    Question XTi/400D Metering

    Hey--

    I was reading about using spot metering, which the XTi/400D doesn't have. Which is most like spot metering: partial metering or center-weighted average metering?

    Thanks

    Thanks Forno--that would be center-weighted average. But from the manual's illustration on page 73, it appears that partial metering is more like spot. My confusion stems from the fact that the text accompanying the illustrations isn't clear at all.

    AdamW,
    First, I am no expert. But I have found on my XTi I get the best results (closest to spot?) from partial.
    I have tried it repeatedly in all 3 modes using the exact same subject: ie: towards the sky, shooting a bird on a limb.
    The best results I have seen comes from partial metering. The subject is most naturally lighted and the bg is not as bright. And I using ONLY the center AF point.
    Don't know if this helps any because I have never used a spot metering camera yet.
    Give it a try and see what you think.
    Oh, and you are very correct in that the manual is really vague in a description of the different modes. However, it did make me want to experiment.
    Hope this helps,
    Ron

    Thanks, Ron. It's reassuring to hear that you think the text is vague--it makes me feel slightly less dense. I think you're right, and I will experiment. And I already use only the center AF point. I like to focus and recompose beacuse I hate it when the camera decides for me what should be in focus.

    Thanks, Michael. That site has a nice review of stuff I learned and then forgot. So the answer to my original question is that "partial" metering on the XTi is like "spot," only with a bigger spot.

    Partial metering is the closest you wil get to spot metering on the xti, 9% if I can remember correctly

    Correct, 3% on the 30D, 9% on the XTi. Really, both are in fact "spot" metering, but Canon calls it partial on the XTi to make their more expensive models sound better. The real world difference between a 3% and a 9% spot meter is a lot less than most people think.

    Well, seeing that 9% is a pretty small spot, I'll just tell myself that I've basically got spot metering by a different name, and use that. Time to move on and learn how to use that spot....
