flash diffuser

I've been cutting up plastic milk containers to make flash diffusers - the Gary Fong looks great but seems expensive for a bit of plastic. I wanted to throw some diffused light forward and also get plenty of widely diffused light from the ceiling as well. I marked up a 3 litre and 2 litre bottle as shown in the picture, then cut round the line to make a kind of clamshell shape, with a tail that will slip through a couple of rubber bands on the flash head.

 

The picture shows the fixing.

 

I rotate the upright flash head through 90 degrees, so that when the camera is used vertical, the head can just be folded up to the new position.
