The blending mode in Photoshop is the difficulty of its understanding, its essence is a special form of choice, is a kind of invisible ant line selection. By blending modes, you can determine which levels of pixels are masked or altered in a determined manner, so understanding the mechanism of the blending mode is important to the user's goal of using PS. The following is an example of how to use the color Dodge mode in PS to extract lines from the image and the resulting reflection.

1. Open the image.

2. The draw line effect generally does not need to retain the color. Use the Go to Color command on the image Adjustment menu, and then copy a layer.

3. Use the reverse command on the image Adjustment menu.

4. The above effect is modified. Double-click the background copy layer, bring up the Layer Style dialog box, split the Black slider of the next layer, and merge the darkest pixels of the background layer into the final image, making the effect more natural.

5. When you change the blending mode of a "background copy" from normal to "color Dodge", the document seems to be empty, but attentive readers will find some black dots on the image.

6. Use the "minimum" filter for the background copy layer with a radius of 1 pixels, that is, this insignificant change created two layers of subtle nuances like plain order, pulling out the edges of the sharp contrast and ignoring the rest of the less intense contrast.

Hint: It should be pointed out that the traditional line-drawing effect of this step using the "Gaussian blur" filter, the effect is not satisfactory.


7. The above effect is modified. Double-click the background copy layer, bring up the Layer Style dialog box, split the Black slider of the next layer, and merge the darkest pixels of the background layer into the final image, making the effect more natural.

8. The final result.

The effect is interesting, but I'm afraid not many friends are willing to bother to think about the mixed mode is what. Paste the dry stripes and the "color dodge" pattern of the schematic, for the friend to refer to it.

If you know how the blending mode is going, you have entered the realm from realm.

In "The choice of art--photoshop CS image processing In-depth analysis", I have quoted an American master of Photoshop, the importance of choice (blending mode is also a special form of choice). This is what the master said: The nature of Photoshop is an art of choice.
