What Display Color Profile To Use For Video Mac
Apple tv app for mac. Mar 10, 2014 The correct profile to select in the Mac display preferences is the one that matches your display exactly. The one marked 'Color LCD' is the generic factory profile for the monitor and it is the best starting point, but I don't think it's tuned for each specific Mac coming off the line.
Photoshop and Your Monitor Photoshop displays everything through your monitor profile. If your monitor profile doesn't accurately describe the actual behavior of your monitor, your judgments about your images won't be accurate, which means your corrections will also be inaccurate. We're guessing that's not what you want. Photoshop uses the monitor's profile to transform color data on the fly as it gets sent to the video card so that the monitor displays the color correctly. The great benefit of this approach is that it makes it possible for people using very different monitors on different platforms to view the same image as consistently as possible. This makes monitor calibration a mission-critical necessity!
(The only time this behavior doesn't happen is if you set the working space to Monitor RGB, which we don't recommend.) To make this magic happen for you, you need an accurate profile for each monitor. To display color accurately, Photoshop needs to know how your monitor behaves—what color white it produces, what sort of tonal response it has, and what actual colors it produces when it's fed pure R, G, or B. Photoshop gets this information from the display profile. Although a default display profile is assigned to your monitor by your operating system, you'll get the best results from a profile customized for your specific monitor. Color Settings and the Color Picker Why are we talking about the Color Picker in this chapter? Mac boot linux usb.
Simply put, a great many people overlook the fact that the Color Picker is subject to the choices you make in Color Settings, because the numbers that appear in the Color Picker for all the color modes other than the current document's mode are the product of color-space conversions made using the default profiles, engine, and rendering intent. We've lost count of the number of e-mails we've received from confused users who tried to specify black as 0C 0M 0Y 100K in an RGB document and then got bent out of shape because: • The resulting color was dark gray.
• It picked up a bunch of C, M, and Y on conversion to CMYK. Well, 100K isn't black, because black ink isn't perfectly black or perfectly opaque—if it were, we'd never need to lay down more than 100 percent total ink. If you specify 0C 0M 0Y 100K in the Color Picker and then look at the RGB values, or at the Lightness value in Lab, you'll find that they aren't zero. And unless your CMYK working space uses maximum GCR, 0C 0M 0Y 100K isn't a 'legal' value for a converted RGB 000 black—you'll almost always want to add some amount of CMY to increase the density. The Color Picker is governed by two simple rules: • The 'real' color being specified is represented by the numbers relevant to the color mode of the current document, which may not be the numbers you're entering. If you enter CMYK numbers while working on an RGB document, the color you're actually specifying will be represented by the numbers that appear in the RGB fields, and vice versa. • When you specify color in a mode other than the document's, the actual color is calculated by taking the color values you entered and converting them to the document's mode using the working space profile for the mode you specified as the source profile, the document's profile as the destination profile, and the rendering intent specified in Color Settings.
When you think about it, it's hard to imagine how this could work any other way, but how may of us think that way in the Color Picker? TIP To see which monitor profile Photoshop is using, choose Edit > Color Settings, click the RGB pop-up menu, and look at the Monitor RGB command. Photoshop always uses the monitor profile used by the operating system. In Mac OS X, this is in the Displays preference; in Windows it's in the Display Properties control panel. You also have to maintain your monitor profile. Monitors drift over time, and though LCDs tend to drift much more slowly than CRTs, a profile that was accurate when it was created may not be accurate a week or a month later. Professionals whose jobs depend on accurate color may decide to update their monitor profile every week or two; some people go for a month or more before updating the profile.
