Pentax K1000 - Infra-red Photography

HELPFUL HINTS ON EXPOSURE PROBLEMS
The light meter built into your K 1 000 correctly
reads the average of the I ight reflected from
the entire scene as seen through the viewfi nder
-
with a little extra importance, or weight,
given to what is in the center. Sometimes,
however, there is a great difference between the
light reflected from the background and
the I ight reflected from the subject. In such
a
case, to achieve a really good photo, you
must compensate for the difference by opening or
closing down the aperture 1 or 2 steps.
As a
general rule, when the subject is darker
than the background, you compensate by
opening your aperture 1 or 2 steps further.
For example: on a bright day, when your
subject has his back to the sun and you are
shooting
directly toward the sun ... or when
you are shooting a subject against snow or
I ight-colored sand ... or when you are
copying a page of black letters on white
paper, increase the size of the aperture
somewhat.
When
your subject is brighter than the back-
ground - if he is standing in a spotlight, for
example - you make the aperture 1 or 2
steps
smaller to compensate.
