How to tell whether a photo is developed or not?

Whether a photo is printed or developed can be distinguished from clarity and color, storage time and water resistance.

1, distinguished from clarity and color.

The cleanliness of printed photos is relatively worse than that of printed photos, and the color of printed photos is also worse than that of printed photos. In addition, printing is not easy to fade, and printing will fade more easily.

2. Distinguish from the storage time

Generally, printed photos will be kept for a short time, but it depends on whether they are printed with inkjet or pigment ink. Generally, inkjet storage time is short; Printed photos are generally kept for at least 50 to 200 years, of course, this also needs to be combined with various conditions.

3. Different from waterproofness

Printed photos are prone to water stains, and printed photos clean up the water in time without much damage. Of course, it also depends on the quality of photographic paper, whether there is coating, plastic packaging and so on. These conditions have a great influence on the preservation time and waterproof of photos.

Extended data:

The difference between photo printing and developing:

First of all, the effect is different:

1, water washing is developed on photographic paper with liquid medicine and professional equipment, which is similar to the feeling of laser phototypesetting. 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.

2. Printing is directly printed on photographic paper by inkjet or laser, which is easy to print paper and the image effect is obviously not as good as that of digital printing. As for the life of ink, it is not as good as the life of development.

Second, the storage time is different:

Printed matter has a short storage time, usually its color turns yellow and brownish white after half a year, especially the fading of black is the most obvious.

1. After developing the photos, the film should be post-processed in the darkroom. Post-processing includes film processing, photo printing and cutting. Learn photography, understand and master the basic skills of darkroom operation.

2. The output quality of photo printing is not only related to the performance of the printer itself, but also related to the quality of the original printed image. The printing effect of low-resolution digital photos will certainly not be much better. It is suggested to ensure that the picture resolution is above 1280× 1024 pixels.
