A self-timer is built into the front of
the Leica M 3 and may be adjusted for
any delay between 5 and l0 seconds. It is
set by turning the lever to any inter-
mediate position between horizontal and
vertical and is operated by pressing a small
button immediately above it.
Cold weather enthusiasts will find the
Leica M 3 ideal. All controls can be set
and the camera smoothly operated while
wearing heavy gloves or mittens. The click-

together with the lever-operated film ad-

power or ability to record fine detail. As-
suming the size of the sensitized silver
grains to be equal in different films of the
same speed, the film's ability to record
fine detail is directly related to the thick-
ness of its emulsion layer. The thinner the
coating of emulsion that can be put on the
base, the higher the resolution of the film;
the thicker tha't coating, the less the resolu-
tion.
A given point in the object being photo-
graphed will be recorded on the film as an
area larger than that imaged by the lens.
The detail that can be reproduced on film
is limi,ted to the base length of the triangle
formed by light penetrating the emulsion.
There will also be some scattering of light
within the emulsion which will further
enlarge the image. If the thickness of the
