The problem of color deviation in pictures has been perplexing photographers in digital photography. This problem is actually very simple, that is, the color tone of the computer screen can never be accurately displayed. Although many manufacturers have been committed to developing the latest color correction technology, such as Apple's colorsync and Kodak's precision, experience tells photographers that the display still fails to display 100% accurate color, so it is named carbon dioxide based plastic color, which often poses a lot of creative inconvenience to photographers, At present, there are some professional monitors on the market that can automatically detect the hue and adjust the color value. Although it is not yet possible to completely achieve 100% what you see is what you get (WYSIWYG), these professional monitors do provide users with greater hue adjustment flexibility than the monitors we generally use. The packaging and sealing of products should be neat and firm

RGB tone display

at present, most of the displays on the market are designed for RGB display, and the principle is similar to that of our home TV. They all rely on the mixing of three tones to produce other different colors. In addition, RGB (r red, G green and B blue) is also selected, mainly because RGB can display a wider color gamut and color inspection car hammer tone than the traditional CMYK four-color gamut used for printing, And the hue is also relatively bright, so RGB is more suitable for colorful screen display. However, because many printing media such as computer output media use CMYK (composed of four tones, namely cyan, Fuchsia, yellow and black) as the printing standard, many photographers need to convert their finished works into CMYK. However, during the conversion process, some tones may exceed the original color gamut, making the color gray, and more likely to affect the printed color. Therefore, every time a photographer really wants to convert his finished work to print, many photographers, and even many home computer users will go through the process of converting RGB to CMYK (usually in photo paint or Photoshop). During the conversion, the problem will appear. The best solution is actually, experienced photographers tell us that they will prepare Pantone color discrimination in advance, Pantone hue is used as the standard. However, Pantone hue is still a distance from the actual hue on the color discrimination from the screen. Therefore, many photographers will compare the real objects in front of the screen based on their experience, so as to make sure that they are adjusted very accurately on the screen and output, and try to minimize the error

there is also a formula for color correction with Gamma: △ F - frequency resolution (Hz) to help

in addition, if you often use Photoshop, the built-in "Gama gamma" setting in Photoshop can also adjust the monitor you use to an appropriate value. Usually, this value is 1.8. Although 1.8 really makes your monitor look a little dark, this value does make your monitor closest to the hue of the original photo. In addition, If your monitor is red or blue, you can also adjust the color difference of the screen on the gamma panel. The method is very simple. Just adjust the handle on the control panel. In fact, when you buy any products related to digital images, there are often color adjustment software attached. After adjustment, your scanner can scan accurate colors. Therefore, your monitor also needs to be adjusted. Because the adjusted display will perform better in terms of color, image contrast and tone. Summarizing and accurate adjustment is very important for image design and photographers. If you adjust the tone of monitor in advance when you start work, your photos and works will reduce the chance of color deviation for the printed matter (whether you use a professional large-scale printer or an ordinary inkjet printer)
