ok I guess I actually use the s-flash setting on my camera, which my camera explains as a setting that brightens the background. Sometimes body parts are blurry. that photos was taken with my camera by a guy i was giving a lightshow (yea it's me in late january) so he was very close to me, that may be why. Though, in retrospect, I realize that might actually be taken on auto-flash or detect red-eye-flash (which flashes twice and is a bit weird).
s-flash is my 'rave flash' normally. It varies a lot. from friday:
