If 1/15th sec.shutter at ISO 400 is a certain exposure, what would be the equivalent ISO values at the following shutter speeds?
1/30th - ?
1/60th - ?
Thanks, trying to figure out my limitations on flash shooting and where to set it's upper limits on Auto-ISO. I would like to shoot ISO 800 but I don't want to deal with the noise.
