Metering

[ast]

hi guys!

just want to ask about metering:


1.) on center-weight metering, if i change the AF area point to right af point, when i meter, should i based it on the center af point?

2.) on spot metering, if i change the AF area point to right af point, when i meter, should i based it on the right af point?

Spot follows your chosen AF point. Centre weighted does not. That's what the camera does.

What you SHOULD do in terms of metering is fully dependent on what you want as the outcome of your image.

thanks so much for the info!

anyway, is it advisable to use the side AF point when shooting vertical shots? or the center AF point is the way to go? because i noticed that using the center AF point, you tend to move the camera more when recomposing.

Really....

So if I have my camera set to center-weighted than I am always taking a meter reading from the center focus setting, regardless of which focus point I am actually focusing on...

I never knew this.

I always thought centerweighted was just a "larger" spot metering setting.

You learn something everyday.

Personally I would advise using the closest AF point to the subject's face when shooting portraits at wide apertures (f/2.8 or larger) because there could be a difference in distance to subject when you recompose. This slight difference in distance could make the recomposed subject fall outside of acceptable focus.

However, the D70's non-central AF points are pretty shocking in low light or reduced contrast situations, due to its suckiness - technically known as not having cross hatched sensors.
