CONVENIENCES FOR TRAVELLING.
The landscape photographer is fre quently, when at a distance from home, desirous of some convenient method of changing plates. In such cases, a chang ing bag, of the type shown by Fig. 641, will prove very useful. As will be seen, the arms are introduced through two sleeve-like openings provided with elas tic loops at the ends to exclude light. The dark slide and plates are inserted in the bag, and changing is effected by touch. This is very simple after a little practice, but for those who prefer to see what they are doing the pattern illus trated by Fig. 642 is obtainable. This is supplied with a leather eye-piece fitted with ruby glasses and has a window of ruby medium. Both these changing bags are extremely light, and occupy remark ably little space. Fig. 61:3 shows a port able developing and changing box, with openings for the head and arms. A compact and practical developing cabinet, fitted with sink, waste-pipe, etc., and well adapted for use in hotels or lodgings, in any room from which the light can be temporarily blocked, is shown by Fig. 611.
Travellers of less luxurious inclination will find a folding triangular lamp of ruby glass of the kind illustrated by Figs. 645 and 646 suitable for any emergencies. It can be conveniently carried in the pocket.
the hand camera, since it is probably in landscape photography, and some closely allied branches, that the latter finds its principal employment. The points to which attention should be chiefly directed The necessary chemicals should preferably be obtained in tabloid or compressed form. These, with two or three celluloid in choosing a hand camera are the rapidity of the lens, the effective working of the shutter, and the clearness and developing dishes, fitting inside each other, will readily go in a moderately large camera case or satchel, leaving plenty of room for the apparatus itself.
