Join Richard Harrington for an in-depth discussion in this video Using selections to create masks, part of Photoshop: Selections (2013).
…Adding transparency to image files is often important for many users.…For example, maybe you're building a multi-media…presentation using an application like Keynote or PowerPoint.…And you want to place a photo over a background.…Or perhaps you're authoring a web page and…you need transparency within a Ping 24 file.…Or, maybe it's a video edit and you…want to place an image above on a higher track.…There are lots of uses from transparency,…from video to multimedia, to print, and…they all really start with an alpha channel.…
But before the alpha channel, you need an actual selection.…Let me show you.…You'll see on the left, we have…our flamingo layered over its original background.…On the right, I've already extracted the bird…from the background and have stored a embedded…alpha channel that can then be exported with the bird to make it a bit easier.…Let me show you how that was made. And essentially, a selection was made.…I've already saved this selection as an initial alpha channel.…Let me Cmd or Ctrl + click on it to load it as a selection.…
