Understood. But when you have to have groups of 3-5 students shooting at once and only one radio trigger, well, optical triggering it is. >But you have at least two possible issues with each student's camera: the >x-TTL pre-flash, and the "red eye reduction" pre-flash. Either or both of >these might be enabled in any given camera. I did check to make sure red-eye reduction was turned off. I didn't see any options for turning off X-TTL pre-flash. I may have missed it (we had a lot of different cameras, obviously) or it may not have been an option in the very cheap DSLRs the students had. >BTW, most PCB strobes come with a really long old-school PC-Sync cable. >That might have helped with any of the students cameras that have a sync >socket. Sync socket? Har! Not on any of the cameras here. I'm genuinely surprised they all had manual exposure as an option. -- Mark Roberts - Photography & Multimedia www.robertstech.com -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
