Here's one of mine: Shot in my basement. I don't know what type of flower this is, it was growing my neighbor's yard.
I posted it in the flash forum for feedback there. Shot it with my 20d is 800 and my sigma 70-200. Used my yonugo 460 at 1/8th or 1/4 power if I remember correctly.
EDIT: warning I think it's in adobergb so use Firefox or something else with color-management, I made most of the jpgs into adobergb from this shoot since the colors were a little too intense for sRGB
EDIT: actually it seems that smugmug automatically attaches sRGB profile to it's downsized images, not sure if it even converts or just assigns
