Creating, Moving, and Deleting Color Samplers

Creating color samplers is very easy. All you need to do is select the Color Sampler tool and click in the image. You can embed up to four color samplers per document. However, deleting single samplers is not so obvious and, as usual, there are several ways of going about it:

■ Make sure that the Color Sampler tool is active, grab the color sampler that you want to delete, and drag it out of the document window.

■ A bit more elegant method is to right-click (Windows), Ctrl-click (Mac OS) the color sampler and then select Delete from the contextual menu.

■ If the Color Sampler tool is not active, press Ctrl (Windows), ^ (Mac OS) and then drag the sampler out of the document window.

■ If the Color Sampler tool is active, you can hold down Alt (Windows), Opt (Mac OS), hover over the sampler, and click when the icon turns to a scissors. If a tool other than the Color Sampler is active, add the Shift key to the above keyboard shortcut.

To delete more than one sampler, select the Color Sampler tool and then click the Clear button on the options bar.

So, is that all there is to creating, moving, and deleting color samplers? Well, not quite. Believe it or not, you can place color samplers without the Color Sampler tool! Photoshop just seems to know when you may need them. For example, when you use some of the adjustment commands, such as Curves, Levels, Hue/Saturation, Selective Color, and Color Balance, the active tool changes to the Eyedropper, which in turn allows you to temporarily access the Color Sampler tool by pressing the Shift key. When you step out of the active dialog box and into the document window, just hold down the modifier key and click to place a color sampler (Figure 2-31).

When you have an adjustment command's modal dialog box open, such as Curves or Levels, you can still move and delete the color samplers. To delete, press Alt+Shift (Windows), Opt+Shift (Mac OS), hover over the color sampler, and click when the icon changes to a scissors. To move a color sampler, press the Shift key by itself. One other useful shortcut is the right-click (Windows), Ctrl-click (Mac OS). You can use it on a color sampler to change the sample size between Point Sample, 3 by 3 Average, or 5 by 5 Average.
