Thanks lads, some very usefull info here.

The thread brought up one more question, when I set the meter in reflection mode and aim for the part of the subject I want to have the exposure based on it should be okay.
But with a 20degrees reflective meter one should get closer to the subject to take a good measurement. Will this give the same result as using a 5deg meter from the same distance as the camera is?

Something tells me this is different from the principle used with the flash lights getting closer or further away...

And sorry for being a bit too analitical about this, but I just want to think about this now so it will become a neutral habbit in the future with a much higher succes ratio.

cheers!
