Blair Camera Co., (Boston, MA)
- c. 1888
the Walker-Eastman Rollerblind Shutter was manufactured starting in 1886 doesn't
mean that Thomas Blair wouldn't invent his own version. There do not seem
to be many of these still extant; its period of manufacture or popularity must
have been limited.
The film was loaded in the darkroom, as were all focal-plane
shutters of this era. From the direction of the above photograph, the
ground glass tilts down to thread the film behind. The full and empty
rollers installed in the compartments on either end. For attachment to the
camera, it mimics the removable camera back, in that it
has a projecting thin ridge
all around that fits correspondingly into the camera's two vertical plates at the
bottom and large single clip on the top. It weighs a
ton; the stress in the thin ridge at the clip was tremendous. The size of the ground glass
of this example is 6½x8½".
The photographer that owned it also owned the pile of
plateholders shown - he probably used them when the rollerblind shutter stopped
working. Like most rollerblind shutters, the blind hangs up, inviting you
to break it.
