The Ruby is a wooden folding field camera made by Thornton-Pickard from about 1890 to 1907.[1] Intended for use on a tripod, the folding bed includes a turntable. The design was changed to make the camera also usable as a hand camera.[2]

McKeown states that the camera has a 'Ruby' Rapid-Rectilinear lens.[3] This is mounted on a Thornton-Pickard roller-blind shutter on the front standard.

The Royal Ruby is a very similar camera, introduced as a high-specification version of the Ruby in about 1900,[4] and continued in production for some years after the standard Ruby was discontinued. McKeown states that all Royal Ruby cameras are triple extension (allowing close focus, or long-focus lenses).[3] Examples exist with roller-blind shutters on the lens board,[5] and with a built-in focal-plane shutter.[6] There is also a half-plate stereo model.

The Special Ruby, strangely, was introduced as a lower-specification version of the Ruby, also shortly before the standard model was discontinued.[3] Wood and Brass shows an example from 1909-12, with a spring back (for easy insertion of dark slides in front of the focusing screen) and with triple extension;[7] the notes state that these features were among those left off the Special at first, and that they were reintroduced in about 1908, so the camera is very similar to a standard Ruby. McKeown lists the special Ruby as double extension.[3]
