Color modes are almost like languages. They use different approaches to capture color information. While all color systems seek to accurately record and reproduce color information, there are standards that you'll work to, particularly if you're producing content for broadcast television or the cinema. Traditionally, computer screens use RGB color, televisions use YUV, and printers use CMYK—but what does this really mean? Find out in this video.
- [Instructor] When we think of color,…well, the truth is we tend to not think about it…much at all really.…We see things and interpret what we see…as best we can.…The rods and cones in our eyes…capture light differently.…In this way, our eyes have a color system.…Cameras, computers, and displays do, too.…And different color systems exist…that are used to capture images in cameras,…then another system's used to record the information.…Another system stores it,…yet another system reads it,…and another displays it.…
It's pretty vague and unhelpful, isn't it?…Actually, the systems all work in pretty familiar ways…but with new names.…When capturing color, we have a challenge.…Cameras can't capture all the colors…that appear in the real world.…And when we say color,…I suppose we should give that word a meaning,…which is generally considered to be the colors…our eyes can see.…There are colors outside the visible spectrum.…You've probably heard of ultraviolet…or infrared, for example.…But these aren't particularly meaningful to us as colors…
Get ready to remove the mystery behind terms you've encountered. If you work in a creative profession, this can enhance your command of the tools you use. Learn what a pixel really is, what color channels are, and what audio frequency is. Discover how color channels, bit depth, and video frame rates work. Find out the difference between codecs and file formats, and how compression is involved. By the end of this course, you'll know how to answer common client questions—like, whether a logo should be supplied in vector or bitmap form, and more.
