Description
The Bilora Stop Box camera was manufactured by the Kurbi & Niggeloh Company of Radevormwald/RHLD, Germany from 1935. This 1935 pre-war version of the camera is capable of capturing 6 X 9 cm exposures on 120 roll film. It is made of metal with imitation leather coverings.
The fixed focus lens with two aperture settings. It features a simple time and instantaneous shutter. A double exposure prevention mechanism is present. You must wind on before you can take another shot. An indicator on the side shows whether you can take another shot or have to wind on.
There are two brilliant finders, one for portrait and one for landscape. A cable release socket can be found under the shutter release lever. Film advance is by red window which has a sliding metal cover. It has two tripod sockets. The camera is opened by pressing on two small chrome buttons on either side.
How to Use
This camera takes 120 film which is easily available from photographic outlets.
As the shutter speed is only 1/50s, it is advisable to use a tripod to get clear shake free images. However, holding it against a wall or other solid object would work as well. For quick snapshots, hold it firmly against your body.
If you don't want to bother with an exposure meter, follow the guide shown. It is based on the 'Sunny 16' rule. Film is so forgiving and will produce acceptable results even when overexposed by 2 or 3 stops or underexposed by 1 stop.
The tables assume that the sun is at least 30 degrees above the horizon - that's 10am - 5pm on a summers day (May - August) in the UK.
Remember that the exposure guide in the manual may not be helpful as it is based on the use of old film with a low ISO value.
