Makin’ an animated Nebula with Adobe Photoshop

In this tutorial, the first of three 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 background removal tools. Once cleaned, I drop it into After Effects and use CC Particle World to add dust, gases and 3D stars. Image credit: Nasa

Expression used:

if (time < thisComp.frameDuration) {

    effect(“Stars Amount”)(“Slider”)*40

} else {
