I have had many opportunities to observe pro photographers shooting indoor/event. Realise that they always half-hold button, point to another object, before pointing back at the subject and shooting. I believe it's to tell the camera how much black or white there is to make the photo brighter, right? Could someone/s explain how this technique works?
Thanks a lot!

It can also be the method of "focus lock & recompose" - which has nothing to do with metering. Unless you know the settings of the camera it can be either one of the 2 methods: "Exposure Lock & Recompose" or "Focus Lock & recompose" - or even both.
Focus lock is used when the main object is not placed under one of the focus points of the camera (be it intentionally or not). Then it's good to use a single focus point (check camera manual how to use it), focus on the main subject, lock the focus, recompose the picture and press the shutter fully.

thanks for the reponses. could you explain more on the recomposition part?

It's quite simple. Most likely, they are using the center focus point, so they are focusing on whichever subject they want in focus.
Now, if they want the subject in the center, then all well and good, they just fire off after shooting, but sometimes, you want an offset subject (such as when following the rule of thirds), so after focusing using the center AF point, they then recompose to shoot the scene with the subject at whichever placement they wish, while holding the shutter release at half-press to maintain that focus lock.
I do believe, in most cases, it has nothing to do with metering.

Depending on how a camera is configured or customised to work. It could be focus lock recompose, or FLR and Auto Exposure Lock AEL, or FLR alone, or FLR AND AEL but so far, I don't see many togs using AEL that way.
Also, on the area of focus lock, apparently and according to Canon's literature, FLR is not always accurate, especially for distances under 15 feet.

half press to focus on subject
while still half press
recompose your shot
full press to shoot

This is explained in almost all camera manuals in the "focus" section, as well as discussed extensively here and online. Please try a search for "recompose picture" or "focus recompose"
