This has no doubt been covered somewhere but I couldnt find it.

My Canon 400D has 3 choices, none of which I really understand.

Evaluative, Partial and Center weighted.

Every time I set up the metering for what I think it should be, the little red dots don't flash where I think they should.

Be gentle with me, I'm blonde.

Evaluative takes consideration of your whole viewfinder's frame.

Partial, I believe this is what 'spot metering' is, and it takes consideration of only a very small spot of the centre of your viewfinder.

Centre weighted takes consideration of the circle in the middle of your viewfinder.

What metering does is take light metering of that particular area described above and will work out on an exposure according to the light it sees. It will try to balance things out and take the photo with an exposure that the camera thinks it is right.

The red dots/squares should only be autofocusing points, and nothing to do with metering. Your camera's manual should have enough detail on how these works.

Hmm ok maybe my question came out a little less clear than I intended it to

Thanks though Y-ip.
