Dirt cheap diffuser

Hi all,

I'm planning to get myself a good quality external flash in a few months but in the meantime I'm looking to make the most of the built-in flash on the K7.

I've had a crack at all sorts of home-made solutions with varying levels of success (the 45 degree business card worked the best indoors). But it would be nice to have some kind of simple diffuser that would stay on when I'm outside in the wind.

I've found this on eBay:

3-1-Puff-Pop-up-Flash-Diffuser-Fr-Pentax-K-7-K-X-K-m

Has anyone had any experience with these? It's only a few dollars so I'll probably just give it a crack regardless unless someone has used one and found it does absolutely nothing.

I do not have personal experience with these but have heard they are pretty good and for the $ you cannot go wrong.

A free option is to find/get a white (clear/almost see through) film canister, cut out a rectangle (measure the pop-up flash for the exact dimensions) and put the canister over the flash. This is what I do with my flash and it works really well.

I've heard of people using those. I've heard they work well. Never used one myself, like KxBlaze.

To diffuse light WELL, the best way is to make the light source bigger. You can shoot through a diffusion material like this device, but the best way is to bounce it off a wall or ceiling (short of using a softbox).

Cost: free.

Or if you're outside, use the sun. A few white foamcore boards to bounce light up from the sun to the subject work extremely well. Black foamcore works well to reduce light.

Thanks for the tips guys.

The old film canister trick sounds more wind friendly than my attempts but I can't say I've bought film any time in the last 10 years... So I might give this cheap diffuser a crack.

Another cheap trick:

Use the thinnest infant's sock you can find. Or a translucent condom.

Would the one with ribs give you an uneven illumination?. Or could it be used for creative lighting effects?.

Hmmm, I haven't kept up with condom technology lately. How about translucent models with faces? Back in the day, were Dick Nixon rubbers... but they were opaque.

I have one of these, it works well but it really decreases the flash's power, which is already not very much, so it is very limited in use.
I don't have any use for the different colors either.

Not sure about the uneven lighting, but if there are two flashes involved, it may trigger the other one more reliably.

several tricks to consider....you can cut a ping-pong ball to fit over the pop-up flash like a "Smelfin" type, you can cover the flash with a coffee filter, you can cut out a bounce from card stock and covered in smooth tin foil and attached at a 45 degree angle (FinnBounce), rolling paper over flash, etc...never used a condom though.

The FinnBounce and the Smelfen

Take one pair Sheer Energy white hose and one rubber band. Cut toe off one leg of hose and secure over the flash with the rubber band. Instant diffuser.

Warning for the guys: Do not use your wife's new pair of of white hose. She will not be any happier with you than my wife was with me.

I got one JUST like this from Ebay, except without the blue and orange filters. I got it just because i was to take some photos of the family this coming thanksgiving and christmas and i dont have a regular flash and/or a diffuser/deflector. It makes the flash marginally softer, enough that i can use the pop-up flash for family photos in darker rooms.

Ah, I made a cardboard thing with foil on it just like the finbounce. Works pretty well.
