is always brought along, but it might just as well be placed on a tabletop. It has equally sized rectangular front and back panels on a full-width double-extension baseboard that is hinged near the front. The front panel, holding the lens plate, has horizontal and vertical movements, while the back is tilt-suspended on brass standards running on brass tracks on either side of the baseboard, providing

regardless of lens offset position. The camera folds flat, after the back panel is brought forward to the lens panel, by folding the hinged base board up, and thus conveniently protecting the focusing screen. For insertion of the wooden dark slide plate cassette, the hinged focusing screen is swung up and away. The Reisekamera was made available for several plate sizes; most common are the 13×18 cm, 18×24 cm and 24×30 cm versions. Shutter and

The Reisekamera might be considered the portable version of the studio camera, to be used outside the professional photographic studio, on assignment at location, for architectural work or documentation away from the studio, in homes or museums.

ed, the focusing screen is replaced by the plate holder. The lens cap is placed on the lens, the dark slide removed from the plate holder, and the lens cap is removed for the required exposure time and replaced. If an auxiliary shutter is present, it may perform the function of the lens cap. After the exposure the dark slide is replaced to protect the exposed plate from stray light. The plate holder is either turned for a second photo, or brought to the darkroom for plate development and copying. The camera would be supplied with a number of plate holders, each usually holding two plates, one on either side. The Reisekamera was a popular wooden bellows

The Reisekamera is, regardless of the maker, quite similarly built and of almost standardised design, often without maker's identification. The collector's usual practice to identify some of these cameras by its name plate, if present, or even by the lens attached, results in almost identical cameras being attributed to more than one brand name. The original designer or manufacturer has not been ascertained, but it is thought to originate in the

region of Germany around 1860, and in fact, many Reisekameras came from Dresden or Görlitz in particular. This region had a highly specialised woodwork industry well suited for camera manufacture. As the type became popular, manufacture of similar cameras took place worldwide, but these are more often than not clearly marked with the manufacturer's name. Possibly the best known Reisekamera is the Globus, manufactured by Ernst Herbst & Firl, Görlitz for the camera manufacturer Heinrich Ernemann in Dresden.
