This will open up a tool that walks you through each step of calibrating your monitor. To find the calibration tool in a Mac, go to System Preferences > Display > Color > Calibration. (Photo by Ben Andrews) For Mac. Windows has a simple built-in calibration tool to get you started.This method doesn't require a color profile for your monitor, so it's ideal for casual use, or for when you're not at your own computer and need to make some quick adjustments.Click the Use this device as the primary monitor checkbox. At its core it relies on ArgyllCMS, an advanced open source color The easiest (but least accurate) way to calibrate your display is to simply adjust its brightness and contrast settings. DisplayCAL (formerly known as dispcalGUI) is a display calibration and profiling solution with a focus on accuracy and versatility (in fact, the author is of the honest opinion it may be the most accurate and versatile ICC compatible display profiling solution available anywhere).

If you've followed the previous calibration, now your mid-tones will be reproduced roughly at the shade intended. You will likely not need to have your display at its maximum brightness if the room isn't too bright, if the display isn't back-lit (such as in front of a window) and if the display isn't too old.(2) Highlight & Shadow Detail.
Best Color Calibration Tool Software Will AskThis ensures that its brightness and color balance have reached a steady and reproducible state.Just before the calibration starts, your calibration software will ask you to specify several parameters that it will calibrate to (the "target settings"). Special software then controls the monitor so that it displays a broad range of colors and shades underneath the calibration device, which are each sequentially measured and recorded.Common calibration devices include the X-Rite Eye-One Display, ColorVision Spyder, ColorEyes Display and ColorMunki Photo, amongst others.Before initiating a calibration, first make sure to give your monitor at least 10-15 minutes to warm up. It is usually something that looks like a computer mouse, but it instead fastens to the front of your monitor. This usually involves changing various physical parameters on your monitor, such as brightness from before, in addition to creating what is called a Look-Up Table (LUT).The LUT takes an input value, such as green=50 in the above example, and then says "on 'Monitor X,' I know that it reproduces green=50 darker than the standard, but if I convert the 50 into a 78 before sending it to the monitor, then the color will come out how a green=50 was intended to be seen." An LUT therefore translates digital values in a file into new values which effectively compensate for that particular monitor's characteristics:A monitor calibration device is what performs the task of both calibration and profiling. However, this isn't always possible, so the process of monitor calibration actually requires two steps: (1) calibration and (2) profiling.(1) Calibration is the process of getting your monitor into a desirable and well-defined state. A digital green value may therefore appear darker, lighter or with a different saturation than this color was intended to be seen:Note: for the purposes of this example, "standardized color" is just one example of a desirable state that is well-defined in terms of universal parameters, such as gamma, white point and luminance.Ideally, you would get your monitor to simply translate the digital values in a file into a standardized set of colors.CALIBRATION SETTINGSHere's a brief description and recommendation for each of the target calibration settings:White Point. If neither are perfectly achievable (they never are), then the software tries to prioritize so that inaccuracies only correspond to tonal and color differences that our eyes are not good at perceiving. Sophisticated software algorithms then attempt to create an LUT which both (i) reproduces neutral, accurate and properly-spaced shades of gray and (ii) reproduces accurate color hue and saturation across the gamut. During the calibration process you may also be instructed to change various display settings, including brightness and contrast (and RGB values if you have a CRT).The result will be a matrix of color values and their corresponding measurements. For this reason, it's generally recommended to leave your LCD at its default color temperature unless you have a good reason to set it otherwise. Any deviation from this native value will end up reducing your display's color gamut. While many LCD's have a color temperature option, the back light for these displays always has a native color temperature. However, with LCD monitors it's become a bit more complicated. If they were on their own, and were the brightest shade your display could show, then your eye would adjust and you would likely call each of them "white." See the tutorial on white balance for additional background reading on this topic.With CRT monitors, the standard recommendation is to set your display to around 6500K (aka D65), which is a little cooler than daylight. It strongly influences an image's apparent contrast:Unlike with the white point and gamma settings, the optimal luminance setting is heavily influenced by the brightness of your working environment. This makes a given image appear brighter and darker for lower and higher gamma values, respectively, but does not change the black and white points. This setting controls the rate at which shades appear to increase from black to white (for each successive digital value). Canon driver g2000 for macThe job of the LUT* is to maintain neutral gray tones with the correct gamma. However, you'd be surprised how often this isn't the case (see below). The LUT is usually loaded immediately after booting up into your operating system, and is used identically regardless of what your monitor is displaying.Whenever the red, green and blue values are equal, an accurate monitor should display this as a neutral gray. CALIBRATION: LOOK-UP TABLESThe Look-Up Table (LUT) is either controlled by your video card or by your monitor itself, so it will be used regardless of whether your software program is color managed — unlike with the color profile. Use the lowest setting in the 100-150 range where you can still see all 8 shades in the above image. The maximum attainable luminance will depend on your monitor type and age, so this may ultimately limit how bright your working environment can be.However, higher luminance will shorten the usable life span of your monitor, so it's always better to instead move your monitor to somewhere darker if you can.
