Looked good to me (but what do I know)

However, on your pic http://www.pbase.com/bret/image/34120290, you really do
need to see about getting those hot pixels mapped out...

they will be somewhere else when the 2nd curtain

2. it feels better when the flash gets of when you
push the button.

3. Using rear-curtain sync, you are effectively introducing the equivalent
of "shutter lag" nearly equal to the exposure time.

Thanks for the info. I can now see why you would want 2nd curtain
synch. I'm just a bit afraid to ask why anyone would then want 1st
curtain as well! Ducks for cover.............

Given that shutter speed for flash sync is typically 1/125 can you
notice a delay of 80ms? Obviously if you need a logger exposure for the
background, but there are then good reasons not to risk startling your
subject with the flash when the shutter is will remain open long enough
to record their reaction. If speed trails are an issue then any reaction
to the flash will be a small modification of existing movement.

Which could be 80ms, or less.

Or it could be a whole lot longer. So? It's a reason to use front-curtain
sync, not some kind of silly argument that you should always use it.

1/250 could have been a crispy 1/350 or more at 2.8,
and yes...you'd still have some obvious and nice motion effects...

Can you say "flash sync?"

Should have bought a D70 then. ;-) (ducks and runs for cover)

NB. I like your images.
