Depth-of-Field Scale
The depth · of·field scale indicates the range of subjects
which will be in focus sharply on the film . In this case, the
depth·of · field behind of the subject is deeper than in front
of subject. This range will vary with the following factors:
The depth·of · field will be deeper the smaller the aperture
opening, the further the distance of the subject, and/ or the
shorter the lens focal length. The depth · of·field will be
shallower
the larger the aperture opening, the nearer the
distance of the subject, and/ or the longer the lens focal
length.
For example, if the lens used is 50mm and the subject has
been
focused at a distance of 3m (10 '), with an f/8 aperture
opening read off from both indexes on either side of the indio
cator (orange line), the depth·of · field is from approximately
2.3m (8') to 4.3m (14').
If the aperture is closed down to f/ 16, the picture will be·
come sharp between
1.9m (6') to 7.6m (25') from the
camera. This range will vary with the f/stop selected.
