Adobe photoshop cs2 사용자 설명서

ADOBE PHOTOSHOP CS2 

The Variations command lets you adjust the color balance, contrast, and saturation of an image by showing you 
thumbnails of alternatives. 

This command is most useful for average-key images that don’t require precise color adjustments. It does not work 
on indexed-color images or 16-bit-per-channel images (Photoshop). 

Choose Image > Adjustments > Variations. 

The two thumbnails at the top of the dialog box show the original selection (Original) and the selection with its 
currently selected adjustments (Current Pick). When you first open the dialog box, these two images are the same. 
As you make adjustments, the Current Pick image changes to reflect your choices. 

Select the Show Clipping option if you want to display a preview of areas in the image that will be clipped— 

converted to pure white or pure black—by the adjustment. Clipping can result in undesirable color shifts, as distinct 
colors in the original image are mapped to the same color. Clipping does not occur when you adjust midtones. 

Select what to adjust in the image: 

Adjusts the dark, middle, or light areas. 

Changes the degree of hue in the image. If you exceed the maximum saturation for a color, it may be 

clipped. 

Drag the Fine/Coarse slider to determine the amount of each adjustment. Moving the slider one tick mark doubles 

the adjustment amount. 

Adjust the color and brightness: 

To add a color to the image, click the appropriate color thumbnail. 

To subtract a color, click the thumbnail for its opposite color. For example, to subtract cyan, click the More Red 
thumbnail. See “Using the color wheel” on page 248. 

To adjust brightness, click a thumbnail on the right side of the dialog box. 

The effects of clicking the thumbnails are cumulative. For example, clicking the More Red thumbnail twice applies 
the adjustment twice. Each time you click a thumbnail, the other thumbnails change. The three Current Pick thumb­
nails always reflect the current choices. 

You can also save the settings you make in the Variations dialog box for reuse on other images. For more information 
on saving and loading settings, see “To save and reapply settings in a dialog box” on page 282. 

The Equalize command redistributes the brightness values of the pixels in an image so that they more evenly 
represent the entire range of brightness levels. Equalize remaps pixel values in the composite image so that the 
brightest value represents white, the darkest value represents black, and intermediate values are evenly distributed 
throughout the grayscale.
