Guillermo, With your info i got off your website, the sunny16 + iso exposure rule, when using a meter do you use the meter reading and the iso=shutterspeed to calculate your exposure?
I used it to teach a class but had varying results, although i have suspitions that the cameras were dodgy. I just need a little clarification on this. But the ones that did turn out on my camera and one other were as near perfect as i could have hoped. Also if you have any info on Pinhole under studio flash conditions i would really appretiate it, i had a formula worked out which worked well for my camera but had limited success with the others. I used exposure = difference of stops from meter reading to camera aperture x 1.5 If you have any suggestions to improve this, that would be great. Thanks :)
