BRIGHTNESS	Adjusts the level of brightness of the entire image.
	NOTE: Refer to “Change Brightness” earlier in this chapter for
	additional information on this option.
CANCEL	Leaves the KODAK Driver and returns you to Adobe
	Photoshop without returning any scan data. (Pressing ESC or
	holding down the Command (Z) key, pressing the period
	key, then releasing both keys produces the same result.)
CLICK NOW	See CLICK WHITE.
CLICK WHITE	Automatically adjusts color balance via a user-selected gray
	or white portion of the image.
	Click the CLICK WHITE button, then click a neutral spot in the
	image known to be gray or white. (Do not click on a dark
	shadow or a bright highlight or overexposed area.) This
	action automatically displays changes in the image window
	and repositions the color sliders in the BALANCE area of the
	window.
	NOTES: Once clicked, the name of the CLICK WHITE button changes
	to CLICK NOW, a prompt indicating that you should click the image.
	You can also cancel without clicking the image by clicking the
	CLICK NOW button.
	The BRIGHTNESS slider may move; however, CLICK WHITE does not
	optimize on brightness, and you may still need to adjust brightness
	as described earlier in this chapter in “Change Brightness.”
CONTRAST	Adjusts the level of contrast among the elements of the
	image.
	NOTES: A contrast adjustment is a gamma adjustment.
	Refer to “Change Contrast” earlier in this chapter for additional
	information on this option.
Crop	Selects a portion of the image you want to scan. To crop,
	drag the cursor around the portion of the image you wish to
