The
term "view camera" has been used to describe any of several
camera types--often monorail designs--and is currently used as the
title of the leading large format journal--View Camera--but
it is too inclusive to be of much help in choosing a camera type.
From a marketing perspective, standards movements are the defining
capabilities pitched for "view" and "technical"
cameras and these often are the features that photographers
seek in these camera types.
Historically traditional
"press" cameras and even some rollfilm and folders have
provided some movements. On first glance a technical camera may seem
little more impressive than a press camera. Their general design is
similar--a squarish case with a hinged front bed connected with pleated
bellows. They became different from press cameras incrementally. Linhof
began making metal cameras in the last decade of the19th cy, but the
Technika of 1936, which introduced compact rear movements created
the defining class, "technical camera." Though these looked
much like the contemporary Speed Graphics, the Technikas were more
precisely built and provided more of the features that were typically
found on monorail and flatbed cameras.
Standards movements are
significant to image composition because they allow using a greater
part of lens coverage to adjust perspective and provide a greater
ability to be selective in choosing the plane of focus .
These adjustments had been used for decades by professional photographers,
but as more compact "hand" cameras were developed, the mechanisms
to support movements were often jettisoned to save weight, cost and
complexity with a public that was often most interested in the easiest
way to preserve a moment.
A design
shared by press and technical cameras is that they both have self-enclosing
cases. A common understanding
of the difference between a press camera and a technical camera is
that the latter has a "technical" back--one that allows
rear movements for at least swing and tilt. The self-enclosing case
makes these designs quick to set up--attach the camera to the tripod,
drop the front, draw the front lens standard out on the bed to preset
stops, open the shutter and view the image on groundglass. Adding
to this convenience, many short and medium length lenses can be stored
on the camera and are protected when the bed is closed.
Both press and technical
designs can cause problems with short focus lenses, since focusing
is done from back to front. Short focus lenses require little extension
and the wider the angle of view, the more likely that the bed will
fall within that field of view. Virtually all press and technical
cameras have a drop bed mechanism that angles the front of the bed
downward. This requires using some front rise and front backward tilt
to return it to level. In cases where you might want to use front
rise to control perspective distortion or front tilt to control focus,
you may find you have little left in the ranges of those movements.
In press designs, the
back of the case has a film gate and groundglass viewing panel that
are in a fixed position. They do not support movements, or at most
back tilt, and cannot be rotated or reversed to switch between portrait
and landscape orientations. In early designs, the viewing panel was
not even removeable, but was only sprung to allow a film or plate
holder to be slipped in, hence the name, "spring" backs.
This kind of back continues in some woodfield designs. The Technika-type
back was a major innovation--it rotated and could be extended out
from the back of the case, allowing it to move independently, providing
limited swing and tilt relative to the rear plane of the case. Some
of the Japanese technical designs use a different type of back structure
that provides rear swing by allowing the entire case to pivot. The
Wista SP, of the latter type shown to the left, is adjusted for both
front and rear swing, while the Meridian above it is shown with its
Technika-style back extended.
While technical cameras
have at least rear swing and direct tilt, they rarely if ever have
direct rear rise and fall. Direct movements are those in
which the front lens mounting or rear film gate/viewing screen structure
move independently from the plane used for focusing--for example,
the rail used in most monorail designs. In press and technical cameras,
the focusing rail is attached to the inside bottom surface of the
case and is extended out onto the dropdown bed. While this is a more
convenient design, it is generally more limiting in providing movements,
particularly rear movements.
Most press and technical
designs provide direct rear backward tilt by changing the angle of
the case to the horizon--in practice, by tilting the tripod head backward.
This effectively tilts the case, and therefore the rear standard.
The Busch Model D--a press camera--is shown with the bed dropped and
the case tilted back. The front standard is no longer parallel to
the vertical axis. It can be returned to this axis by using front
forward tilt. These indirect ways of getting rear tilt and compensating
front movements can quickly limit other front movements that might
be desirable.
