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 ;)

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
