I'm playing with some old flash guns

Other than milk cartons does anyone have bright ideas (prefereably very cheap) for material for these?

I guess this has been discussed before

Also any "clever" designs etc

Just remember that the whole aim of a diffuser is to increase the area of the source of the illumination. Just covering the flash window with some white plastic will make no difference. Even if you use a Stofen diffuser or the standard diffuser that comes with the FL-50R, without walls and a ceiling or other large surface to reflect the light spread by the diffuser onto the subject, it's useless. I'm sure many of you have seen professional photographers outside (whether at night or during the day) with small diffusers fitted to their flash units, often pointing at the sky - the diffuser is certainly doing something, but not what the photographer needs. All it does in such situations is to reduce the effective power of the flash! It does nothing to soften the light. Even with a small diffuser fitted, the flash remains a point source of light that will throw sharp shadows.

I reviewed a commercial solution that works well on DPNow a while ago. The sample images compare the effects of various flash configurations. You might find this useful:

Quite right Ian.

My main problem is my old flash gives none adjustable full power
Sometime I just need a bit of soft fill in light
I've had a bit of success aiming the flash at a reflector and catching the bounced light.

Anyway since starting this thread I've had a bit of a google
There are lots!
This one particually caught my eye.

All I need to do now is pluck up the courage to visit IKEA :eek:
Actually I DO need a few more pencils:D

Yes, as Ian says, the idea is to make the flash seem larger from the point of view of the subject.

My cheapskate method is to use some matt mylar film (rather like indistructable paper sheet) folded to fit the flash with velcro...


However this is not really big enough. Fairly soon I will have to buy a shoot through white umbrella..
