Before I go on, sorry about the awful editing. I wasn't trying to make this look nice, I was just trying to get rid of background distractions -- I also happened to like the look of "Cutout". I'll probably upload a nicer picture showing how the flash is set up, as it's not too easy to see in this one.
Cowboy Studio Wireless Transmitter
Fotodiox Soft Box
DSLR 300 Flash
Neewer Flash Bracket (taken from the slave flash unit)
Canon MP-E 65mm 1-5x Lens
At the moment if I extend the lens all the way out, the flash will not be able to reach the subject. I plan on eventually purchasing a mini ball head that I could configure to give my flash more mobility, but until then, this set up will work just great.
