I used this theory to start with, (the difference between f-stops = number of flashes) but i found it to be insufficient. i found that i got good results from multiplying the difference by 1.5. (So; exposure = the difference of meter reading and camera aperture x 1.5)
EG; meter = f-64, camera = f-283 'pops' = 18.
and also soft boxes are not good you need directed undiffused light this seems to work better. I have to run a workshop on my theories as part of my course so i will get back on the flash formula, and see if it accurate for more than just my camera.
thanks for the replys, i'll check out the archives ;)

You need to meter the flash, obtain the f stop that will give good exposure with the flash placed where it is, then calculate how much smaller your aperture is than the aperture you obtained by metering, then flash it that many times. If the pinhole is 1/50 the area of the metered aperture, you will need to flash 50 times to get the same exposure. On the other hand, pinhole is about play, so just play with it. Try hoding the flash close to areas you want to emphasize, further fronm the shadow areas, and do trials tom see how many flashes you need. there's some abut flash in Eric Renners book also.

I used flash until I dropped the unit = and broke the=20 bulb. You need to meter the flash, obtain the f stop that will give good = exposure with the flash placed where it is, then calculate how much = smaller your=20 aperture is than the aperture you obtained by metering, then flash = it that=20 many times. If the pinhole is 1/50 the area of the metered aperture, you = will=20 need to flash 50 times to get the same exposure. On the other hand, = pinhole=20 is about play, so just play with it. Try hoding the flash close to areas = you=20 want to emphasize, further fronm the shadow areas, and do trials tom see = how=20 many flashes you need. there's some abut flash in Eric Renners book = also. =20 From: Jarrard

Thanks.
