"rear curtain" synch is when the flash is triggered just before the second curtain of the focal-plane shutter starts to close (normally the flash is triggered as soon as the first curtain is fully open). (If you happen not to know how a focal plane shutter works I'm sure the net is full of articles with nice illustrations and such.) So "rear curtain" means that the moving subject is frozen at the *end* of their travels during the exposure (which is almost always what you want for this kind of shot). As I just mentioned to Andy, I remember my camera (Nikon D200) manual as having a note that rear-curtain synch doesn't work with studio flash. I don't have the book here to give any more detail. And it makes no sense to me. Which is why I remember it so clearly. So you'd better do some tests ASAP to make sure you know what works with *your* setup. -- David Dyer-Bennet, dd-b@xxxxxxxx; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
