The focussing cloth should be of ample size, at least a yard square, and may be even larger than this one way with advantage. It will be much easier to control in a wind if it comes well over the head and shoulders when focussing. Any opaque material of light weight will answer, and if made of a good waterproof cloth will serve the purpose of protecting the camera, and even the photographer as well, in the event of a sudden shower. Mine is black one side and is lined with a green material, which enables this side to be used for concealing the camera and tripod, to some extent, when necessary. It may be fastened to the camera, either by having a hole made in it to fit over the lens, or by having several eyeholes made in it to fit over the projecting screws of the camera; or, again, by having several strings or tapes fastened to it allowing it to be tied round the camera. From experience, I can say it is a good test of one's temper to try and obtain an accurate focus of some object when a strong wind is blowing and the focussing cloth seems to prefer any position but the desired one over the operator's head.
