| Abstract: | The author reports on a number of specific applications of photography in medicine for which the normally available lenses for amateur cameras do not suffice. To begin with, the problems involved in ultra-violet and infra-red photography are dealt with. In ultra-violet photography the spectral transmission of the lenses is of importance whereas in infra-red photography the chromatic correction is decisive. Further, attention is drawn to the rble stereo-photography is playing in medical tuition. To conclude, the reasons are given for the superiority of lens-optical systems in radiography. |
