ST-E2 and 2nd Curtain Question

It's main use in getting the flash trail effect with moving objects at night or similar type of situations.

If one is shooting a long shutter of a passing car, say 1/4 sec, then the flash illuminates first and make the car look as if it is going backwards.

If one uses second curtain sync the flash is at the end of the exposure and the flash trail is going the right way making the car look like it is going forward.

I understand what it is...

Canon really needs to find a way to allow wireless 2nd curtain sync... That would be my default setting.

... but this guy doesn't (no offence intended). I don't think many people do. It's mostly n00bs that go on about 2nd curtain, without realising it's useful in an extremely limited set of circumstances.

I agree. Most people describing the effects of 2nd curtain sync are actually describing an image that would look the same if they synced with the first curtain.

Some even use 2nd curtain sync at 1/60 s and think they achieve something, without knowing that Canon's cameras default to 1st curtain already at 1/30 s.
