(fig. 10-3). They are constructed of perforated metal or
plastic and channeled to receive and suspend film in
solution. This allows the solution to circulate freely over
the film surface. Sheet film hangers are used in tank
developing and their use is described later in the this
chapter.

ROLL FILM TANKS AND REELS

Hand processing of roll film is usually done on reels

in roll film tanks. The center-feed reel and tanks used

most commonly in the Navy are made of stainless steel.

The film is wound onto a spiral reel. The reel is then
placed into a tank for processing (fig. 10-4).

TRAYS

Trays used for processing photographic film (roll or

sheet) are the same as those used for processing
photographic prints. They may be made of any material
that is not affected by, or cause contamination of,

photographic solutions. Most trays used today are made
of stainless steel or plastic.

SHEET FILM DEVELOPING TANKS

Tanks used for developing sheet film come in a

variety of shapes and sizes. They are usually made of
stainless steel.

To process sheet film in tanks, load the film into

sheet film hangers and then place it into the developing
tanks of solutions (fig. 10-5).

FILM WASHING EQUIPMENT

Film washing does not require special equipment.

Sheet film can be washed in the same type of tank or
tray that is used to process the film or in tanks designed
for film washing.

When a tray is used, only one film at a time should

be washed. When more than one piece of film is washed

at a time, the films will probably rub together and be
