We used the “Kodak rule” to set exposures. We’d set the shutter speed to match the ASA (now ISO) number of the film and the exposures, as I recall, would be: F16 – bright sun F11 – hazy sun – ½ the light of bright sunlight F8 – cloudy bright – ¼ the light of bright sunlight F5.6 – cloudy regular – 1/8 the light of bright sunlight F5.6 and drop a shutter speed – German* cloudy days in the winter F5.6 and drop two shutter speeds – dark German cloudy days in the winter F5.6 and drop three shutter speeds – on the edge of the woods on a dark German cloudy day in the winter F5.6 and drop five shutter speeds – in the woods on a dark German cloudy day in the winter (with the camera braced against the tree as a makeshift tripod substitute (but I got the picture and the trip was not lost). If your solar charger has the capacity, it should keep charging on cloudy days. (A solar electric fence charger was probably designed and built with that extra capacity in mind.) *Germany is farther north. Our area was farther north than the U.S. / Canadian border.
