The principle technique and simple example application of PS Channel drawing

Step one, if we need to pull down the hands of the figure, the first thought is the lasso tool directly strokes. And the use of magic wand tools and lasso tools is not very accurate first, and the time is also a lot of hair, so here we use the channel to pull the map, then you can save a lot of time to observe. As shown in the figure:

Step two, enter the channel first, observe the red, green, blue three channels, found that the red channel is the strongest contrast, the edge is very clear, so use it to complete the pull map, the red channel down to the New button, copy a, must be copied, not directly in the red channel operation. As shown in the figure:

Step three, so into the red copy inside, click on "image-adjust-curve", point that black straw, in the gray black point of the map, you can find in the darker parts of pixels will become pure black, the point of pixels brighter than the place unchanged. As shown in the figure:

Step four, the same way. White habit points and the grey parts of the loving hand, can see, a hand shape appeared, the original Black-and-white gray level has almost become a black River white, the edge is also very obvious, this is the constituency we want, if you do not want to use a straw point, you can also adjust the curve as shown in the picture:

Step five, the rest of the more simple, point blue Picture button, the channel loaded into the selection, back to the level of the panel, hand this layer, the reverse selection, press the DELETE key so that a hands are buckle down. As shown in the figure:

Step six, it seems that the method is more complex, in fact, you may be familiar with the discovery of half a minute can be done. This kind of channel cutout is also suitable for the later image synthesis. Three-dimensional picture map to pick up the packaging of words, but also a part of the photo processing. But this channel is also a certain limitation of the map, only the color contrast is strong, or the contrast is stronger than the image can use the channel to pull the map, compared to the flower of the graph is not good to achieve. The final effect figure is as follows:

The above is the PS channel to pull the principle and simple examples of the use of all the content, of course, on the channel-digging case study in front of a lot of case studies, you can go to learn worry-free search can, hoping to help you improve your Photoshop actual combat skills.
