EV RANGE OF THE CAMERA—continued
How to read the EV chart
Full-aperture metering
Example: Lens maximum aperture: f/1.4
ASA film speed: 100
Working aperture: f/5.6
By referring to the f/1.4 column in Section A and the
EV values Indicated for ASA 100 In Section D, you will
find that the EV range for an f/1.4 lens at ASA 100 is
1 to 18. Now, refer to Section В and single out the
f/5.6 Indication for ASA 100. Go diagonally down
until the protruding line intersects with Section C’s
vertical line for the shutter speed of 8 sec. (the EE’s
slowest shutter speed). From this point of intersection,
follow the horizontal line that leads to Section D*s
EV value for ASA 100, and you will obtain an EV
value of 2. Start again from the f/5.6 indication for
ASA 100 in Section B, and go down diagonally until
the protruding line intersects with Section C’s verti­
cal line for the shutter speed of 1/1000 sec. (the EE’s
fastest shutter speed) this time. Then follow the hori­
zontal line that leads to Section D’s EV value for ASA
100, and you will get a reading of EV 15. This means
that an f-stop of f/5.6 at ASA 100 and a shutter speed
of from 8 to 1/1000 sec. has an effective EV range of 2
to 15, which is well within the EE’s metering range of
EV 1 to EV 18. The area encompassed by the heavy
lines in Section C demonstrates a metering range for full
aperture method using an f/1.4 lens and ASA 100 film.

Stop-down metering
Example: ASA film speed: 100
Stopped-down aperture: f/8
The procedure is the same. The f/8 column in Section A
and the EV values indicated for ASA 100 in Section D
will show you that the EV range for f/8 is 6 to 23. Refer
now to Section В and single out f/8 at ASA 100. Go
diagonally down until the protruding line intersects with
Section C’s vertical line for the shutter speed of 8 sec.
From this point of intersection, follow the horizontal
ine that leads to Section D’s EV value for ASA 100, and
you will obtain an EV reading of 3. This means that an
f/stop of f/8 at ASA 100 and a shutter speed of 8 sec.
give an EV value outside the metering range. To find
out the slowest shutter speed usable, follow the f/8 indi­
cation for ASA 100 in Section В diagonally down until
it intersects the horizontal line in Section C that leads
to Section D's EV value of 6 for ASA 100, and you will
find that the slowest shutter speed usable is 1 sec. In
other words, at f/8 and ASA 100, the available shutter
speed range that is within the metering range is from 1
to 1/1000 sec., which has an effective EV range of 6 to
16 (indicated by the broken line In Section C)—well
within the metering range.
In practice, you will find that it is generally the high
end and the low end which require a careful check.
The EV range of the Nikon EE encompasses most
ighting situations, and it is only under dim-light or
extra-bright picture-taking situations that you need pay
any special attention.
