Moony 11 rule.

Moony 11 rule.

 

The moony 11 rule is a modification of the sunny 16 rule for taking photos of the Moon if you haven’t got a light meter.

The rule is quite easy to remember - if you want to take a photo of the Moon set the aperture to f/11 and set the shutter speed to be as near as possible to the reciprocal (1 / x) the film speed. So if you’re using ISO 100 film, for example, you would set the aperture to f/11 and the shutter speed to 1/100 sec. However, since most cameras don’t have a 1/100 sec setting you would set it to the closest shutter speed, which is 1/90 sec.

This rule works because the light output from moon is simply reflected sunlight.

cf. ISO, light meter, sunny 16 rule.

SUNNY 16 RULE

Категория: Uncategorized, Photography related — technotes @ 5:26 pm

SUNNY 16 RULE

When caught without a meter, one can use the “Sunny 16 Rule” as a guide for exposure. There are two steps to the rule, as outlined below:
STEP 1: Set your shutter speed equal to your film speed.
 
  (i.e., Shutter = Film Speed)
 
  Examples: 1/60 for Velvia rated at ISO 50; 1/125 for TMax rated at ISO 100. Note that in most cases, the shutter speed will NOT EXACTLY EQUAL film speed, but will be set as close as possible to the film speed. It’s simply easier to remember the rule as “Shutter = Film Speed.”
 
STEP 2: Set your aperture equal to f/16 for sunny sky.
 
  What if it’s not sunny?If slightly overcast, open one stop to f/11. If overcast, open two stops to f/8. If deeply overcast, open three stops to f/5.6.

How do I distinguish between slightly overcast, overcast and heavy overcast?

Examine the shadow detail. If shadows are distinct but soft around the edges, then it’s slightly overcast. If shadows are not distinct, but still visible - very soft - then it’s overcast. If there are no shadows at all, then it’s heavy overcast.

The chart below provides a useful summary:
