Join Richard Harrington for an in-depth discussion in this video Saving a selection as an alpha channel, part of Photoshop: Selections (2013).
…I've mentioned Alpha channels before.…They really come in handy when you want…to store transparency for use outside of Photoshop.…Maybe it's to add a spot color when you go to the…printing press, or to key a graphic over a live video source.…Or applications like Flash use them for transparency, as does the web.…So there's lots of ways that the Alpha channel comes in handy.…But, let me show you how to store it.…I'm working with the same file from before.…Or you can open up this next version.…I want to add a Drop Shadow here, and I'll just drag that shadow into place a bit.…
