Well, that should not be too surprising. You'll hear this said over and over again (may already have been said in this thread) but remember what the meter is trying to do: It's surveying ALL of the levels of brightness in the scene and then trying to set the exposure for the shot so that everything comes out a middle gray - neither bright nor dark. If you ask the meter how to shoot a bright sky, the meter will give you settings that make the sky too dark. If you ask the meter how to shoot a big pile of coal, the meter will make the coal too light. Now, shoot in a darkish room with a couple of table or floor lights or candles and the meter will suggest settings that lighten up the shadows - and blow the highlights from the lamps.
That's why you either have to learn to shoot Manual OR learn how to use exposure compensation (with the +/- button) to bias the meter one way or the other.
Quote: How do I set an exposure that'll capture the actual light levels? Before someone says, 'switch to manual...' I'm meaning what are rules of thumb (if any) or how should i use the spot meter or histogram so that I can get my first or second shot closer to what I want?
Well, this is where it gets tricky. DO NOT LET THE HISTOGRAM DICTATE YOUR EXPOSURE SETTINGS. Don't let the instant review of the shot dictate the settings either. You want to expose the shot that you get as much as possible of the data on the right side of the histogram, because those are the areas where your camera's sensor is most discriminating. If you do this correctly, in some cases where the dynamic range of the photo isn't very large, the result will look TOO BRIGHT when you view it immediately after capture on the camera's back panel. That's okay, so long as you didn't blow highlights. You can darken it up in post processing. This is an annoying, occasional requirement of digital photography. Not necessary if you are shooting film.
I don't know any rules of thumb. What I do know comes from experience, lots of experience shooting in low light. I walk into a church knowing from experience that I can set my camera to f/2.8, ISO 800 or 1100, and hope to get a shutter speed of around 1/60th sec. I set those settings, point the camera at a scene, and look at what the meter says. I don't just let the meter dictate my settings, because I have to look at the scene with my own eyes and try to decide what the meter is responding to. I've shot in rooms where the walls were mainly all glass, so there was lots of light coming in through the glass walls - meaning the indoors subject was strongly backlit. In such a situation the camera's meter is going to try to darken the scene up. The meter is responding to all that light coming in through the windows. But I want to make sure I expose properly for the person I'm trying to photograph and I don't care so much about the windows. So I very well may use settings that the camera thinks result in overexposure. That's okay. I may not mind blowing the bright windows out - might even like the effect - if the subject is nicely exposed.
Quote: As Mark S suggested earlier, in manual, press green button to get recommended shutter speed after selecting f & ISO but where to from there?
Well, you can put the camera's metering option to spot metering, and make sure you get the meting point right on some part of the subject that is critical to your exposure before you hit the green button. But I don't recommend using spot metering too much. I use full matrix metering nearly all the time. You just have to learn to look at the scene with your own eyes and think about it. To keep bright scenes bright, push the exposure a bit to the "right", that is, overexpose. You may have heard people say that you use an exposure compensation (EC) of +1 or even +2 when photographing snow.
Get familiar with the basic concepts, like how your meter wants to make everything middle gray. Then practice. Take test shots, look at the results and think about 'em.
