I got me a Sekonic L-308 DC to get started with lightmeters. The manual says it's calibrated coming out of the box.
But for both my cameras (Sony FS100 and Canon 7D) I had to push the calibration by +0.6 EV in order to get proper exposure.
Is there a way to check, if this thing is really calibrated when set to 0,0 EV correction? Maybe by measuring a standardized light source?
I thought about incident metering the sunlight (with the LumiDisc on, instead of Lumisphere) and compare the lux/fc value to the ones in the books. But since there are reflections of buildings and whatsoever, clouds, different angles ... wouldn't a tungsten source be better?
Also I can't really get use of the spot meter. Since it has an angle of 40°. If I get to close on a surface, to tighten the viewing angle, the meter of course casts a shadow on it.
Any ideas on how to use it properly?
