1 This bath fixes the print, arf. at the same time toughens the film
t tto such a degree that it can be washed in warm water, and if neces-
sssary dried by heat.
The following points should receive attention
:
The same dish should not be used for developing and fixing.
On no account should hypo be allowed to contaminate
the developer.
If the hypo solution is splashed on to the Bromide paper,
or transferred from the clothes of the worker, at any
stage before fixation, stains will result.
The print must not be exposed to any light except that of
the dark-room until fixation is complete.
To ensure complete fixation, the prints should be im-
mersed face downwards
; they should on no account
be allowed to float on the hypo bath, otherwise dis-
coloration is liable to occur.
A fixed print which is allowed to float film upwards on
the hypo bath for a considerable period will begin to
bleach, and in time the image will almost entirely
disappear.
After the prints are fixed they must be washed.
Many people
ppsay little attention to the sufficient fixing of the prints, and devote
ai great deal of time to washing them.
The reverse is better,
akllthough neither process should be neglected.
Prolonged washing
iss; a mistake
; what is required is to eliminate the hypo as quickly
a^iss possible.
For this there is nothing like running water, and many
washers are made in which prints can be washed without requiring
mniuch attention. If the washing is to be done in a dish, then what
h;i;as been said about fixing applies with equal force to washing.
Trihe prints must not be allowed to overlap unless they are kept
inni continual motion. Consequently for small prints,
if there are
mniany of them, a big basin will be found more suitable than the
flslaat photographic dish.
