Easy & Cheap Flash Diffuser

Intro: Easy & Cheap Flash Diffuser

This is an instructable for an easy and cheap flash diffuser for the on-board flash of most SLR camera's.

Step 1: Project Box

The item I used for my diffuser was a cheap $3.00 project box, obtained from a local Radio Shack. I removed the 9v battery compartment lid, took out the screws and cut out a larger area as shown below.

Step 2: Diffusion

For the diffusion material I cut a properly shaped piece out of a 4litre water jug. and replaced the open end piece of the project box with it.

Step 3: Putting It on the Camera

Simply slide the box over the top of the on-board flash (while it is open) and if you cut it right, it should hold in place over the back of the HOT SHOE.

All Done, it looks oddly familiar.......

Step 4: Testing It Out

Putting it to the test... I would say it's a success.

    A good idea. Well done. I would add +1 stop compensation as it looks like you've lost a bit of light.

    Normal light from a bulb is harsh, and often gives hard shadows that don't look good. When it's spread out, it looks more natural.

    Hey! Very well done! 4 stars! Will this work on a camera that doesn't have a pop-up flash (like mine)?

    I do not know, you would have to measure it out yourself. This version requires a pop-up flash. Thanks for the comments!
