correct exposure...

[thenimirra]

does your camera indicate to you when you have a correct exposure? some of the books I've been reading says the camera will "let you know" when the exposure is correct (ie, the correct shutter speed, ISO and aperture).

What is that indicator? Does something flash on the camera's display?

A correct exposure? I don't see how that could be very valuable as I doubt any camera can predict "what looks the best." It would have to judge noise, light, depth of field, white balance, and what you're actually trying to convey (IE; If you're trying to shoot a waterfall that looks streaming or stopped)

The only thing I can think of that's close to that is the light meter bar on a lot of cameras. I know that's not the exposure but that's all I can think of that would let you know if the picture is "good" or "not," ya know?

The book is "Understanding Exposure." The author, Bryan Peterson, keeps refering to "correct exposure," as if something inside the camera will tell you when the exposure is correct. You have to keep changing your settings, or "metering off" things before the camera registers it's correct. I don't really understand what he is talking about.

Oooooooh that makes more sense. Basically what he is probably trying to convey through "correct exposure" is a photo that is not underexposed or overexposed. Though regardless of this meaning he's trying to point out, it can sometimes be the "wrong exposure" if you're doing black and white photography where you get a more wow-effect if it's slightly overexposed.

Does it explain the 3 common types of metering? By "metering off" he is maybe referring to spot-metering. :shrug:

[thenimirra]

no, he doesn't explain, metering, or at least, he hasn't yet (since I've only studied the first couple of chapters). :P
