Science photos.

Scientific photos should also be included in amateur photos, because they are rarely taken by professional photographers. It is precisely in this field that multilayer materials have achieved an extremely serious and, at the same time, quite wide application. There is no scientific field, in which we would not like to preserve scientific achievements in the form of colorful documentation. Terms and requirements, that are placed on light-sensitive materials, are sometimes quite high. If we want to reproduce the colors, which is very difficult, we have a range of reversible materials available, however, with changing measurement conditions during the tests, the exposure times are difficult to repeat. Due to the, that in many cases, especially in microscopy, light meters won't help us, we have to do without them by making difficult exposures at different times determined by feel. In uncertain cases, we can make several exposures on black and white material, which we then quickly develop and then expose the appropriate color material after taking into account the differences in light sensitivity. At the same time, attention should be paid to the already mentioned contrasts of photographed objects. The color of the lighting should naturally be typical, using a standard light source, so e.g. sunlight or a Nitraphot lamp. For this purpose, we can also use anti-smoke foils or correction filters with larger dimensions, which give almost unlimited possibilities of aligning the color of light. Negative materials are much easier to use due to less light color requirements and a wider range of usable exposures. Due to the, that scientific photography is always about very accurate and detailed images, we should use ganglion films more often than 35mm.

In fact, none of the areas of color photography is so versatile and so rich in problems, and therefore so interesting, like science photography. It pays off to everyone, even a layman, delve into this field, It's just hard to find that way, which gives us a good overview of the whole issue. Starting with simple landscape photos, we can enter the field of science photography, if we treat it first with a geologist's eye. Naturally, we cannot think of trivial motives, but with typical geological formations, that we would like to obtain on colored materials, which are very valuable for research. Soil sections, with which we deal with work in mines or in gravel pits, they are so expressive even for the layman, showing the geological differences of the earth, that they might fill him with some fear of the past of many hundred million years and the nothingness of his short life. For geologists, the photos can also be used as reference material for studies. If we look up, then we will find quite a field to show off in the atmosphere. A blue sky with clouds of various shapes can be used as the subject of wide-angle photos, even with spherical mirrors, which can then be placed on the desk. The biologist will need color photos to make comparisons of colors and changes in the shape of the plants, which, during long-term research, grow in various conditions. Comparing them, he will be able to see many phenomena unknown to laymen.
