Talk:Looney 11 rule

The information on this page is in direct contradiction with its sources:

http://mkaz.com/photography/exposures-for-moonlight-photography and http://mkaz.com/photo/tools/expcalc.html

Both list exposure times to be 8minutes+ not. The current version of the page has it at 1/ISO !!

Lunar versus Moonlight

Half of the sources referenced were talking about Lunar photography and the other half were talking about moonlight photography.

I always used the sunny 16 rule settings for telephoto shots of the moon, but the Albedo page does list the moon 0.12 as darker than the earth .3 to .35, so I assume opening up one stop might make sense.

The ISO ratings on the Cannon Ti4 DSLR I just bought seemed so out of line with the ASA 400 Tri-X I used to consider high speed, that I had to double check by reading Film speed.

That lead me to Sunny 16 rule which led me to Looney 11 rule which led me to http://xkcd.com/386/

I can't comment on the usage of "Looney 11 rule" as I don't recall ever hearing that phrase before today. I just hacked the old write up into two pieces such that neither grossly violates the laws of physics. SteveGoncalo (talk) 04:33, 3 February 2013 (UTC)

the albedo of the Moon's surface material is lower (darker) than that of the earth's surface

the albedo of the Moon's surface material is lower (darker) than that of the earth's surface may be true, but the sunny 16 rule is based on the reflectance of average subjects, which is 18%. I suppose the earth is an average subject, but that isn't what the rule is based on. (That is, very few people take pictures of earth, but of people, trees, lakes, and such. I suspect that mud is darker, and dry dirt lighter, and sand even lighter. Gah4 (talk) 00:37, 24 March 2018 (UTC)

The Moon's albedo is 13.6% - somewhat close to 1 stop darker than the 18%. Bubba73 ^{You talkin' to me?} 04:23, 24 December 2018 (UTC)
