6. About Exposure
Setting the Exposure
When taking photographs using TIL metering,
no exposure compensation is necessary to meter
the light coming through the lens.
With
TIL metering, AE (autoexposure) is
possible at all focusing distances. Just set the
desired picture-taking mode, then check the
shutter speed and aperture before taking the
picture.
Magnification and Effective f-
number
The aperture displayed by the camera assumes
that the focus
is set to infinity. The actual
aperture (effective f-number) becomes darker
(~ffective f-number increases) at closer focusing
distances (magnification increases). This does
not cause exposure problems for normal picture-
taking. However, for closeup photography, you
cannot ignore the change
in the effective f-
number.
When you use a handheld exposure meter to set
the exposure, you must take into account the
exposure factor shown
in the following table.

[]] • The correct exposure for a close-up shot largely
depends on the subject. Therefore, try
to bracket
the exposure for the same subject.
• Using aperture-priority
AE (Av) or Manual (M)
picture-taking modes are recommended for
macro photography as it
is easy to adjust depth
of field and exposure
in these modes.
o If your eye will not be covering the eyepiece when
the picture
is taken (with remote control operation,
etc.), use the eyepiece shutter or eyepiece cover.
This prevents stray light from entering the
eyepiece and throwing off the proper exposure.
