Color photography should incorporate every color we see. What are the three main colors?

Color is the basis of photographic composition. This is actually the base before everyone yelled at me. Colors can improve our photos, depending on how we use them. But how do we know which colors can match? Should color combinations be avoided?

If you are confused about the relationship between colors, it is very useful to look at the color wheel. The color wheel is a circular pattern, which intuitively represents the relationship between colors.

As far as photography is concerned, primary colors are the foundation. Red, green, blue and their combinations will give us all colors. They are also the basis of our camera sensors-any pixel can capture red, green or blue light. The amount of red, green and blue captured by these pixels and the fact that they are closely combined are how our camera generates colors in digital images.

In post-production, the way we deal with colors is mostly based on red, green and blue. Color profiles for cameras, screens and printers use red, green and blue. This is also one of the ways that we define absolute color with RGB values. No matter what software we use, these numbers all show the same color.

Only primary colors can provide impressive color contrast for our photos. However, when we mix auxiliary colors, we will get more creativity.

In the initial stage, the simplest method is to use three photosensitive elements to image red.

Color, green and blue photosensitive elements have been used for CCD photosensitive. After the light is split by the prism, the three colors are mapped to the photosensitive elements of the three colors respectively. The last three signals are combined into one color, which is the color image we see. Many transmission cameras using this technology are marked with 3CCD on the side of the fuselage.

Bayer filter is widely used at present. Three red, green and blue filters are used to cover the photosensitive element. In groups of four, the series consists of red, green, blue and green. The human eye is more sensitive to green light, so there is another green light. Each color filter can filter out the corresponding color, but the effect of this method will be a large number of mosaic arrays. How to form a complete color?

This is mainly through the similar color, through the algorithm to guess, according to the similar color information to guess the number of other two colors except their colors, thus generating the original signal and forming the color signal.

As for guessing the color, it is the patent of the chip company. Even for the same chip, the color algorithm is different and the color is different, which involves the chromatics of various companies.

If it is original, there will be green images with low saturation and more mosaics. You can get a more authentic image from Derbyl.
