recently got the 120w lights from eastgear and I am having some problem taking photographs with my 300d.
I am using the built in flash to trigger off the studio flash, but about 90% of the time, the shots are underexposed. I used a piece of negative to block off most of the light from the pop-up flash, leaving sufficient enough to trigger the studio flash.
Initially, I thought it was the sync speed but i reconfirmed that I set it to 1/125s and took with various F setting, but this still didnt work.
On closer examination, I realised that the 300d fires a pre-flash before the main one and this triggers of the studio flash... effective "flashing" even before my stutter opens.. ~sigh I think this is the cause...
so (after all the above gibberish...), can someone kindly advise on the next step?
1) get a PC-sync thingee to attach to the hot-shoe and connect to the flash?... wires get in the way though...
2) get a IR trigger to attac to the hot-shoe? which IR trigger and how much is one?
3) somehow eliminate the preflash on the 300D... (ideal ..cuz no need extra $$.. and broke from buyin the lights... )
