Not directly relevant, but I'm reminded of something I found in a newsgroup
posting a year or two ago. The question was how to expose under full
moonlight. The answer alluded to the well-known "Sunny-f16" rule for full
sunlight, [where one sets f16 and a shutter speed equivalent to 1/ the film
speed (e.g 1/125 for ISO125)] and defined in its place the "Looney-f4
rule". Set f4, and use a shutter speed equivalent to 1/ the film speed in
*days*. So for ISO100, you'd use 1/100 of a day, or fifteen minutes :-)
Of course, our OM-2 and OM-4 would get it right on auto... (OM content!)
