There is no reason to think that a hand held meter is more accurate than the one built into the camera. It is all a mater of how meters, and instruments in general, are used. They measure exactly what they are designed to measure, and if they are working properly, will do it accurately. People get into trouble because they don't understand what is really being measured, and then blame the instrument for poor results. Using manual flash calculations with guide numbers, distances and f-stops is also fool proof. There is a reason why many wedding photographers still use manual flash particularly for candids. The world is not a photo studio and incident light/flash meters are not always practical.
BR From: "Feroze Kistan" <[EMAIL PROTECTED]> Would this technique, which sounds foolproof, apply to handheld meters in general then? I'm getting the impression that they are more accurate than using the cameras onboard meters is this correct?
