The principle of tutorial method of PS Channel drawing

We talk about the principle of channel drawing;

This method is often referred to by the so-called master is actually very simple to provide a thinking channel is to use the channel to save the color of such a feature so that the color calculation to get the constituency so to learn the channel to pull the map must learn the channel.

The translation of this channel I feel a little bad, but I also can not find a more secure translation methods before I said what is called RGB, what is called Cmyk,rgb is composed of three colors are red and green blue below we use RGB, CMYK can be analogy.

1, the stronger the light, the brighter it will be. The weaker the light, the darker it becomes.

2, three different kinds of light and then mixed together, forming a colorful pattern.

3, the channel is used to save the brightness information of three colors respectively.

I made such a picture: Three kinds of high purity color you can see the thumbnails on the left side of the red channel is white on the left is very bright on the middle and right are black expression completely no red to participate in other analogies

To analyze a picture of red tune

Then look at the channel's thumbnail red channel obviously to light some of this is the image of the red reason people can now look at the channel to know the approximate color of this layer?

Now we select the red channel and then "image"-"adjust"----"brightness/contrast" to bring down the brightness

Again select the RGB mixed channel you will find that because of the weakening of red brightness, the red of the original image is reduced. No, it was so red before you looked at the adjusted channel thumbnail categories:
