About the Author
I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.
Very nice. I like the atmosphere effect around the Earth. How did you produce that effect?
It's just a matter of combining two blur nodes ( one for the slice effect and another for overall glow [ I used the AlphaOver node ] ) with the original image.
