How do I do it? Is it even possible in my camera? I'm using a Pentax DL. I can't find any way to override this STUPID pre-flash!! Which means the AC slave and $300 dollar flash I bought are pretty much useless right now. Unless I use the B setting and trigger the slaves myself!! How can I shoot living things like that?? If there's no way to override this pre-flash, are there any alternatives so that I can still use the slaves?
