Channels are a hidden yet incredible way to make extremely accurate selections for color correction as well as a way of isolating images for background removal. Jason Hoppe will walk through how to make the most of them in a variety of scenarios, including how they can be used in creating high-contrast B&W images quickly and easily. He'll show how for hard to select areas such as hair, channels make it much easier to isolate and remove subjects from a background without using the traditional selection tools. He'll also show how to get a more effective color correction and adjustment workflow by isolating your color channels.
