Small Camera Softbox

I've always wanted to reach a special effect in mind for portraits at home or on the move that I was only able to achieve using studio lighting.

Last night, I made a drawing of a softbox that attaches on the small flash and experimented with the different diffusers until I reached the effect I wanted.

(Image settings Camera=ISO 100 - 1/200 - f/2.0. Flash=1/128. Lens=135mm)

When I reached the desired effect, I cut a clean pizza box to the measurements and assembled the softbox (or diffuser). At the end I used a semitransparent paper as the diffuser and rubber-bands to make the softbox stay on the flash head.

I was thinking of painting it black on the outside, but I'm noticing the cardboard material is not as sturdy as I wished. I guess I'll need to assemble a plastic one for durability in the near future.

Here are the drawings if anybody needs them:

I know the drawings are for the Canon Speedlite 550EX, but at least you can get an idea of what I did. Perhaps you can make revision for your own flash. The idea itself is not new, you can find similar products on the net for around $15. But it's fun to make
