Originally posted by Stardog For some reason I am still somewhat confused regarding metering. I understand the concept, just not how to properly or effectively use the settings.
After buying my K-x late last year I took a beginner's digital photography class.
this can be a good thing, and aside from anything else exposes you to one professional's view point, however he may not explain fully the theory behind the approach he uses
Quote: The instructor, a well-published professional photographer, mentioned that the easiest way to meter if time is of the essence (and all other things being equal) is to set the camera to spot metering, aim the camera at the whitest area of the scene, partially depress the shutter button to capture that spot, then re-frame and shoot (my camera is set to the default exposure metering of 10 sec., which allows me plenty of time to do this).
here is where the theory breaks down, this approach will result in you under exposing by several stops all the time because white is supposed to be bright, but the camera's metering will try to interpret this as mid grey

just I can't figure out any instance where I would do this

The more I research metering, however, the more I find users recommending multi-segment metering as the default for most shots, and adjusting to spot or center weighted in extreme or problematic lighting situations.
multi segment can be pretty good, especially on the K7 and K5 which have evolved away from the 11 segment pattern pentax had used, to a 77 segment pattern

Question 1: All things being equal and I am shooting outdoor scenes in daytime with good lighting, what is the preferred metering method?
there is no preferred, multi segment will work well if you are not overly concerned about possible loss of some highlight or shadow detail, especially in high contrast scenes. If you are concerned about one specific point being perfect, then set the meter to spot, and meter on that point (kind of like the pro told you) but also consider, the appearance of that point, relitive to a mid grey surface, add or subtract a stop or so, depending if you think it should be lighter or darker than mid grey

Question 2: If I am shooting indoors in less well lighted environments, how should I meter this?
no differently than in 1 above

The more I think I've learned, the more it is that I seem confused about...
The way I meter, especially in outdoor situations is to often find a mid grey surface (i.e. a substuitute for a 18% grey card) and meter off that. Roads, or tree trunks work very well for this. Then I use that setting as long as the lighting does not change.
I hope this helps.
