The difference between black and white photos and color photos
Only two potions are needed to develop black-and-white photos manually: developing and fixing. You don't need to pay attention to the temperature of the potion in summer, but you need to add hot spots in winter. Handmade black and white is about exposure time, depending on the thickness of the film, not that everyone can take pictures with medicine. You must develop the color photos by machine, because the paper with color enlargement can't see any light at all. Different black and white papers can see red light. When the color enlarged paper sees the light, the photo is a mass of black. Generally, there are at least three kinds of potions to be used for color development: color development, floating and stability; And whether it is summer or winter, the liquid medicine can only be developed at a certain temperature. Color photos cannot be developed by hand.
