sorry, the flash to subject distance was around 18". GN30m flash at 1/16th. I tried to set the shutter at the highest speed so that only flash light made the exposure. I must admit, I did not do the maths, being excited about finally getting to do some shooting! After some quick calculations on the back of an envelope, looks like 0.5m (about 18") at F16 with 3000asa film, is equivalent to the settings I made.
