Film is still available in the market, but it is really hard to buy, because with the development of science and technology, digital cameras and most mobile phones have the function of taking pictures, and the price is low, so few people choose film camera brushes.
Film, also called negative film, is an imaging device. At present, the widely used film is coated with silver halide on the basis of polyacrylate film, and it is very soft and easy to use when rolled into a whole roll.
