Incident metering of light sources?
I'm looking for some enlightenments on how to use the incident metering mode of my Sekonic L308s to meter light sources.
If it's a person's face, I can simply hold the meter with its back to it then take a reading; If it's a lamp, I thought it'd be correct if I hold the meter with its face to it then take a reading. The result would be vastly different (overexposure) from using the reflected metering mode. I'm thinking that's because if the person's face is as close as it can be to the lamp, the face will be much dimmer the lamp, unless it's a mirror.
So is it still possible to use an incident meter to get a correct reading of a light source?
Any clue is appreciated!
