A higher gamma value has the same extremes of black and white as a lower gamma value, but it will produce greater contrast within that range. Gamma is the rate at which shades go from black to white. If you’re working with still images that you plan to print, the white point of 5000K (D50) is recommended, as it looks more like white on paper. This is also known as the native temperature of your monitor. If you’re working with video on an LCD monitor, the recommended white point is 6500K or D65. With modern monitors, the white point is the temperature setting (measured in degrees Kelvin) that determines the warmth or coolness of your whites. Cooler whites will have red, orange, or yellow tints. Just as the hottest part of a candle’s flame is blue, a hotter white will have a bluish tint. There’s no such thing as a purely white light. The first thing your software will do is ask you to specify your monitor type and target settings: Avoid shining direct light on your monitor, and make sure the ambient light conditions are similar to those when you perform color adjustments on your work.

Devices like the Datacolor Spyder and the X-Rite ColorMunki will measure the ambient light wherever you are and recommend optimal calibration settings.īefore beginning the process, let your monitor warm up for about 30 minutes. A colorimeter is a small calibration device that fastens to your screen and works with calibration software to optimize display color for your particular screen and your room’s particular lighting conditions. These programs rely on your eye, and eyes are subjective.įor objectively accurate color, you need to use a colorimeter.

Neither online calibration software nor the calibration tools that come with your Windows or Mac operating system will help you obtain accurate color. Since nearly every screen works on the RGB model, if you correct color on a properly calibrated screen, you’re giving your work the best chance at appearing how you want it to on other people’s screens. This model dates back to the nineteenth century, but it’s also the standard for most TVs and computers. Monitor or display calibration is the process of aligning your screen’s colors with the standards set by the RGB (red, green, blue) color model.
