Kenko’s KFM-2100 Flash/Ambi Meter; Everything You Always Wanted In A Handheld Meter, And More Page 2

In Action
Using any incident meter simply means holding the meter at the subject position, with the dome facing the camera. That gives you an exposure reading unbiased by brightness levels or tonality. Indoors, the meter must be held practically up against the subject, since the Inverse Square Law tells us that light levels decrease dramatically with distance--and we'd like to get as accurate a reading as possible.

While the main display is not backlit, there is enough contrast to make readings usable under most light levels. I never had a problem with it. The spot read-out, however, is illuminated.

Placing this ceramic figure against a milk-white Plexiglas-like surface produced modest underexposure when metered with the camera (top, left underexposed). An incident reading yielded better tonalities (2nd). Then I decided to bounce a shoe-mount flash off the ceiling for overall fill, using the meter's Light Ratio Analyze function, increasingly boosting power on the flash till the right amount of fill was achieved (3rd & 4th).

One more important point: while you can take readings as EVs (via a custom setting, for ambient light only), measurements are largely shutter-priority. That's designed to keep you on track when using flash, for proper flash sync. Granted, I would have liked to make readings in aperture-priority, but I found this workable. And when you stop and think about it, this design also simplifies meter operation.

Incident Meter Test
As long as your subject is not in shade and you in shadow (or vice versa), a few feet apart will not affect an incident reading. When I suddenly found this beautiful white dog at Nova Scotia's Brier Island Lodge posing for me (okay, the dog was totally oblivious to my presence) and not wanting to disturb it, I stood several feet away and made an incident reading. Oh, and did I mention we were enshrouded in fog? The camera meter grossly underexposed the scene because of both the dog's light tonality and the prevailing wash of light tonalities surrounding us. The Kenko meter produced a beautiful image.

The predominant light tonalities fooled the camera meter into serious underexposure, by 1.3 stops (left). An incident meter reading with the Kenko meter produced beautiful tonalities in the dog's coat and surrounding fog (right).

I've used lots of meters over the years. I was impressed by this meter before, and continue to be impressed now. Kenko did a good job preserving the integrity of a meter that has long been a cornerstone for serious and professional photographers.
