What needs plate-making and printing to complete the final work?

Photography: In photography, the negative film needs to be developed, enlarged and enlarged again before the image can be converted into a visible image. In this process, it is necessary to use different negatives and chemicals, and control the exposure time, development time and other parameters to obtain the required image effect.

Painting: In painting, artists usually sketch or sketch on canvas or paper first, and then make in-depth creation and decoration with paint or paint pen. In this process, it is necessary to control the amount of pigment, color matching, painting methods and other parameters in order to obtain the required painting effect.
