Join Bert Monroy for an in-depth discussion in this video Explaining alpha channels, part of Bert Monroy: Dreamscapes Volume 1.
Throughout the series, I use alpha channels quite a bit.…I want to go in here and explain to you what exactly an Alpha Channel is.…First, what are the Channels?…Well, right here, we are going to see this, and we have the Red Channel, it shows you…the red components of that image, the greens, and the blues.…Now, we are seeing them in black and white, we can see them in color, but it is important…to see them in black and white because there are certain different gradiations of a particular tone.…You see that, it is blue.…
Now, that particular pixel right here, we are going to go in there and select that…little tiny pixel right there.…That little composite pixel is a certain value of the red.…There is no green in it, there is the red, the red and blue, there was no green.…But the result is that green right there.…So now, each one of these channels is an 8 bit channel, which has 256 colors.…So, there are 256 variations for that 1 pixel that we are seeing right there.…
The number of value for the red, and the green, and the blue mix will give you that particular color.…
