ABSTRACT:
This invention provides a method of obtaining increased efficiency in implementing a medical photograph by allowing the practitioner to utilize a slower speed film which has a high response to the color red and hues thereof. According to the techniques depicted herein, a flash or beam of light which is generated by means of an ignition tube or a flash bulb is directed through a condensing lens which lens directs the beam of light in a concentrated area thus allowing the practitioner to obtain a greater depth of focus with a higher f-stop. This thereby enables one to utilize a slower speed film which film inherently possesses a better response to the color red.
