I added illumination use, because light meters are very often used in automatic regulation of lighting.

There is, however, a question of combining different articles related to that: 'PIN diode' or 'light regulation', which is currently, quite unappropriately, redirected to 'Dark-sky movement' article

[edit] Exposure determination with a neutral test card

I added the math to this section in attempt to show the basis for readings obtained with a neutral test card. Almost as this was added, however, it struck me as adding more clutter than utility. Unless someone objects, I'm inclined to remove it. Thoughts? JeffConrad 22:41, 15 October 2006 (UTC)

It's part of the article that people will skim-read, so it's not important. But what does "The instructions also recommend that the test card be held vertically and faced in a direction midway between the Sun and the camera" mean? I cannot picture this in my head. -Ashley Pomeroy 22:41, 16 March 2007 (UTC)

Example: imagine an outdoor scene in which the Sun is 30° to the left of the camera. The Kodak instructions would have the test card held vertically, with the perpendicular to its surface 15° to the left of the camera. In my experience, this doesn't always work as expected. The primary problem seems to be that a typical test card is far from a perfect diffuser, so that specular reflections can sometimes have significant effect on meter readings. But the instructions are what they are, so that is how I described them.

No one has objected to the deletion of the math, so I assume that I probably should not have included it in the first place. JeffConrad 00:24, 17 March 2007 (UTC)

[edit] Style consistency

A minor note: the remainder of the article is in American English, so I think "analog" might be preferable to "analogue". There are far greater issues, though; this article has had many contributors, and it reads as a bit of a hodgepodge. It would benefit considerably from an overall edit.
