Among hand cameras of the ordinary type, in which the shutter employed is not a focal plane blind, none are better known than the Kodak cameras.
These are sold in different sizes and at very varying prices, and some of them are sufficiently small to be easily carried in the coat pocket, their shape being suitable for this, as can be seen from the accompanying pictures of two extended for use. (Figs. 58 and 59.)
These cameras (at least the more expensive ones) can be used with plates or roll films.
Reflex Cameras. — Another hand camera which may be noted is the Reflex. In the older forms these cameras were of the box type, and so suffered under the great disadvantage of being decidedly cumbersome. This objection has been removed quite recently by the production of Houghton's Folding Reflex, a camera which when closed is no more bulky than many folding hand cameras of the ordinary type. The next two pictures illustrate this camera, the first with the hood raised and opened ready for use, and the second closed for carrying. The release of the shutter is arranged on the right-hand side, so that by gently pressing with the thumb the shutter is released and the mirror left in position for the next exposure. When opened the side struts lock, and the camera becomes perfectly rigid.
