Makin' a Nebula by removing stars in Photoshop, then animating in After Effects

In this tutorial, the first of four of creating nebulas in Adobe After Effects, I start by getting an image of the Horsehead nebula from Nasa's image galleries. I run it through Photoshop to remove the stars and background, using the Select Color Range, spot removal and the background removal tool. Once cleaned, I drop it into After Effects and use CC Particle World to add dust, gases and 3D stars.

Here you'll find a bunch of tutorials for using After Effects (mainly). I have a YouTube channel, called ShiveringCactus (long story - not funny anymore) where I post the videos.