The drop bed method of
effecting rear tilt is also dependent on the design of the drop bed
mechanism. Some designs rely on spring loaded braces that have the
normal 90° bed/case position and a second position that is about
110-120°. Other designs have locking knobs that allow any degree
of forward tilt, a detent for the 90° setting and selected rear
backward tilt positions.
In addition to rear
movements, technical cameras are more likely have more types of front
movements and those they have are likely to have greater ranges.
A general caveat in choosing
a press or technical camera is that they have been manufactured in
several countries, by many companies and for eight decades or more.
As press cameras evolved, the movements on front standards equalled
and sometimes even surpassed movements on the earlier technical cameras.
Both Linhof and Horseman, noted for their technicals, have provided
models that had no back movements, sometimes marking them as "press"
cameras and sometimes blurring the distinction. Regardless of the
names that manufacturers use, features can vary considerably, and
of the four types of large format cameras, press and technical cameras
have the most in common. In shopping for a press or techincal
camera, you will avoid confusion and disappointment by clearly understanding
the features of different makes and models and your needs for features.
Most technical cameras
have alloy cases. Virtually all have interchangeable lenses. While
technical cameras can have integrated rangefinders and viewfinders,
many don't and depend entirely on groundglass composition and focusing,
sometimes without even focusing scales on their beds. While there
is no reason that a technical camera couldn't have a focal plane shutter
like Speed Graphics, I am not aware of any that do. Most have no linkage
connecting the between-the-lens shutter and the camera, though some
have accessory anatomical grips with cable releases that attach to
the shutter. Technical cameras generally have proprietary lensboards,
though many manufacturers follow the Technika/Wista model. Most technical
cameras have rotating backs, though some may have reversible backs
that must be removed to be reoriented. While early technical cameras
may have focusing panels that are not meant to be removed in service,
most later technicals have international (Graflok-style) backs with
removeable forcusing panels so that various types of film backs can
be attached with sliding clamps. Some designs have narrow gapes--the
opening for sliding in the film holder--while others have gapes that
allow the insertion of even rollholders.
Unlike
4 x 5 press cameras which were phased out in the 1960s, technical
designs have been produced continuously from the introduction of the
first Linhof Technika in the late 1930s. Modern technical cameras
benefit from newer materials, and while basic functions are similar
to earlier designs, new strategies for effecting them have often become
more sophisticated. WWII's impact on German and Japanese camera design
and manufacturering limited the development of technical cameras,
such that Japanese accendency in this market was delayed until the
1980s, when Horseman, Wista and Toyo found a significant market for
LF designs based on the earlier Technikas.
Technika and
Early Clones. The earliest Technikas had backs that could
be extended backwards on four posts mounted in the camera body, providing
direct rear tilt and rear swing, in addition to providing some additional
extension for longer lenses. Technikas are still made to exacting
Linhof standards. Some current models follow the traditional design,
with additional features. Earlier post-WWII models had some limitations
in front standard movements, but current models have generous front
movements in all planes and rear shift and tilt. Linhof also made
a Standard Press model without rear movements and front swing. Recent
Technikas in good condition are well beyond the price ranges established
in this site; those that are within that range are likely to be older
with fewer features and may have been heavily used.
Technika Review and manual
Beyond the Technikas,
there were two early competitors--Micro Precision (MPP) and Meridian.
They had all-alloy cases and backs that extended like the Technikas.
Both had rotating backs, but, as produced, neither were international
G designs. Meridians were made in two models. One of my Meridians
has been converted to a Graflok (international) G. Both Meridian models
have front standards that can be focused while still in the case;
the B model has a pinion-geared supplementary focusing rack in the
case.

Later Japanese makes
have a greater range of front and rear movments and often very interesting
collections of accessories that can expand flexibility and streamline
workflow.
Wista.
The earliest Wista, branded as Rittreck View, was a 5 x 7 with a 4
x 5 reducing back. Some other early models featured the Wista rear
swing movement that pivots the rear standard using a plate system.
