Question

state the procedure for changing brightness,contrast,hue and saturation
​

Answer 1

Answer:

Apply a Hue/Saturation adjustment

Do one of the following:

Click the Hue/Saturation icon in the Adjustments panel.

Choose Layer > New Adjustment Layer > Hue/Saturation. Click OK in the New Layer dialog box.

The two color bars in the dialog box represent the colors in their order on the color wheel. The upper color bar shows the color before the adjustment; the lower bar shows how the adjustment affects all of the hues at full saturation.

Note:

You can also choose Image > Adjustments > Hue/Saturation. But keep in mind that this method makes direct adjustments to the image layer and discards image information.

In the Properties panel, choose from the menu to the right of the On-image adjustment tool :

Choose Master to adjust all colors at once.

Choose one of the other preset color ranges listed for the color you want to adjust. To modify the color range, see Specify the range of colors adjusted using Hue/Saturation.

Choose a Hue/Saturation preset from the Preset menu.

For Hue, enter a value or drag the slider until you are satisfied with the colors.

The values displayed in the box reflect the number of degrees of rotation around the wheel from the original color of the pixel. A positive value indicates clockwise rotation; a negative value, counterclockwise rotation. Values can range from ‑180 to +180.

Note:

You can also select the On-image adjustment tool in the Properties panel, and then Ctrl-click (Windows) or Command-click (Mac OS) a color in the image. Drag left or right in the image to modify the hue value.

For Saturation, enter a value or drag the slider to the right to increase the saturation or to the left to decrease it.

The color shifts away from or toward the center of the color wheel. Values can range from ‑100 (percentage of desaturation, duller colors) to +100 (percentage of saturation increase).

Note:

You can also, select the On-image adjustment tool in the Properties panel, and click a color in the image. Drag left or right in the image to decrease or increase saturation of the color range that includes the pixel you clicked.

For Lightness, enter a value or drag the slider to the right to increase the lightness (add white to a color) or to the left to decrease it (add black to a color). Values can range from ‑100 (percentage of black) to +100 (percentage of white).

Note:

Click the Reset button to undo a Hue/Saturation setting in the Properties panel.

In the Properties panel, choose a color from the menu to the right of the On-image adjustment button .

Four color wheel values (in degrees) appear in the Properties panel. They correspond to the adjustment sliders that appear between the color bars. The two inner vertical sliders define the color range. The two outer triangle sliders show where the adjustments on a color range “fall off” (fall‑off is a feathering or tapering of the adjustments instead of a sharply defined on/off application of the adjustments).

Use either the eyedropper tools or the adjustment sliders to modify the range of colors.

Click or drag in the image with the Eyedropper tool to select a color range. To expand the range, click or drag in the image with the Add To Sample Eyedropper tool . To reduce the range of color, click or drag in the image with the Subtract From Sample Eyedropper tool . While an eyedropper tool is selected, you can also press Shift to add to the range, or Alt (Windows) or Option (Mac OS) to subtract from it.

Drag one of the white triangle sliders to adjust the amount of color fall‑off (feathering of adjustment) without affecting the range.

Drag the area between the triangle and the vertical bar to adjust the range without affecting the amount of fall‑off.

Drag the center area to move the entire adjustment slider (which includes the triangles and vertical bars) to select a different color area.

Drag one of the vertical white bars to adjust the range of the color component. Moving a vertical bar from the center of the adjustment slider and closer to a triangle increases the color range and decreases the fall‑off. Moving a vertical bar closer to the center of the adjustment slider and away from a triangle decreases the color range and increases the fall‑off.

Ctrl-drag (Windows) or Command-drag (Mac OS) the color bar so that a different color is in the center of the bar.
