PHOTOGRAPHY 119 



the small picture that results, and of course there was 

 a lot to be said against this, but now at least one 

 large well-known firm print enlargements by the dozen 

 at quite a nominal charge. In working out the actual 

 cost of production per dozen of these enlargements 

 from a small camera, it was found in one instance at 

 least that it was less than what the dozen could have 

 been produced for from a camera giving a contact 

 print equal in size to the enlargements, and no con- 

 sideration was given to the difference in the initial 

 cost of the cameras themselves, which is quite an item. 



Apparatus and Chemicals. — These small cameras 

 are not usually adapted for plates, but for all-round 

 general use they are not easily superseded, and the 

 intending traveller would be well advised to give them 

 his careful consideration. Having obtained the camera, 

 the next matters for consideration are the films and 

 plates, the necessary apparatus and chemicals. 



Films. — Where weights are the most important 

 factors, practically all negatives should be taken in the 

 film form : either pack or roll, according either to the 

 make of camera or the traveller's individual tastes. It 

 will, however, be generally found that the roll form of 

 film is the most useful, as not only is there somewhat 

 less chance of them sticking, but they are more easily 

 developed in the strip, especially where a daylight tank 

 is used. There is also far less chance of the films 

 being spoilt by fingermarks or scratches, due to 

 either inadvertent or careless handling.