All of the current Wista technicals have this feature; the SP has
an additional mechanism that controls swing more precisely. Both the
Wistas and the Toyos (below) have hinge systems that allow variable
rear tilt angles forward and backward. Some may prefer this tilt/swing
arrangement to the Technika-type design, or not. Because of this plate
pivot system, it is not possible as it is with cameras with the Technika-style
back, to get additional extention by using both swing and tilt movements
simultaneously. Wista technicals with rear shift would be rare if
they exist. Both the current Wistas and the Toyo A-series have short
beds that improve wide coverage before having to drop the bed to keep
it out of the picture. Both have double extension racks. The Wistas
will focus a 65mm lens without special accessories. Wista makes many
accessories, including a foldable 4 x 5 reflex viewer; a 6 x 9 sliding
back that mounts a switchable groundglass panel and a rollholder.
There is also a unique recessed lens frame and bag bellows that may
have the distinction of the 4 x 5 technical that can focus the shortest
lenses. The recessed lens board is actually an open frame that provides
excellent access to shutter controls. Currently available models include
the VX and SP without integrated finders and the RF that has them.

Horseman.
A defining characteristic of Horseman technicals is that the designers
balanced lightness against features--a signal combat in the design
of portability and capability. Like Linhof, Horseman invested in design
of both medium and large formats. There are VH and VHR models that
provide nearly complete front and back movements for the 6 x 9 format
and there are HD and FA 4 x 5 models that straddle the divide between
minimum weight and maximum function.
The VH and VH-R are clones
of the Linhof 6 x 9 Technikas. They have front shift, swing and tilt
and a Technika-style rotating back for rear swing and tilt. The difference
between the two models is that the R version has a bright, but uncoupled
rangefinder/viewfinder system. This full-featured design comes at
the cost of weight; the VH weighs in at the weight of the more limited
HD, a 4 x 5 model built to provide more limited functions, but larger
images. HD's have about the same featureset as Super Graphics, yet
they are considerably lighter, largely because the HD backs are not
rotating, but reversible. Neither has other rear movements other than
backward tilt via the drop bed. HD front movements include shift,
tilt and swing. The Horseman 4 x 5 FA model has all front movements
and includes a Technika-style back that is reversible. With Horseman,
you can get what you are willing to tote and pay for. All of the Horseman
technicals use an 80mm square lensboard; this can cause problems mounting
some short focus and/or large aperture lenses with large rear elements.
Some Horseman technicals may still be available in Japan and perhaps
other markets, as new old stock; most models are frequently available
on the used market. I've found little consolidated Web-based information
about Horseman technicals so I've started my own pages.

Notes on 2 x 3 vs. 4 x 5
Toyo.
Toyo and Wista technicals are the only full-spectrum brands that are
currently available as new in the U. S. Like Horseman, Toyo is keenly
aware of the cost/weight calculus. Toyo offers both a lightweight
field camera and two technical cameras. Toyo has pioneered the use
of carbon fiber in LF camera bodies. Their CF model is a field camera
made of carbon fiber and stategically placed metal parts, it is about
the same weight as a woodfield camera. Toyo lists 90mm as the shortest
length it focuses and it has a fixed bellows. It has generous front
standard movements, rear tilt and a reversible back
The A-series are technical
cameras. Like the Wista, the A-series has a bed hinged for variable
rear forward and back tilt.The AX has an all-alloy case with rise/fall,
shift, swing and tilt on the front standard, plus rear swing on a
reversible back. The AII
is essentially the same camera with a rotating back. The Toyo A-series
will focus 70mm lenses on flat boards or 47mm on recessed boards.
Toyo uses 110mm square lensboards which may mount some large diameter
lenses that cannot be mounted on smaller boards, like the Technika/Wista
and Horseman. Unlike the Wistas, the Toyo have fixed bellows. Toyo
offers a 6 x 9 sliding back adapter that can mount digital and film
backs. All current Toyo models have an 4 x 5 international G back.
