The Kershaw Raven is a black Bakelite folding bed camera for type No. 120 rollfilm. It is a handsome and heavy camera. It was made in England by Kershaw Soho (Sales) Ltd. in about 1947. The Bakelite front door unfolds as the bed for the lens standard and is reinforced with a metal plate to mount the folding struts. When unfolded the lens standard position is fixed. The door carries a tripod bush and a folding table stand with a second tripod bush for landscape pictures mounted in the side of the body. The door carries a distinctive oblong shaped pattern and the rear of the camera features a star embossed into the Bakelite.
The Raven has a 4-inch (100mm) f/6.3 Kershaw Anastigmat triplet lens. A dial-set everset shutter gives speeds of 1/25, 1/50 and 1/100 second, plus 'T' and 'B'. It has a cable release socket. The aperture stops from f/6.3 to f/22. There are both a brilliant finder and a collapsible frame finder. Focussing is via a rotating front-element giving a range from 6ft to infinity. Frame advance is by red window which is square shaped and is not linked to the shutter.
How to Use
This camera takes 120 film which is easily available. It supports Timed mode and Instant with a speeds from 1/25 to 1/100 sec. It has a aperture settings from f/6.3 to f/22. With slow shutter speeds of only 1/25 or 1/50 sec, make sure you brace the camera against your body or use a tripod and press the shutter smoothly to avoid camera shake.
If you don't want to bother with an exposure meter, follow the guide shown. The shutter speeds are 1/25s, 1/50s and 1/100s. 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.
Remember that the exposure guide in the camera user manual may not be helpful as it is based on the use of old film with a low ISO value.
The tables assume that the sun is at least 30 degrees above the horizon - that's 10am - 5pm on a summer's day (May-August) in the UK.
If you are not sure about the light level, err on the side of overexposure - i.e. assume the smaller f number.
Where there is a choice, a larger f number will give a larger depth of field.
