The Ross Keros camera was first advertised from 1913 and was made for Ross by Kershaw of Leeds. The camera included a Kershaw revolving back which was seen as a useful feature for the hand camera where rotating the camera itself 90 degrees was impractical. The camera was a standard hand and stand type 'strongly made in mahogany, covered Morocco leather. The inside is black polished and the metal fittings are finished in permanent dull black'. Ross highlighted the revolving back and wide-angle movement as separating their camera from the numerous others of this type on the market. The Multi Speed shutter was invented by G. Ditez in the United States in 1906 and sold in England by Ross.
