Gel Mods and Cheap Slave Flashes

A while back I mentioned a simple 15 minute light tent, that could be used as a makeshift studio for product shots and other small things. One of the great things about that setup is that you don't necessarily need to have slave flash units to use it, but Dave Pearson shows us how we can use the (very reasonably priced) Quantaray MS-1 flash boosters as the external light source. These things fire when they see another flash, so you don't need to trigger them with some other tool. It's all automagically taken care of for you. Dave's article talks about how to modify them to use gels to get some special effects, and is well worth a look at. His article also mentions Strobist's $10 Macro Studio, which is similar to the 15 minute light tent.
