not bad.  black card or single exposure?

i prefer black card method, especially with a wider lens and multiple points of explosions.

eg.

Nikon D300 with Sigma 10-20mm f4-5.6
f16, 13s (black card off probably only about 2-3s total) in bulb mode, iso 200, ev-1


it's not a great shot, and it's unedited jpg i think.  i would've preferred a less distorted shot, i might edit it later and see if CS5 can fix the distortion...

very true, i do photo manipulations in some shots when there's an effect i want to achieve, but it's quite tedious when i'm not getting paid for it...  perhaps when the feeling comes~  i very seldomly do collages of multiple-exposures, especially after that whole National Geographic fiasco with the pyramid shot...

btw, that shot above was taken in TST, with easily over 5000 people all around me...  we were forced out of the way by the security guards several times due to one of their lackey's bad judgment in regards to which stairs they want the "VIPs" to use for moving up to the upper level veranda.
