teriors or in flash-light work. You 

 focus wide-open and stop down until 

 your depth is attained. 



Purchasing an Anastigmat. 



The prospective purchaser of an an- 

 astigmat photographic lens is referred 

 to our advertising pages. Therein are 

 announcements from several opticians. 

 Every lens is first-class. (We will not 

 admit to our advertising pages any- 

 thing that is not first-class.) Some 

 camerists prefer one kind ; others, 

 another. It is largely a matter of in- 

 dividual preference. But you will do 

 the best work with the make that you 

 like best and feel is the best. There is 

 a bond of sympathy between a camerist 

 and his high grade lens. They work 

 well together if they like each other —

Putting on His Best Expression. 



Mr. John H. Davis, of Baltimore, 

 Maryland, sends a photograph, repro- 

 duced herewith, of a child photograph- 

 ing a dog. As an ordinary attempt to 

 snap shot a dog or, rather, of some 

 photographer to pose the child and the 

 dog, it would not be extraordinary, but 



the dog's expression and the poise of 

 his head are more than worth the en- 

 tire price of admission to our pages. 

 It is a remarkable example of self-con- 

 sciousness, or at any rate of an attitude 

 that gives the dog the appearance of 

 putting on his best expression for the 

 camera. That the dog held his head in 

 that position may have been a coinci- 

 dence, but even if it were, it surely is 

 well worth publishing as an unusual 

 coincidence. The photograph was taken 

 in Seattle, Washington. 



Don't Do It. 



"Photoisms" says : 



"Clean the lens. Clean it each time 

 you reload. 'Under-exposure' is gen- 

 erally due to carelessness in this re- 

 spect." 



Several magazines devoted to pho- 

 tography keep saying, "Clean the lens." 

 Don't do it. Keep it from getting 

 soiled or dusty. The surface of a fine 

 lens is far too delicate for constant 

 performance of the scrubbing act. The 

 anastigmats I use are in perfect condi- 

 tion and always have been so since 

 first received. Cap the lens after every 

 exposure and keep capped. Don't let 

 it get soiled. 



EVEN A DOG INSISTS ON CONSCIOUSNESS-OF-THE-CAMERA EXPRESSION!
