this is a bit embarrassing but i've never been much cop when it comes to metering a scene. I'm fine when it comes to portraits because I know where i'm pointing my meter but when it comes to landscapes i always feel like i'm doing it wrong. I generally tend to point the meter in the direction the camera's pointing but something someone said recently made me think i should do more.

Should i take more than one reading? Should i take the meter as fact even if i'm reading a scene which is mostly in shadow? I use a Weston III meter and would really appreciate someone explaining it to me as if i was a 2 year old
