The problem of color cast has been plaguing photographers of digital photography. This problem is actually very simple, that is, the color of the computer screen can never be accurately displayed. Although many manufacturers have been committed to developing the latest color correction technologies, such as Apple's Coloursync and Kodak's PRECISION, experience tells photographers that the display still fails to display 100% accurate colors, which often constitutes for photographers. A lot of inconvenience in creation...
In fact, there are already some professional monitors on the market that can automatically detect the color tone and adjust the color value. Although it is still not completely 100% WYSIWYG (WYSIWYG), it is better than the monitor we usually use. In fact, these professional-grade monitors do provide users with greater color tone adjustment flexibility.
RGB tone display
Most of the monitors currently on the market are designed as RGB displays. The principle is similar to that of TVs in our homes. They are mixed in three colors to produce other different colors. In addition, RGB (R red, G green and B blue) is selected. It is also mainly because RGB can display a wider color gamut and color tone than the CMYK four-color gamut of traditional printing, and the color tone is also relatively clear, so RGB is more suitable for colorful screen display. However, since many print media such as computers use CMYK (four colors, cyan, magenta, yellow, and black) to form a printing standard, many photographers need to convert the finished work into CMYK, but Some tones during the conversion process may exceed the original color gamut, making the color gray, and more likely to affect the printed color. So, every time a photographer really wants to convert a finished work into a print, many photographers, and even many home computer users, go through the process of converting RGB to CMYK (usually done in Photo-paint or Photoshop). Conversion), during the conversion, the problem arises... The best solution is..., experienced photographers tell us that they will pre-prepare Pantone color, using Pantone color as the standard, but, Pantone color From the screen, there is still a distance from the actual color tone on the color. Therefore, many photographers will use the experience to place the actual objects in front of the screen to make comparisons on the screen and on the output. Try to minimize the error.
It is also helpful to use Gamma color correction.
In addition, if you use Photoshop frequently, the built-in "Kama Gamma" setting in Photoshop can also adjust the display you use to the appropriate value, usually this value is 1.8, although 1.8 will really make your monitor look It's a bit dark, but this value really makes your monitor the closest color to the original photo. In addition, if your monitor is reddish or bluish, 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 product related to digital imaging, you often have a software that adjusts the color. After tuning, your scanner can scan the exact color, so your monitor is very needed. Do the adjustment. Because, the adjusted monitor, regardless of the color and even the contrast of the image and tone performance will be better. Summarizing accurate adjustments is very important for both graphic design and photographers. If you pre-adjust the monitor's hue when you start work, then the printed matter (whether you use a professional large press or ordinary inkjet) Printers, your photos and works will reduce the chance of color cast.
