What are the advantages and disadvantages of digital photography compared with traditional film photography?

Advantages and disadvantages of traditional film photography and digital photography;

1) resolution

Different photosensitive elements have different resolutions, and different films have different resolutions. According to Roger N. Clark's analysis, according to different types of 35mm film, it is about 4 million to 6.5438+0.6 million pixels, such as Fuji's Provia 100 is about 7 million pixels, Velvia 50 is about 6.5438+0.6 million pixels, and the current SLR.

2) Noise/particles

Film particles come from chemicals, and digital noise does not need electronic information. According to Norman Koren's research, if the sensitivity is the same, the digital noise of the current technology is much smaller. However, in terms of long-term exposure, because the digital camera may produce a lot of noise due to overheating of the fuselage, the film is not afraid of this.

3) Dynamic range

The dynamic range of most Kodak films is about 13, while that of current digital cameras is about 14, and that of more advanced films such as D8 10 is 15. Moreover, many digital cameras have HDR function, which can take photos with dynamic range far exceeding that of film through peripheral exposure.

4) Film speed

The common film sensitivity is 100 to 3200, and there are also high-speed films such as 6400. However, digital cameras such as D4s can shoot exaggerated figures such as ISO 409600, and the sensitivity can be freely changed. Unless the outsole cameras are shot one by one, the whole roll of 135 film is the same and cannot be changed halfway. Although film can push several exposure levels, there are still some limitations.

5) Cost and convenience

Digital photography is expensive to start with, and the technology changes a lot every few years, but convenience and immediacy are obvious advantages, and even the capacity is so large that you don't have to be afraid to change the memory card for three minutes.

Film photography is cheaper to start with, and the fuselage can be used for a long time. Usually, consumers will buy films and develop and scan them. But the convenience and immediacy are obviously weak, and there are fewer and fewer places to print.
