They are big and small respectively. 135 has an overall height of 35mm and an image height of 24mm, so there is no definite length. The most common O format is 24 x 36 mm, and my home name is O, which is full-film dslr, which means 24 x 36 mm, and the overall height of 120 is 6 cm, and the length is uncertain.

Machine design department uses 135 to 135, 120 to 120. 135 machine can't use 120, fine machine can't use large area film pasting. Some 120 machines can use 135, and large machines can use fine O O as the negative. The negative was developed and I saw that O was a negative image. That is to say, the realistic light O is dark where it is, and the realistic red is green (relative color). Negative film, also called print film, is the main design purpose of photos, that is, the final requirement of photos. The advantage of O is large tolerance and large exposure tolerance.

The color of O is more prominent than that of negative film, but the tolerance is lower, so the exposure should be an O. Positive and negative films are divided into black and white and the same color, and black and white positive films are rare. In fact, both black and white negative films can be developed into positive films, plus the process of "inversion", but there are few potions. Black and white negative, color negative and color positive are different from each other. Black-and-white negatives are the simplest and can be diy. Color negative film and positive film of the same color are extremely sensitive to water O, ph and water temperature with high accuracy.

He is very serious about O, QC is very good at O, and some street shops are sent to pro lab, because O has little work, so it is difficult to do it by himself.
