machine speed), the type of film, the agitation used,

contrast, the latitude, and the useful exposure range.
Figure 2-6 at the end of the chapter shows
a typical characteristic curve with the various parts
and their names. Refer to figure 2-6 frequently
exposure (log H) or horizontal axis. The length and
slope of the straight-line section are the main
variations to the shape of the curve. All densities on
the straight-line section of the D-log H curve increase
proportionally with an increase in development time.
The slope or gradient of the straight-line section of the
curve also increases, as development is increased; that
is, it gets steeper.
