> Depth of Field
|
Bright exteriors mean small apertures
which means large depth of field.
If you set up this clothes line in
the darker interiors of your basement,
you would not be able to get all the
towels in focus at once.

The
second way to change depth of field is to adjust
your aperture.
2)
Aperture:
Aperture. Small aperture settings give you MORE depth
of field and large aperture settings give you LESS depth
of field.
So
shooting outside on a sunny day (which by definition
means a small aperture) means you have a LARGE depth
of field. Conversely, shooting indoors (where it is
much darker) means you have less depth of field.
What
if you wanted more depth of field indoors? You could
bring a light. Adding light would mean a the aperture
could be closed a bit, resulting in more depth of field.
So,
you have probably figured out by now that shooting telephoto
in a dark room is a depth of field double wammy. You'll
have a tiny depth of field in that situation. Great
if you just want just the subject's nose in focus.
