Ok, here is: My DIY ring flash.
Salad Bowl, cut a hole in the middle, placed a pineapple tin can, made another square hole for the flash on the side. Made a bracket out of alumium and shaped it in the way shown above. Flash is a Canon 580ex, triggered by a cable.
The diffuser is a piece of plastic folder I had with documents :-)
The tin of pineapple has a piece of aluminium foil around it so it reflects more light. I love the lighting effect this flash produces. I will upload photos soon (When I find my model)
