Description
The Braun Imperial box cameras were made by Braun in Nuremberg, Germany. The 1950 Imperial 6x9 has a design like other box cameras of this format, with two built-in reflecting type finders, one for portrait and the other for landscape. It has a two position aperture labelled 'bright'(f/22) and 'dull'(f/16). The simple rotary shutter has both instant and time settings. Film advance is controlled by winder knob and red window. It has got two tripod mounts, one for portrait and the other for landscape. There is a connection for cable release.
How to Use
This camera takes 120 film which is easily available from photographic outlets. Basically it is a snapshot camera for a sunny day.
As the shutter speed is only 1/50s, hold the camera firmly against your body to reduce shake. However, holding it against a wall or other solid object would work as well.
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 table assumes that the sun is at least 30 degrees above the horizon - that's 10am - 5pm on a summers day 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.
