I'm afraid that wasn't much help. It should have been though, if I was any good at this sort of thing!
I went into my camera's manual mode, and set the ISO to 100, but then came the bit about adjusting the aperture to get a decent shutter speed. Well as far as I could tell, I had to manually set both aperture and shutter speed, the speed did not change automatically in response to changing the f-stop. Quite frankly it is all a bit beyond me.
Any one else able to help? Or, how about someone nice in the UK lends me their light meter for a week! I have looked on-line, but they are all either vintage collector's items, or a bit expensive for me.
Just want to cry now.....
