This cardboard ringflash is made for Canon EOS models with build in flash. It was build around a 1000D but also fits a 500d and 550d. The special things about this ringflash is that you can build it fast with simple materials but also you can take it apart and have it flat inside a briefcase. I actually shot an event using this and fell in love with the nice soft lighting and almost shadow less look. I might even consider buying a ringflash instead of a normal flash.

The best material to make it is a 300grams cardboard with one side black and otherside white. And have the inside white so that the flash would diffuse the white, while the blackside actually makes light only to come from the ring so you would see more of a ring shape instead of the shape of that ringflash.

Here are few pictures that were taken in Hong Kong at an Event, you can see the nice soft lights while also almost no shadow cast on the background. It looks way more professional than any event photography using normal flash with a diffuser. However using the onboard flash does use more battery and would not advice using it for event photography unless you have allot of batteries or a batterygrip.
