What sort of exposure times would I need for this, please? I'd be shooting at the f8 or f11 mark on either 160 or 400 Portra, exposed at 125 and 320 respectively. The subject matter would be unlit granite buildings and standing stones. I realize exposure will be in the minutes rather than seconds range, but roughly how many?

Thank you.
 
Dang. I knew I should have checked it first. Old site. This guy is an amazing combination of engineer and artist. His white paper was really great. Sorry.
 
It is reckoned that full moon light is about 1/1,000,000 that of bright sun. So 20 stops different.

If you have a SLR with TTL metering off the film, such as the Pentax LX among a few others, your problem is "solved." Reciprocity failure is still a concern, so bracketing is a good idea. I've shot full moonlit shots with my LX successfully, the effect on C 41 film is...strange. Since the LX monitors exposure in real time a passing cloud is of no concern. IRRC my exposure at f4 on ASA 100 film was several minutes; tripod is essential. BTW if you choose to shoot the full moon itself, it is a sunlit object, so the f11 or f16 with "1/the film speed" shutter speed should work pretty well.
I just visited Kit Courter's site, it would seem to give about all you'd need to get started.

GR, glad you mentioned that since I noticed that on one of the sites mentioned you need at least 1/25th -1/30th to stop the moon blurring and did then wonder how this would be possible if the moon is dimmer than the sun by the factor shown i.e. about 18 stops :D

The Moon receives the same light that we do during the day, but its albedo reflects somewhat less than half the light it receives. Therefore instead of Sunny 16 it is more like f/11 or f/8.

Thank you, that's what I was looking for, someone's real life settings :smile: I always use a tripod, even in normal daylight shoots when the shutter speed is a lot faster than the lens's reciprocal focal length.
Edit: just realized you said several minutes, not seven like I initially thought. Ah well, back to the drawing board, haha

Thanks Sirius. Both easy to understand and remember

But 'Mooney 11' describes what to use when the subject is the SURFACE OF THE MOON! But OP wants to have a suggestion of the amount of light falling on a SUBJECT ON EARTH when illuminated by the full moon, " The subject matter would be unlit granite buildings and standing stones."!

OP, see the section "Subject in Moonlight -- Static Chart" for starters. It says ISO 100, f/8 8 min.
Turn that starter setting into ISO 400 to get f/8 2min, or f/4 30sec.

And for that the Jiffy Calculator is a starting point.

Brilliant, thank you for that, a good ball park figure to be going on with and bracket around. Much appreciated.
