What do you mean by color photos?

A color photo is a photo of a person or thing that is exposed under a photographic negative with photosensitive paper and then developed and fixed. It can clearly reflect the clear color of the predecessor or thing, and is called a "color photo".

Color printing is a photo printed on colored paper, and the printing of transparent film is not called color photo. There are two ways to take photos: negative positive and positive. Negative and positive printing is very cheap. It is easy to compensate color when printing, and it is mostly used for public printing and large-scale amplification.

In 180 1 year, British physicist Thomas Young (1777–1829) published his research on "color", saying that human eyes can have three kinds of "color perception" of visual nerves: red light, green light and purple light. Furthermore, nature is a mixture of three basic colors: red, green and purple.

Let us feel many, many different colors. In 1860, Maxwell (Maxwell1831–1879) studied color negative films, and took the lead in taking pictures of the three primary colors of red, green and blue, and then superimposed and projected them to form a color image.

This is the process of adding color, which leads to the principle that color TV can develop color. From then on, world photography began to move from black and white to color. That is, the rise of what people call the "color photography era".
