer work as I have without sunshine or proper exercise) and pull the wire hangers in about as perfect a circle as you can get them. Cost for this step: absolutely free.



Next you cut out a section of a cheap "party table cloth" (usually anywhere from .25 cents to $1.00). In this case I used those plastic translucent pillowcase protectors. One could also use white kitchen trash bags, and in a pinch "suit bags" of the same material that can be found for no more than a dollar or two. Cut the material into segments to fit the wire hanger, making sure that a little material spills around the hanger to make a lip. Then it is a matter of stretching it taut and figuring how to fasten it with whatever means you have available- be it hot glue or duct or gaffer's tape. I like the reflective quality of duct tape and seemed to make less shadows than the gaffer's tape.

After fixing the material, and fastening appropriately - Its time to think about fastening it to the light fixture. Lets hope that you have a few light weight spring clamps around. If not, it is possible to fasten the diffuser with some C47's (clothespins) although it takes many and can get a little tedious while trying to reposition the diffuser.

And Viola!! Your back on schedule and not breaking your budget. (see pic at top) I came. I saw. I adapted. Now if a squirrel/mouse could evolve to the brink of having an interest in cinema, we wouldn't have these problems.

Thanks for dropping by,
