It's a simple process... I time synch all my cameras with my PC, and then in Bridge I arrange them by date shot, it sorts them automatically for me, and then I batch rename them with a new sequence number once I've done my first cull. This way, when the image gets printed, and the file names on the back stay sequential. I've been asked once, what happened to file numbers such and such, when there was a sizable gap in between them.

(yea, I know... I didn't say that up front)
