The advantages and disadvantages of traditional film photography and digital photography are analyzed.

Film can be used as a large negative. At present, the commonly used landscapes are 6cmx6cm, 6cmx9cm, 6cmx 12cm, 6cm* 17cm, 4x5 (inch) and 8x 10 inch. At present, it is possible to digitize 6x6 (the price is 200,000), but it is 6 17 cm. If you really want to make such a large photosensitive element, the price is estimated to be hundreds of millions (US dollars). The United States commissioned Kodak to make a super-large photosensitive element, with multiple CCD chips, the size of Supor's pot cover, which was used for space telescopes. However, the cost of such a large film is only 100, so landscape photography is completely in the world of large format, which cannot be replaced by digital at present and may not be replaced in the future. However, in small cameras, especially in the 135 system, digital plays an absolute advantage.
