Curves use a simple principle to allow subtle, natural-looking adjustments to the brightness and colors in your media at different levels of brightness or color intensity. While Curves are definitely one of the more advanced controls, it just takes a couple of features to be explained for you to dive in and begin using them.
- [Instructor] Curves are perhaps…my favorite color adjustment control.…When first looking at them,…they may not seem to do all that much for you,…but they're actually an incredibly flexible and precise tool…for adjusting the appearance of your images.…They work the same way in every application.…Learn them once and you can use them everywhere.…The way I learned how curves work…is by somebody drawing a line…to indicate the brightness of a pixel…coming in and going out from the effect.…You can use curves controls…to adjust individual color channels, too,…but let's just start with the overall luminance.…
What's rarely clear in a curve control…is that it's kind of a graph,…with the horizontal axis…representing the level of the original image,…or let's just speak about an individual pixel,…and the vertical axis…representing the resulting output level…once an adjustment has been made.…You'll notice the default set-up has a line…going neatly from not percent to 100%,…so no changes are made.…I'm saying 100% here rather than a particular level…
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.
