Pentax ME Super - Stopping the Action and Depth-of-Field Control

a wide lens aperture. As the camera automatically chooses the
fastest possible shutter speed for the given exposure, wide apertures
will
give

shutter

lighting

(NOTE:
This
technique
does
not
work
in
low-lighting
as
low
lighting
necessitates
a
slow
shutter
speed.)
Depth-of-Field Control: Depending upon the aperture in use, the
over-all
sharpness
of
the
picture
area
in
front
and
behind
the
subject
will
vary
greatly.
This
effect
is
known
as
“depth
of
field”
and

vary
the
over-all
effect
of
your
photos.
Maximum Depth of Field: The depth of field becomes progressively
deeper as the lens is stopped down to smaller lens apertures and is
greatest
at
minimum
aperture.
Thus,
if
you
desire
to
have
both
your
subject and the background in focus, use a small aperture such as
1/11 or 1/16 (be sure to take precautions against camera shake if
a yellow LED lights). Small apertures are also useful for critical
close-up work, but for this, refer to a close-up photography guide,
Out-of-Focus Highlights: The depth of field becomes progressively
shallower at wide lens apertures, and is shallowest at 1/2, f/1.7 or
1/1.4, depending upon which is the maximum aperture of your lens.
A shallow depth of field produces an out-of-focus effect which
highlights your subject. As long as the LED does not light at the
"OVER" setting, you can obtain this effect, even on a bright,
sunny day, by using а wide maximum aperture.
