By the way, what does:
I'm a big fan of slow shutters with 2nd curtain flash.
mean, exactly?
I'm completely new and oblivious to all things to with flash but
I'd like to take pictures like the one that accompanied that
sentence.
That picture was a half-second exposure with the flash configured
for 2nd curtain sync. Flashes fire for a very brief duration. On
a long exposure, the flash does not light for the entire exposure.
Normally, the flash fires at the beginning of the exposure, once
the shutter is fully open. With 2nd curtain, the flash fires at
the end of the exposure, just before the shutter closes again.
In that picture, and others like it, the foreground subject is
largely in the dark. You've got strong club lights in the
background, however. The long exposure allows one to capture the
dramatic impact of the background club lights and then the flash
comes along at the end and freezes in the foreground.
I shoot a lot of stuff this way. It allows one to get the ambient
glow of the club in the frame yet have a well-defined foreground
subject. If you look at the shots of the DJs taken from within the
booth at Vision, probably 90% of those are taken using this same
technique. The long exposure means you do get motion blur in the
background, although with the club environment that often isn't a
problem as the background is largely dark and won't register anyway
(excluding the club lights, which are swirling around anyway and
you WANT motion in those).
Here's one I like of DJ Tiësto that illustrates this point:
That was .5 seconds with the 14mm lens held inches above the
CDJ-1000, hence the distorted perspective. (I'm also a big fan of
the perspective games you can play with really wide angle lenses.)
The ambient club lights are no-where near as dramatic as they are
in the one of the girl dancing, but still lends a nice glow to the
image, retaining the atmosphere of the club.
