(2) to determine the exposure time approaches
medicine R&D experience in France: In addition to very experienced people, in general, should not be used.
medicine photo test method: This is a simple, easy, accurate, and reliable way to determine the exposure time. Method is to use the same sample under the same conditions, according to geometrically increase the exposure time looks different exposure time of trial photo negatives, after imaging and fixation, based on the negative circumstances to determine the correct exposure time.
Sigma-Tau Pharmaceuticals meter method: microscopic photography light meter that can be used There are four types: â'ˆ handheld photoelectric photometry; new drugs R&D photomicrography using photoelectric light meter; â'Š micro-camera device built-in or external automatic exposure control table; medicine researchordinary camera mounted inside the meter. The first two can be common, but not precise enough, the latter two kinds of convenient and accurate.
