This video provides a look at how color images are made up of color channels, and how you can use this knowledge to your advantage.
- [Voiceover] In this movie,…I'm going to talk about color channels.…And we have three versions of this image, the RGB,…the CMYK, and the lab color.…Starting with the RGB, and if I come to the channels panel,…we see that it has three color channels: red, green, blue.…The CMYK version has four: cyan, magenta, yellow, and black.…The lab or L-A-B color has three:…lightness, A, and B.…By contrast, grayscale images, bitmap images,…duotone images, and indexed color images,…all have a single channel.…
A duotone is an interesting case in point.…Even though it allows us to print…in more than one ink color,…there is still only one color chanel.…The color channels store information…about the color of each pixel in the image.…I'm going to come to my eyedropper tool…to lay down a sample point.…I'm going to hold down the Shift key, and click,…and then we see that sample point right there.…And it's telling me,…this particular pixel that I have sampled,…is level 208 red,…level 107 green,…and level 141 blue.…
If I move that around…
