Hey guys,
I just started using AE Lock in Av mode recently and I need to know where do you meter it at? for example for portraits, do you meter it at people's eye/skin/etc? for birds with colorful feathers, do you meter it at the brightest/darkest feather? is there any generalization on where one should properly meter before pressing the AE Lock? I've tried googling and reading the manual about this but couldn't find any information about it (or maybe I missed it).

and when using AE Lock, is it more advisable to use Spot Metering instead of Partial Metering?

here's a sample of a picture I shot in Av mode and used AE Lock with Spot Metering. I focused on the duck, then locked the exposure at the brightest feather of the duck and recomposed. Did I do it right? or was method wrong?

My camera is set to shutter half press = AE lock, * button = AF, shutter full press = click off a shot, but it's essentially the same thing.

In a backlit situation like this I always spot meter my subject and if I need to keep shooting that subject, I switch to M mode and dial in the spot metered settings.

One important thing to understand is that AE lock and metering are related, but the exposure method (Av in this case) is not.

Metering can be done with evaluative, partial, spot and center weighted average with most cameras. In all cases can the metered value be locked.
If you use evaluative and One Shot AF, locking is always implied as soon as metering starts. In M mode, there is no locking, since M mode by itself is locked to whatever you set (unless combined with Auto ISO on later cameras, but that's something else).

My advice is simply that you meter what's important to you. If that part is very bright, or very dark, you will then either have to meter something like a gray card, or something more neutral that's still lit about in the same way as your main subject, or compensate +/- the metered value. Something which can be done with exposure compensation or by switching to M mode and lock the compensation there, as suggested in a reply above.
