What is the imaging principle of color photos? Can you make it change color?

I had a brief look. The first is the effect of the camera itself: 1, the aperture of the lens is small, and the curvature of the front lens is not large, which leads to obvious loss of light in the corners of the picture, which is the taste of "dark corner". 2. The number of lenses is small, the structure is simple, and the material is simple, so the aberration correction is not very good, and the imaging is soft (fuzzy). 3. There is no need for strict manufacturing quality control and strict sealing effect. Strip-shaped light marks or spots 4 can be generated on the negative. In order to fully express the atmosphere and artistic conception of the picture with the help of color, the flash comes with a color filter, which can make the flash have a certain color, and the main body of the picture will have a color cast ... Then there are factors about the film, such as 1, any commonly used film can be used. The most commonly used film is expired film, because expired film is cheap. 2. In order to pursue a strong effect, the volume of Agfa is often chosen. When it is red, it is violent, strong and bright. This is probably the mutual fulfillment of the film and LOMO's personality. 3. negatives are often used. The development of film itself is a matter with many variables, and the same film can adjust completely different effects. You can refer to some works by Mika Ninagawa. 4. There are some very special choices when developing darkroom, which can be regarded as the filter effect of film age-negative film and positive film, etc., which will also bring special effects. Some notes: 1, LOMO was made in Leningrad before. As we all know, the quality control of Russian equipment, the lens that has just left the factory may have a lens group for you to install backwards. LOMO, a light-leaking gadget, has the most love. Later, it was transferred to China Phoenix Optical Production, and our quality control ... should be between Hehe and Hehe. 2, LOMO is low cost, good mood, and no one uses bottom scan to see the picture quality, you can use any expired film. Anyway, the film exposure will be fine for a year or two ... Now a box of low-sensitivity amateur film is about 10 yuan (Shanghai Starlight), which seems a little expensive to play ... 233333, just for fun, don't use reverse film. The reverse film is too careful and meticulous ... what's more, it's a problem to put a roll of reverse film in with LOMO metering, and whether you can take photos that you can see. In contrast, the film has a larger tolerance (in fact, no one cares whether you are black or white, it's all taste ...), and the development is highly adjustable, and ... the development cost is low. Besides, the development of LOMO is irregular, and the film is more affordable. 4. The positive effects of negative films can still be seen on today's digital models, such as Ricoh ... I think it's quite good. ...
