One evening I went to a restaurant with my friends. I had my Nikon D70 and an SB-26 flash with me. Yes, this old stuff, but it is reliable and good for all kinds of smart lighting. The Strobist web site has a lot to say about the D70 sensor and older Nikon flashes.I keep this combo in my car all the time as a go-around of gear. BTW, SB-26 works very well with the digital camera in the Auto mode.

I wanted to make a few pictures bouncing light off the celling. But, alas, the celling was 15 feet high and not white! The flash did not do a good job filling all that space with enough light and on top of that the bounced light had wired color cast to it! I was hard pressed to come up with a solution. Somehow it dawned on me that in the car I had a tube of Wet Ones antibacterial wipe and the size of the tube is very close to the size of the flash head on the SB-26. I took off the lid and plastic wrapping with printed stuff on it, mounted the tube on the flash head, and voila – I have a bare bulb strobe modifier! It is about 10 inches long and produces light similar to a bare bulb flush head.
Later on I added a couple of adhesive aluminum foil strips on the internal side of the modifier.

This picture shows you the modifier mounted on a SB-28 head. It can also mount on Nikon SB-800 and Nikon SB-900 strobes. I also used it on a Canon 580 EX.

Another source of the canisters – Dollarama Auto Wipes. The wipes are OK, but the canister is what the doctor ordered!
