This was a very quick project due to the availability of a variety of inexpensive boxes available from Otterbox and now Pelican. Their intense competition has given us a lot of interesting housings for small projects such as displays and now a slave flash housing. I purchased a small slave flash for digital cameras from E-Bay. These units are available all over the place now that digital cameras are taking over. The problem with the on camera digital flash is backscatter from suspended particles. This little device allows the main light to be from the side or back reducing the illumination of particles and allowing for more creative lighting. The flash on the digital camera is diffused with a piece of plastic from a milk carton. The camera flash is still strong enough to activate the flash.

The first step was to find a ready made box that would hold the flash. Pelican was way ahead of us on that one. My daughter cut padding to assure that the flash was protected and would not move in the housing. In the above photo you can see it cuddled into its little bed of foam.

The next step was to cut a window in the back of the rubber liner of the box. The window is to allow the light from the camera flash to trigger the slave flash. If your flash has the sensor on the front, this major 5 minute part of the project is not necessary. All the real time in this project was consumed by dropping by a dive shop to pick out the box after getting the flash in the mail. I always enjoy spending a little time in one or more of my favorite dive shops. In our area, we have several shops with great owners.

In this shot you can see the little window. What else is there to say but, remember to carefully clean and grease the seal.

Put one of these together and you become one of many happy flashers.....
