currently using a D70, inside the viewfinder, there is something like this, excuse my illustration
i usually focus my subject within the semicircle and 3 "horizontal" rectangles... What's the 2 "vertical" rectangles for?
also, for images such as below
i.e. sky bright and subject turns out dark, did some reading, does centre weighted metering solve the problem? would centre weighted metering also solve the problem where you want to take a photo of a person who is in a tall building maybe like taipei 101 (indoor and fairly dark) but also want to capture the outdoor scenery (bright, sunny)? hope i make sense!
