1, please read the following text, and then look at the Tutorial! Channel Buckle Principle: Channels are: Color channel, alpha channel, and spot color channel. Where the alpha channel is used to store the selection, the alpha channel is a black to white middle 8-bit grayscale that will be selected for saving. Instead, we can use the Black-and-white contrast in the alpha channel to make the selections we need. (White is the selection of the alpha channel) levels can be adjusted to adjust the image of the darkened, the middle harmonic high light intensity level, to correct the image tonal range and color balance. We can increase the black-and-white contrast of the image by color order, and use this to determine the selection range 1.
