Randy,
I was a wannabe pro. Started in darkroom stuff when I was 10 and dabbled in and out of it taking college classes building a darkroom. Eventually lost interest and went on with life. Been away from it for a long time and just started dabbling again with digital. The mirror thing was an adhoc way to save building bulky diffusion lighting with stands and all that conventional stuff. Since I bought the Nikon D50 and a SB800 flash and remote cord I can do more than the mirror technique will allow. But honestly, the mirror technique is more convenient once you get used to it.
