CHAPTER VII 



SIMPLE PHOTO-MICROGRAPHY 



The average person seems to be under the impres- 

 sion that the photography of microscopic objects 

 is a comphcated business, involving great skill and 

 the use of elaborate and costly apparatus. It is 

 quite true that photo-micrography in some of its 

 branches can be undertaken only by a skilled worker 

 prepared to spend some money ; but, generally 

 speaking, the individual who knows how to use 

 a microscope, and has a working knowledge of 

 photography, can produce good photo-micrographs 

 with simple apparatus and at little expense. Low- 

 power photo -micrography is comparatively easy ; 

 the process becomes more difficult in operation with 

 the use of increasing powers, which involve greater 

 care in focussing and illumination. The photog- 

 raphy of hve objects is fraught with many diffi- 

 culties, the chief among them being that of exposure, 

 which must be very short if movement is not to be 

 recorded — generally too short for any but special 

 illumination. But low-power work in connection 

 with fixed objects is the most common, and is 

 certainly weU within the reach of the ordinary 

 amateur worker.
