photoshop's" Gradient Map" command can be equal to the scope of the image gray-scale maps to the specified gradient fill color, such as the designated two-color gradient fills, shadows in the image is mapped to an endpoint of a gradient fill color, high light is mapped to another endpoint color, while the middle tone is mapped to the gradient between the two endpoints colors.
Now let's take a look at how to define a specific gradient map, first of all to open a map.

implementation of the" image> adjustment> Gradient Map" command or the" layers> New Adjustment layer> Gradient Map" command, that will pop up," Gradient Map" dialog box.

Click The gradient of the dialog box, either can edit the Gradient pop-up dialog box.

A01 : The Gradient Map of the default, click the gradient box with the mouse, you can apply the gradient map, you can also preset the top right of the small triangle and loading, storage button to read and save a custom preset
A02: There are two types of gradient, a" real end" and the other a" motley" in the figure above we see is real at the end of the gradient," Miscellaneous color" of the gradient is randomly generated, are generally used for production of more dazzling special effects, where not included in the recommendations here.
A03: smoothness of the set and then photoshop the Help file, there is no explanation in the personal use of the process, just think smoothness settings can be appropriately enhanced images of the contrast. In some very minor changes, you can try to adjust.
A04: non-transparency of the color used to set the opacity gradient, when the 100% opacity, the opacity of the color under the color of solid color; when not transparency 0%, the opacity of the color under the color of a transparent color; when the 50% opacity, the opacity of the color under the color of translucent colors, and so on. Opacity, color can influence the slide, set the opacity of the gradient points can also be two non-transparency of the color between the click, you can add a new opaque color punctuation.
A05: the left-color Punctuation
A06: the right color Punctuation
gradient editor of the most The main is to control the A05 and A06, well, let's take a look at how to control the color punctuation.

Single blow color punctuation, color it was selected, and figure above B01 is selected, B02 is not selected.
single-color punctuation is selected, they can edit the color, click the color block under the figure could be the pop-up Color Picker dialog box, choose the color.

will be around both ends of the color punctuation are redefining the color.

gradient punctuation between the two colors will have a" color mid-point" , see figure below shows, is used to control the amount of the size of the gradient, and can drag the" color mid-point" close to the two-color punctuation, or" location" , type numerical control.

click is to control the" color midpoint" position, after the results of the different gradient maps.

At this point, we have understanding of the various parameters of gradient maps to use, and now we do a gradient map. Click the preset inside the" black, white" gradient, the gradient map adjustment to the black to white from the basic stage. Of course, this is also a way to transfer the image gray level effectiveness.

us In the middle of the two color points, click of the mouse, you can then add a color point, the color point location and how to select the color is critical. To learn more about how to choose the location and color point color point color, let us first look at the basis of color.
color contains three elements, namely, hue, brightness, saturation. Hue (Hue) is the main color of the wavelength of the color of the physical and psychological characteristics, popular terms, red, orange, yellow, green, green, blue, purple is the color appearance of the property that is the hue. Commonly referred to as warm is also a cool hue to reconcile the scope; brightness (Brightness) is the color of the relative brightness level; saturation (Saturation) is the color of purity, usually referred to as brightness.
and the gradient map is equal to the scope of the image gray-scale maps to the specified gradient fill color, the gray matter of fact here that the scope of mapping means to map the different brightness.
color brightness range from 0 to 100, while the gradient is from 0 to 100, from which we can be graded on a point does not change the color brightness, hue and saturation change then, you can get a complete grayscale gradient maps.
Here, the choice of colors and color location of the point, pay attention to the value of red box, as far as possible equal to

results as shown.
