OVER-DEVELOPMENT.
Caused by leaving the negative too
long
in
the
developer.
In
this
case,
the
negati
ve
is
very
strong
and
intense
by
transmitted
light
and
requires
a
very
long
time
to
print
.
The
remedy
is
obvious.
UNDER-DEVELOPMENT.
Caused
by removal from the
developer
too soon.
An
undeveloped
negative
differs
from
an
under-exposed
one,
in
that
it
is
apt
to
be
thin
and
full
of
detail,
instead
of
harsh,
and
lacking
in
detail.
If
the
development
is
carried
on
as
before
directed,
this
defect
is
not
liable
to
occur.

bells
on
the film
III
the developer

cause spots;
and
streaks

the
film to remain
uncovered
in
part

the various solutions while in them,
White, milky spots
are
evidence
that

negative
has
not
been
properly
fixed,
and

negative
should
