D70 Metering function

[Joe N.M]

Hi all,

I owned a D70 and I am quite new with it. I would like to learn about the 3 metering functions that D70 offers and its differences.

Can anyone help me to explain further about it or is there any website that explains all.

Thank you.

Yeah, the manual actually explains how each of the metering works, try reading that first.

The 3 metering modes all work in the same way - they determine the "correct" exposure settings by measuring the strength of the lighting from the subject. The difference lies in the area used to measure this light:

Spot-metering measures only the light from the "spot" in the middle of the frame.

Centre-weighted measures the light in the centre circle (roughly) of the frame.

Matrix takes into account the full frame and also is "intelligent" to determine ideal settings for the composition (eg a people in a landscape, portrait, etc).

As an example, if you take a shot of the moon and the moon is not very big in the frame, using matrix metering will tend to lead to moon being burned out as the large areas of night sky will cause the camera to over expose. to capture the full detail of the moon, it'd probably best to use spot metering (with the centre spot on the moon). if the moon is big enough to cover the centre circle, centre weighted should work as well.

Then there's stuff like exposure lock etc - read the manual.

Hope this has been helpful rather than more confusing!

Actually,

spot takes the reading where you selected the focusing point, not only center

Matrix takes up to 75% of the frame, not the entire frame

Hi TimLim and Espn...ur explanation really helps. It gives me a rough idea of how the metering will work. Thanks.

Thanks espn, my answers are always only 70% correct! Should have referred to the manual myself!
