Hello, I am a student at the University of Gävle, Sweden. I am writing a paper about chroma keying and compositing and I would appreciate if you would like to take 10 minutes to answer eight questions in total regarding softwares for chroma keying and compositing.
The survey starts with seven questions regarding your relation to different softwares. At the end of the survey you will be asked to study two images, that has been composited with either Adobe After Effects (commercial) or Blender (free), to guess which one is which.
