It's been a long time since I've used a hand-held meter. To check calibration, I point it at 18% gray card held at an angle half way between the sun and the meter, on a clear late summer day with bright sun, between 10 AM and 3 PM. The meter should read EV=14? Then, to make exposure of average subject, exposure should be increased by 1/2 stop (if meter reads f:8, then exposure should be made at f:6.3)? Is this correct? Thanks.
