I've finally got it so that my on board flash is firing my SB600 but now I'm getting a little annoyed. I want it so that the onboard flash doesn't fire but still signals my strobe. I also want to be able to control my strobe in the manual mode rather than having to do it on camera. I'd rather just walk up to my flash and decrease/increase the power than have to fidget with my camera. Can this be done or is this something I have to get used to now? Thanks for any help!
