Exposure

[jcdeboever]

What are some scenarios that would warrant a decision to under expose or over expose in camera using digital or film? Hopefully this is not too generic of a question.

I never want that. Maybe I am not clear. There are buttons or dials on my camera, I assume they are there for a purpose. Also, Hedgecoe book mentions it (film) but does not go into detail about it. My manuals are not helpful.

Underexpose: a) Failure to bring a tripod. b) Moving subject.
Overexpose: Never.

You're about to get into a convoluted discussion about what is correct exposure. What do you mean by underexpose and overexpose and relative to what definition of correct exposure?

Just curious as to why it is available and why would I need this feature.

Cameras have an EC (exposure compensation) button or dial that permits you to set a correct exposure in circumstances where the camera's internal metering system would under or over expose.

which buttons/dials are you talking about?
theres a few of those on my camera. maybe more on yours.

That's lighting not exposure. You still set a correct exposure in high and low key lighting.

oooooh yea...
its probably that.

it has to do with the way the camera meters, what metering mode you are using, and if spot metering what area you are metering for -vs- the exposure of the remaining area.
there are plenty on the forum far better suited to explaining it than I am. I dont use EC very much on camera.

Oh, I see. I was using wrong terminology. It is EC. Now I can search forum for details. Thank you all.

What are some scenarios that would warrant a decision to under expose or over expose in camera using digital or film?

In the olden days of film, it was said that you should "expose for the shadows", meaning; make sure you get some usable image in the shaded parts of the frame.

With digital, if you blow out the highlights, you are left with no data in the highlights, so I would rather underexpose a bit with digital. (average scenes)

For shooting random scenes with a digital camera, you can take meter readings off the highlights, and work toward the shadows, bracketing a few shots.

If it's a dark scene, meter the most important parts.

For very bright scenes you would want to underexpose, particularly if you are using "averaging" metering because the meter will attempt to expose for an average scene, and it will end up way too bright, often blowing the highlights.

Unless I'm wrong.

Excellent, thanks. OK, now what Hedgecoe was talking about is making more sense. Appreciate it. Very hard to articulate when I don't have a clear understanding of the whole exposure triangle and various metering modes in cameras.
