DIY Flash diffuser for point-and-shoot digital camera

There aren't many solutions for softening the harsh flash of a point-and-shoot digital camera.  I've tried holding a piece of paper in front of the flash - and that works to a point - but I get inconsistent results, probably because it's hard to consistently angle the paper correctly.  There's a commercial solution, but it costs $20 and the manufacturer actually makes two models to fit different cameras, which means it may not be easily interchangeable from one camera to the next.

I show a way to cut a medicine cup to hold a piece of vellum or paper at a consistent angle in front of your flash.

Step 1: Materials

*A medicine cup with a bottom diameter smaller than the diameter of your camera lens (measured where the lens enters the camera body)
*A squarish piece of vellum about 2 inches on a side.  I imagine other translucent material would work too, but vellum works well because it's lightweight and stiff.  I used a piece salvaged from a fancy invitation.
*Clear packing tape
*A piece of paper about the size of a 2 to 3 inch post-it
*Something to cut with (scissors, exacto knife)

Step 2: Cut the medicine cup

Cut the medicine cup into the shape shown - a ring with a tab.  The ring should fit around the lens just tightly enough to keep it from falling off.  You want to be able to rotate the diffuser on the lens easily without tugging on the lens too much.  If your ring ends up being a little too loose, use packing tape to narrow its internal diameter.

Step 3: Attach diffuser to the tab

Tape the piece of vellum to the tab.  My piece of vellum is about two inches on a side.  You will probably have to do a little experimenting to size the vellum.  I considered making mine bigger, but I was limited by the size of my old invitation.

Step 4: Mount the diffuser on the camera

Slip the ring around the camera lens such that there is some distance between the flash and the diffuser's flat surface.
Angle the diffuser so it doesn't block the autofocus beam or the viewfinder if you're using one.

Here is a couple pics of the "Proto type i made, this one I shot a thin coat of white spray paint over but had to sand it off cause it didnt work too well, but in sanding the paint off, i got too crazy and made the disc too thin and it cracked...lol

i took one of those clear cd's that come in the stacks of blank cd's as a protector for the bottom CD so it doesnt get scratched... i drilled out the hole in the center with a hole saw so it fits snuggly around the lens on my canon sd850IS when its fully opened. then i used a really sharp razor knife to cut the CD into a sort of tear drop shape so that the hole for the lens was at the bottom almost at the point of the teardrop, the part thats usually on top of a tear drop when you draw one. I then scuffed the CD up really good with some fine grit sandpaper and it works awesome!
