Hardware calibration is more expensive, but correspondingly more accurate, than software calibration If your work is color-critical, there is commercial hardware for monitor calibration to suit every wallet size PANTONE offers an active calibrator called huey; the entry-level edition is about $80 and the tiny, unobtrusive hardware unit updates your monitor s settings as light changes throughout the day Also check out www

Now that you ve calibrated your monitor, it s time to tell Photoshop how to use a color space for your imaging work A fair analogy is that a color profile which you just created for your system devices is a set of instructions on how to build a house, whereas a color space determines how much real estate you have upon which to build your house Choose Edit|Color Settings By setting up color consistency and warnings, as described in this section using the Color Settings dialog box shown in Figure 4-1, you ensure color consistency and high-fidelity output when editing images The first thing you might notice is that if you own more than one Adobe product (such as InDesign and Illustrator), you ll see one of two icons at the top left of the dialog box

If this is your maiden voyage with color management, don t worry if you see the not synchronized icon, telling you that you re not using consistent color management between Adobe applications If you ve used color management in the past with other products, and you see the not synchronized, the following section describes how to get everything in sync Once you ve made and saved color settings, you can synchronize your color settings within the Adobe applications by setting and saving the color settings in one application and then choosing to use them in another Applications made by companies other than Adobe sometimes can read and write color profiles, and many of today s inkjet printers understand ICC profiles

Photoshop will operate flawlessly if you tell it to use large color spaces in which to edit your images When changing colors or brightness in images, you really need a large working space, because from moment to moment your edits are stepping outside of the default color space for an image file It s a similar theory to mixing a drink in a glass: if you have plenty of room in the glass (color space), you re less likely to spill any liquids outside of the glass while mixing The metaphor of outside the glass is color gamut, the available digital space for color expression in an image The following steps show you how to set up a color space for Photoshop to recognize and use:

1 Choose Edit | Color Settings to open the Color Settings dialog box (see Figure 4-1) 2 In the Working Spaces area, choose Adobe RGB (1998) from the RGB drop-down list

Usually, it s best to work with an image and save an embedded color profile using the broadest possible color space The sRGB color space is smaller than Adobe RGB and, as a consequence, some colors are clipped out of range if you work in this space, which is good for web posts but not for hi-fi imaging If you own a wider color space setting than Adobe RGB (such as ProPhoto RGB or Bruce RGB), choose it instead

If you re printing to a home inkjet printer, you do not need to, or want to, print a CMYK version of your RGB image Most of today s even moderately priced inkjets take RGB information and perform a better conversion than can be achieved through manual conversion In fact, a CMYK mode image usually prints to inkjet with less color fidelity than an RGB image, even though the ink cartridges are CMY and K
