On Traditional Black and White Photography and Digital Photography

I can only agree with some of the above two answers. First of all, film photography is now generally regarded as traditional photography, not a matter of age, but a customary name for the public. I may be a movie lover upstairs, but I dare not argue about anything, because there are too many arguments about the pros and cons of movies and digital. I just want to say a few facts. Make an objective comparison between movies and numbers. (This comparison is measured by the technical time period at the end of 20 10, because I don't know what it will be in a few years. )

Advantages of digital camera over film camera: 1, avoiding accidental errors and systematic errors in film development and amplification; 2, convenience, high speed and no deterioration; 3, the white balance is easy to be electrically controlled, and the electronic shutter controls the exposure more accurately when shooting; 4. It is easy to connect with a computer to process pictures, and the technology is updated quickly; 5. With the latest electronic shutter technology and single camera technology, the camera steel shutter and mirror vibration are gone; 6, the shooting cost is low; 7. The quality is good, which has surpassed the general negative film. Pixels are no longer an issue. I believe that one day development will surpass the resolution of film.

Disadvantages of digital camera compared with film camera: 1, the one-time investment cost is slightly higher; 2. The harsh environment (extremely low temperature, sandstorm) is unacceptable; 3. Poor performance in large contrast scenes and small tolerance (relative to negative film). Some low-end CCDs have purple edges under high light; 4. The resolution, color reproduction, contrast and other parameters are not as good as the reverse film at present; 5, the long-term exposure effect is poor, and some cameras don't even have this function, which is not suitable for low-light photography; 6. There is no retro graininess effect of film, especially black-and-white photography, unlike software simulation. There is no way, because the film has existed for so long, many people have feelings for him; 7. Congenital defects of 7.CCD and other photosensitive elements lead to inaccurate depiction of subtle parts of the picture (three-color synthesis technology: three small photosensitive blocks are used to sense the light colors in their respective areas, and then a color is synthesized. If the light is projected carefully and the resolution of the lens is high, it will be impossible to restore these detailed lights well, and even there will be mistakes. For example, if cyan light is cast on the red sensor block, blue light is cast on the blue sensor block, and green light is cast on the green sensor block, the CCD integrated light is cyan, but it is actually light cyan. Although there are CCD systems on the market that are similar to film photosensitive principle, the comprehensive effect is still not as good as film, which is not suitable for harsh picture requirements.

Generally speaking, digitalization is the future development direction. Film will inevitably be replaced in the future application field. But it is impossible to completely replace film. Just as the invention of electric light did not completely replace candles, candles have become a retro emotional tool. Haha's laughter ...
