(Guess this could > give you a sort of poor-man's second-blind sync...) nothing so complicated! all these shots were taken using the following technique: meter for ambient light @ f/11 or f/16 or whatever stop you want to use for your desired DOF. In the case of f/16 this gives you some ridiculous exposure like 1s. Now back off two stops from this so you are underexposing the ambient light by 2 stops. So you should have a working exposure of 1/4 or 1/8 second. Now set your flash to 'auto' for the stop you are using, say f/16. er, that's it! I tend to finesse this depending on the situation. I might only underexpose the ambient light by 1 stop if this allows me to use a shutter speed of 1/15 or less. Or I might do what Rob Appleby does and pretend that the film is rated one stop faster than it is, ie pretend I am shooting with 800 when really I am shooting 400, then meter normally but have both flash and ambient exposures, so the film gets effectively 2 equal lots of light. I think he explained this more clearly than I just did! > > I have to figure some of this out, before I take to the streets of New York > with my Super Speed Graphic and Star Wars flash unit.
