metering system

16th June 2003

Hi all,
can anyone explain the difference between
evaluative
partial
centre-weighted metering

for canon system?

Which kind of metering is recommended for which situation? Canon has no spot metering right? then what is the equivalent of spot meter?

One last question, if i want to meter manually, like for a building or face or edge of cloud and during black and white phototaking,

which metering system should i use.

Thanks in advance, Sorry for the numerous questions!

the pro EOS cameras have spot metering - 1D, 1Ds, 1V, 1N, 1, 3 and 5

if you already have a canon camera, just read up the relevant section in your manual, it's all there.

It'll tell u which part and how much of the frame the metering is done and from there you can infer from your shooting style when to use what kind of metering.

For lower/mid end Canon cameras, the closest to spot metering is partial metering. Partial metering works the same way, except the coverage area is bigger. Most of the time it is quite sufficient.

So for your question, if you want to metering one specific area or part, use partial metering.

I've tried to read it but i can't quite differential between partial (10%) and centre weighted (which is weighted at the centre and averaged for the entire screen)??!!!

doesn't say which area to use to focus... view finder also don't have circle for centre weighted.

Any help? thanks

The partial meter area for the Eos300 (7 AF pts) is within the center 5 AFpts' Parameter.

You'll see its effect. Meter a dark tone object with a white background, filling the 5 AF PTs' with just the dark object. Set your camera to manual, press the * button for partial metering, then press the shutter release half way for the cw metering.

The partial metering should suggest a slower shutter speed relative to the cw if both are set to the same aperture.
