What are the similarities and differences between traditional optical photography and digital camera photography?

Ha ha, to sum up, digital is more convenient than film, so it can be directly released to judge whether the exposure is accurate or not, and can be adjusted immediately.

Of course, the high latitude of film is beyond the reach of digital, and the high latitude and high sensitivity are absolutely excellent. In addition, the film color reproduction is accurate (this obvious nonsense) without photoelectric conversion, and the color is delicate. Therefore, although the photos taken by your favorite films are very tolerant, they will not feel gray at all, but the numbers are different. As soon as the tolerance comes up, the picture feels empty and the color is not saturated enough.

Well, in shooting, traditional cameras mainly expose themselves according to the photographer's own experience. Of course, traditional cameras can also meet the requirements of automatic exposure, but the requirements of multiple exposures or special effects for the same photo will put forward high requirements for the photographer's level. If it is a simple traditional camera, there is no operation. If it is a more advanced camera, there will be many dials like the current SLR, including manual film winding, manual focus ring, aperture adjustment, shutter time adjustment, including B gate and T gate, and aperture priority or shutter priority. These basic photographic parameters will not change. Some changes are the choice of film sensitivity. The automatic metering function of the old camera will let you choose the sensitivity. And digital ones can be changed automatically according to the environment.
