There's been quite a bit of debate about Blitter's 'Mundane Girl' renders - are they real? Did he photoshop real pictures onto a CG background? I guess this video concludes the argument.
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.
