af 540 fgz trailing curtain question
OK, so I did attend a flash class over the weekend but failed to learn anything which might shed some light on my question so here goes. When I set my 540 flash to do trailing curtain, it flashes twice - I think once at the beginning and once at the end. Is that normal? (because that is not what I learned) What's going on there, if it's normal? Thanks, --skye -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

That means it uses a preflash to set the output rather than quenching the flash when enough light has been output (TTL). The first discharge is a low capacity flash that tells the camera how much output is required for correct exposure. The second discharge is the actual exposure.

thanks William! I'll have to make some time to play with the settings and I'll return with more questions I'm sure. :) I wish the class would have been more helpful, but at least I have all you guys.
