View Full Version : Metering modes

Hi everyone, I'm a little confused about the different metering modes on my Canon A510 and I wondered if anyone could help. There are three different modes...'Evaluate', 'Centre weighted averaging' and 'Spot'. I was really wondering what the difference was between these modes and perhaps examples of when you would use them. Any help would be very much appreciated. Thanks!

hi !
This the different way it uses to get your photo exposure evaluation.
Evaluate : it uses the whole photo area to get a relative exposition (from the darken to the lighten areas)
centerweight : use only the center area to do same.
spot : mesurement on your very center area (auto focus one usually)

the last 2 are usefull when your subject's esposure is very different from the rest of your image..

also, centreweighted measures (roughly) 75%, so you might use it in most cases, it'll give you the right thing. spot metering is highly sensitive (just 1%) so watch out...don't recompose slighlty.
