Why you should work in RGB
In this lesson, you start and stay in the RGB (Red, Green, Blue) color mode. There are two reasons for
this: you find more tools that are available in RGB mode, and changes to color values in RGB degrade
your image less than if you are working in CMYK. If you were sending this image to a commercial printer,
you would make sure your color settings were accurate, do all your retouching, and then convert your im-
age to CMYK by choosing Image > Mode > CMYK Color.
If you want to see the CMYK preview while working in RGB, press Ctrl+Y (Windows) or Com-
mand+Y (Mac OS). This way, you can work in the RGB mode while you see the CMYK preview on
your screen. This is a toggle keyboard shortcut, meaning that if you press Ctrl+Y or Command+Y
again, the preview is turned off. You may not see a difference in the image, depending upon the
range of colors, but the title tab indicates that you are in CMYK preview mode by displaying
/CMYK after the title of the image.
Reading a histogram
Understanding image histograms is probably the single most important concept to becoming familiar with
