My version on the DIY diffuser is based on the film canister idea but instead I used a travel toothbrush container I picked up at Walmart for 97 cents. I wanted to make mine where it wouldn't stand out as something other than what I meant it to be. It slides on easily from the side, is firmly seated in the front by a little groove under the flash and remains stable during use. In the picture you can see how it attaches as well as the with and with-out results. With the diffuser, you see the wall paint the correct color. It also works well with portraits.
