e. The film should be flat and taut with the punched number (if any) at the bottom of the hanger. If it is
not, repeat the procedure.
Suggested arrangement of manual processing tanks is shown in Figure 6-38. The chemicals should be arranged as
shown in the sketch in sequential steps of the process and traversing from left to right. This arrangement is used with
the assumption that most people are right-handed.
Figure 6-38. Suggested Arrangement of Manual Film Processing Tank.
a. Be sure all films are placed on hangers properly.
b. Check the temperature of all processing solutions using a bimetallic thermometer. Refer to Table 6-16.
c. Agitate the developing chemicals and make sure they are at the proper level; replenish if necessary.
d. Be sure wash water flow is adequate. Refer to Table 6-17.
Developing Procedure. (See Figure 6-39)
Do not allow films to remain out of solutions for extended periods of time since this
will cause uneven development.
Drain the films and hangers for several seconds between operations to prevent
carryover of chemicals from one tank to another.
