    Using a Nikon N90s. Normally use spot meter for exposures. Want to
    supplement the camera light meter with a handheld one for reflective and
    incident light. Also want to use the handheld for a viewfinder camera w/o
    TTL meter. Tried to check the handheld meter against that in the camera.
    At distances >= 50 ft, the meters agree within .4 EV(stops). For close-ups,
    using a gray card, the meters can be over 2 stops different. And, yes, I
    am correcting for the Exposure Increase Factor due to magnification. The
    camera is providing well exposed pictures. Checked the light meter against
    another new one at the camera store. What am I doing wrong?
