PHOTOGRAPHY, SCIENTIFIC ASPECTS 



In architecture, surveying, and map-making, the 

 camera has been put to much practical use. It is 

 fast replacing especially in mountainous countries 

 the plane-table as a means of obtaining accurate topo- 

 graphical maps. Architectural measurements are 

 obtained with great exactness from photographs. 



Into the conduct of law, photography now enters 

 in large part. Its applications are too numerous to 

 be mentioned here in detail, but its possibilities as 

 a means of information will be evident to anyone who 

 thinks a moment on the subject. The establishment 

 of identifications one of the most difficult matters in 

 criminal procedure; the detection of forgeries by pho- 

 tographic enlargements; the accumulation of indis- 

 putable descriptive evidence in all kinds of accidents; 

 the preservation of the exact conditions surrounding 

 the commission of crime, which may afterwards be 

 changed, such as the appearance of wounds, the loca- 

 tion of hand and foot prints; the relative position of 

 furniture, etc.; the collection and dissemination of 

 criminals' portraits these are but a few of the ways 

 in which photography is employed by every well- 

 policed nation. Truly may it be said that in every 

 department of human activity "the sun brings all 



things to light."
