PS Palette Tips

This tutorial is a pure theory, pure basic knowledge of the tutorial, personally read that the tutorial is still very good to write, so forward, but also with some pictures, hope that the triple friends like this tutorial oh, color matching techniques in Photoshop (PS) in several ways can affect color, including:

1. Curve in the curve of the window can be different colors of RGB adjust the shape of the curve, change the picture color relationship

2. Color balance in the color Balance window can be in the green-red, magenta-green, yellow-blue between the pull color relationship

3. Hue/Saturation in this window can change the hue, saturation, lightness three number

There are 200 ways to influence color in PS

The following we introduce the color method we should be flexible master.

1. Color balance is the simplest; the only thing to be aware of is that this feature can be used to adjust colors for highlighted, medium-bright, and low-light three different parts.

2. Hue/saturation is much more complex. First, it not only allows the color wheel to adjust all hue and saturation at the same time, but also for different six major colors to adjust the hue and saturation, the following section of the color phase wheel, the above represents the adjustment before hue, the following indicates the adjustment of hue; second, it can be used with a straw or a suction tube to specify the exact hue to adjust, Further further, the scope and mode of sampling can be specified; third, if the image itself is not a problem, it can be simple through the ash straw to achieve a gray balance; four, its adjustment scheme can be stored for re-use; five, it can color the black and white image (but the effect is not ideal, because the coloring mechanism here is independent of the gray scale, And color is something that is closely related to gray level, at least in psychology. Lightness indicator, unless entered in lab mode, this metric is rarely used.

3. Curve, curve can almost completely replace all kinds of color adjustment means, use up more handy, but, seriously say curve, probably need 150k.

1.

Input and output values are equal. In other words, people have not had time to do anything to the image.

2. In addition to the darkest point, evenly brighten the whole picture. To be precise, the point a of the input color order 225 is the dividing point, the point is the largest, and all the other points, the farther away from point A, the smaller the brightening range. Even so, the highlighted part of the image-the point where all the input levels are greater than 225-has actually been illuminated to the fullest extent. By this figure, it is not difficult to make a curve with the brightest light of the outer-pressure dark whole picture.

3. In addition to the brightest, darkest point, in order to highlight the middle brightness of the whole picture. Please note that this is not an arc. Arcs are part of a circle, but here, no matter what the circle is, it is impossible to match this curve. It looks like this should be a cycloid, the so-called "steepest descent line" in dynamics. Compare it with the actual arc shadow below, and obviously the ends of the curve are asymmetrical. From this figure, it is not difficult to make the curve of the whole graph under the gray-scale characteristics of the image (the following direct relative curve form is no longer specifically described).

4. Uniform pressure of the entire picture, the brightest part of the maximum dimming, the following this range is gradually reduced to the darkest point is equal to zero (because there is no more dark, can only be equal to zero).

5. There is no differential neutral ash in the whole picture (neutral ash is important in image superposition mode and image Gray balance theory).

6. Reverse phase of the whole picture.

7. The extremely dark point unchanged, the extremely bright spot presses into the extremely dark point, but puts the middle part evenly to raise bright. This type of curve is rarely used in photo adjustments.

8. Slightly highlight the bright part, at the same time resulting in the dark part of the compensatory pressure of dark.

9. Slightly highlight the middle part, at the same time both in the light and the dark part of the compensatory pressure of darkness.

10. Add the locking point, to avoid some of the compensatory pressure dark.

11. With point A (level 192) as the boundary, press the dark side of all parts, and highlight all parts of the left.

12. Three peak adjustment. This curve is often used when doing metal effects.

13. mixed with manual curves.

14. Smooth Manual curve.

15. After the Curve dialog box, press ALT, the "Auto" key becomes the "Options" key, click the option key, you can specify the automatic range. [Press: Automatic curve, equivalent to automatic color order. The problem is deeper, not to mention.

16. Impossible curve (because it is not possible to have different output values for an input value).

The shape of the curve can not be exhaustive, here can only be cited as an example. Antiphon extrapolate can also.

Three straws, all of them are point-drawing straws. Black straw point map, brightness in the click of all parts below into black, white, gray, specify neutral ash.

A curve scheme that can be saved as. ACV suffix of the file, when needed "load" can be.

Adjusting the level of the first adjustment of the body

1. Drag the background of the layer palette to the new layer in the lower right corner (the original image can be lossless)

2; Click the black and white circle at the bottom of the Layer palette click on the pop-up menu to select the pre-range in the Hierarchy dialog box

3; Press the ALT key while dragging the right black triangle to the left until the image appears in white pixels

4; Press the ALT key to drag the left black triangle to the right to appear black pixel stop

5. Drag the middle gray triangle brightness (midtones) satisfied after OK

Re-adjusting saturation degree

Click Hue saturation to adjust color and saturation in the menu to obtain satisfactory results
