Why does documentary photography need black and white?

Of course, news or documentary photography does not have to be black and white, but there is no doubt that black and white is suitable for news or documentary subjects. Remove the color, leaving only black and white, to help the audience get rid of those useless details and get to the essence of the event, which is also needed for news or documentary themes. On some occasions, the light and social environment are complicated, and black-and-white film dominates the whole country. In the case of light-dark ratio, the tolerance of digital camera or color film is limited, and it is impossible to record light and dark content at the same time, while black and white film is competent with its great tolerance; In some conflict core areas, photographers are required to snap shots and TOU shots, which is difficult to accurately expose. Black-and-white film can also be remedied by extremely strong post-production (PS is inferior to traditional darkroom in this respect). In fact, there is nothing difficult to understand. In a word, it is necessary to use it.

The essence of documentary photography is true, accurate, rigorous and systematic. The art of black-and-white photography lies not in beautiful pictures, beautiful lines and gorgeous colors, but in courage and persistence, which is the essence of documentary photographers. In addition, black and white photos are more suitable for various occasions and more comprehensive records than color photos. For example, black and white photography can express the color world; The soft and hard tone of the picture, the virtual and real focus, the length of the focal length, the brightness of the light, the level of the angle, and the warmth and coldness of the color will change the modeling effect at any time according to the creator's ideas, which all provide hypothetical and creative possibilities for the photography art.
