COLD, HUNGRY AND SHY. 



fishing, hunting, automobiling, athletic games 

 of every kind are desired, and they should 

 be as topical as possible. 



6. Packages containing photographs should 

 be marked "Competition," and must be fully 

 prepaid or they will not be accepted. 



7. All competitors must be prepaid sub- 

 scribers. 



First competition will close June 1, 1905. 



The object of these competitions is two- 

 fold. We want to interest our readers in the 

 use of the camera as their weapon of sport. 

 The hunting of animals or birds in their 

 native woods ~vith a camera in the hand, is 

 just as exciting ^nd sometimes more dan- 

 gerous than when armed with a shotgun or 

 rifle. This, then, is one of our purposes. 

 The other is to obtain suitable photographs 

 of out-door life for our own pages. These, 

 of course, we want to be timely and expres- 

 sive of the season of the yt 3 r. We do not 

 want skating or football pictures in the sum- 

 mer months, for instance. 



If we find the interest in these competitions 

 is keen, we shall increase the number and 

 value of the prizes. It all depends on our 

 readers themselves. 



Some photographers are always in doubt 

 as to when to stop development of their 

 negatives. They may be able to expose

correctly, but when in the dark-room they 

 are unable to judge of the density of the 

 . image, and either do not develop far enough 

 or else so far that the delicate half-tones 

 get all blotted out. For such, and, in fact, 

 for all, we recommend the use of the Wat- 

 kins time or factorial method of development. 

 This method, once learnt, is very simple and 

 most effective. It is the coming method of 

 development with all photographers. It is 

 based on Mr. Watkins' discovery that there 

 is a certain fixed ratio between the total time 

 it takes a developer to fully develop a plate 

 and the time that elapses after pouring on 

 the developer, before the image begins to 

 appear. For instance : Suppose we take a 

 plate that is exposed for one second on a 

 subject and use ortol as our developer. The 

 image begins to appear in say 30 seconds 

 after pouring on the developer and the re- 

 quired density is obtained in 300 seconds, or 

 10 times 30. The ratio for this developer is, 

 then, 10. This is called the factor. Now 

 take another plate exposed on the same sub- 

 ject for say 6 seconds. The image begins 

 to appear in 25 seconds. Multiplying 25 by 

 the factor 10, we get 250 seconds. Taking 

 the plate out of the developer at the end of 

 250 seconds, then, we shall find that it is 

 almost identically the same as the first plate.
