For taking pictures of parties, I wanted something that I could use so people don't look like rabbits in headlights and softened the lighting.
I also needed something with simple light weight construction that I can slip into my already heavy camera bag. I'm also broke from spending around 1800 dollars on camera gear. I have no more money left for an external flash. Paper is a tolerable diffuser.
This instructable inspired me, but I don't want to be branded a smoker (even though I do occasionally):

ONE MORE THING:
I'M NOT RESPONSIBLE FOR ANY PROBLEMS YOU HAVE. EVER. OR WITH THIS PROJECT.
Step 1: Testing
I later gave up and made the diffuser modifiable for your needs. You can find one location and leave it there.
