5. Take the picture! Everything between
the two distances (10' and infinity) shown
by the matching f/11 numbers on the
Depth-of-Field Scale (27) will appear
sharply.
It's a professional technique - but you don't
have to be a professional to use it for better
photographs.
The second way:
B. Using Viewfinder at Taking Aperture. Move
the Auto/Manual Switch (14) on lens to "
M" position. This closes down the lens to
whatever opening has been set on the
Aperture Ring (26). You'll be able to see
how distant and nearby objects "sharpen
up" at smaller lens apertures such as f/11
or f/16.
Naturally, when the lens is "stopped
down," less light enters the viewfinder,
and it is more difficult to see or focus
clearly. The principal benefit of this
technique is that it gives you a fast,
accurate "preview" of what will and
will not be sharp in the finished photo-
graph - for example, that telephone pole in
back of your subject. If it appears sharply
when the lens is "stopped down" to the
intended aperture, it will appear sharply in
the final photograph. By 'previewing'
your depth-of-field in this way, you'll
soon learn to select the aperture required
for the depth-of-field you want .
Either of these techniques will prove valu-
able in the great majority of picture taking
situations. For extremely critical applica-
tions, a printed depth-of-field chart is availa
ble on request.
