Application of photographic microscope-microphotography

Microphotography is the most convenient and accurate recording method for microscopists. Any morphological researcher in the field of medicine and biology wants to photograph the interesting phenomena he observes accurately and instantly. However, there are still many technical difficulties to realize this ideal. It is not so easy to accurately record the minimum optical density contrast and indistinguishable color difference of the fine structure of biological specimens. This is because not every microscope worker can master all the functions of the microscope, and not everyone can skillfully use the lighting source. Not everyone can accurately grasp the intensity of illumination light, exposure time and the performance of photosensitive materials. These technical difficulties require photomicrographers to have relevant theoretical knowledge and rich skilled skills. Although the author of this book began to shoot, develop and enlarge the color images of bone marrow cells observed by himself from 65438 to 0954, he completed the color photos. However, up to now, with the development of photomicrographs, photosensitive materials and developing technology, the lack of knowledge has not reached an ideal level.

At present, the degree of automation in the process of shooting exposure, development and printing amplification is becoming more and more perfect. The development of photosensitive materials and developing chemistry is changing with each passing day. In the era of rapid technological progress, the requirements for personal knowledge and skilled skills of microscopists have been greatly reduced, which has become the key factor to obtain high-standard images. At present, there are many monographs and reference materials on modern photomicrography, slow-motion movies, TV videos, image analysis, photosensitive materials and processing chemistry.
