/kloc-What is the gray point of 0/8 degree? What is the dispersion of the photo?

Analysis:

You can click a standard gray point in all the photos you have taken, and the software will automatically adjust the RGB value of the whole photo according to this gray point, so as to make the colors of the photo harmonious and unified. If there are no standard grey spots in your photos, you can also use Kodak's standard grey board. If there is no gray card, find the lid of a plastic bucket full of Kodak negatives. This cover 18 degree is absolutely gray.

The phenomenon that polychromatic light is decomposed into monochromatic light with a single wavelength through a certain medium is called dispersion. The principle is-when polychromatic light (white light) enters a certain medium, it will produce ... it will refract again when it exits, and the difference in propagation direction will be greater. This is the dispersion phenomenon. The dispersion of photos produced by taking pictures is the dispersion of photos.
