How should I shoot black and white negatives? What makes a better black film

The main reason for learning photography with black and white negative film is that black and white negative film is the cheapest of all films. Take Lucky SHD100 black-and-white film, which is familiar to the majority of photographers, for example, the wholesale price of each 36-sheet package is only about 5 yuan, and the quality is relatively reliable. In addition, shooting with black and white negative film will have more hands-on learning opportunities, which can enrich the film sensitivity, sharpness, graininess, gray and fog, as well as density, contrast and other perceptual understanding, so as to leap into the rational understanding of a comprehensive approach to mastering photographic techniques.

With good black and white negative film there are four main points:

One, photographic exposure and film processing black and white negative film photographic exposure and color photography exposure was not a big difference, just black and white negative film in their own hands in the processing of processing can be convenient according to the requirements of the special development process, so the photographic exposure also has a special significance. For example, in order to improve the contrast of the image taken on a cloudy day, when shooting, intentionally underexposed, developing intentionally delayed development; in order to reduce the contrast of the hot sun under the illumination, intentionally increase the amount of exposure to reduce the development time ...... can be obtained according to the requirements of individuals need the contrast, from this point of view, black-and-white photography has more initiative than color photography.

Black-and-white photography is more active than color photography.

Black-and-white negative film processing to be more important than the photographic exposure, many beginners fail mainly because of the failure to grasp the essentials of the development.

Developing black-and-white negative film used to show, fixed potion formula generally do not easily change, such as developing formula fixed with D-76, fixed formula fixed with F-5, so that you can get a more stable processing results. In obtaining a certain amount of experience in processing and then try to use other formulas to process film, in order to reduce the blindness brought about by the mistakes.

The density, contrast and granularity of the negative are directly proportional to the development time, temperature and stirring speed, so you should adhere to the time, temperature and stirring.

Two, the use of filters in landscape photography, in order to darken the blue sky, rendering brilliant white clouds, yellow and red filters are essential. The use of yellow and red filters need to increase the exposure of one and two levels, respectively, which in the small aperture hand-held camera shooting, will increase the negative impact of "hand shock", so the use of the above filters with a small aperture shooting, should be as much as possible to more than a tripod, in order to obtain sufficient clarity.

Photographs taken with a large red filter will have a greater contrast, the blue sky looks like night ...... with artistic exaggeration. Photographs taken with a medium yellow color filter have a contrast close to the visual. The above two filters should be selected according to personal preferences, but in the shooting of portraits, in addition to women, children, it is best not to use the above filters, so as not to pale skin color, weakening the normal texture.

Three, the purchase and storage of film In order to achieve a more stable shooting results, as far as possible, the use of the same batch number of film (first buy a trial, feel the quality of no problem and then go to buy some more of the same batch number of film storage use).

The same batch of film is the same brand production date or expiration date, the emulsion number is exactly the same film. From an economic point of view, the wholesale price is about 20% lower than the retail price, the general stores sell film to 10 rolls of wholesale, a wholesale 10 film, for the average enthusiast, in the expiration date (usually within two years) is able to use up. Of course, you should pay attention to the expiration date when you buy film. If it is estimated that the purchase of film can not be used up within the expiration date, then it can be placed in the refrigerator refrigerated storage, in the -10 degrees below the low temperature storage, even if the storage time is longer, the film "expired" for a period of time, its photographic properties will not have significant changes, is still good to use. However, it should be noted that the storage must be sealed in the original packaging into the refrigerator, want to use the film will be removed, placed at room temperature for a day before unsealing, otherwise it will be due to condensation and seriously affect the use of water, the camera will also be seriously damaged.

Four, the photo of the magnification of the production of a variety of factors, the development of black and white negative density, contrast is difficult to ensure complete consistency. Different contrast of the negative in the enlargement of the photo if you only use the same kind of contrast of the paper and the same kind of developer, the production of the contrast of the photo can not be consistent, which requires a different contrast of the paper to match the production of the law: the negative contrast is small selection of large contrast of the paper; the negative contrast selection of small contrast of the paper. It is recommended to prepare two kinds of contrast paper No. 2 and No. 3, basically able to handle the requirements of different contrast negatives to produce photos. Of course, on hand only a contrast number of paper, you can also use different contrast developer to adjust the contrast, but in contrast to some of the cumbersome, not to say more here.
