What's the difference between developing and developing digital photos?

One: the effect is obviously different.

Digital photo printing is directly printed on photographic paper by inkjet or laser, but it is easy to get stained with paper and fade. The image effect is not as good as that of development.

Washing is to develop photographic paper with liquid medicine and professional equipment. The picture is smooth, the effect is clear, the image is delicate, the color is true, there is no graininess at all, and the color retention effect is more lasting.

Two: different materials.

The surface of printing photographic paper is coated with red, green and blue photosensitive dyes, and the paper base of printing photographic paper is generally white. There are many kinds of printing materials, such as ordinary photographic paper, gold paper, silver foil paper and other metal paper.

Three: different storage time

The developed photos can be kept for a longer time, and the printed photos can be kept for a shorter time. This is because inkjet is used for printing, and inkjet can be kept for a shorter time.

Four: Efficiency and cost are different.

Digital washing equipment is commercial equipment suitable for mass production, which is suitable for mass washing, with high efficiency, less consumables for professional large-scale equipment and low average cost. But if it is a small number of photos, the cost of printing is higher than that of printing.

There are many photo processors, which are generally relatively small, but if the printing volume is particularly large, the printing speed should be considered. From a security point of view, photo printing is safer and more reliable. It is cheaper to print a small number of photos, but if you print a large number of photos, the average cost is high.

Five: the principle is different.

Printing photos is a process of chemical reaction, while printing photos is a process of physical reaction. There are essential differences between them.

Extended data:

Photo printing: The first photo that can be preserved for a long time in human history was born in 1837. It is a permanent image formed by a kind of silverplate photography invented by Frenchman Daguerre. Since then, orthodox photos-silver salt prints have sprouted and grown. And constantly improve, after nearly 200 years of development, the most precious images in human history are preserved in the form of silver salt prints, which have stood the test of time and proved the irreplaceable quality of silver salt prints.

Photos are developed with light as a brush, with natural, delicate and realistic colors, excellent clarity and reproducibility, and stable images. It is widely used in various images left by residents in daily life, travel and parties. Group photos kept by schools, institutions and units; Wedding photos taken by couples when they get married; Handle photos of various certificates; Precious pictures taken by professional photographers and journalists.
