Following the scene plan that we already had in place, we stared discussing how each scene would be best filmed. We started by drawing little, undetailed sketches on post-it notes. This allowed us to move them around and easily scrape the unnecessary ones. The process of re-drawing and reorganizing took up the entire session. After we planned our main scenes and we all agreed with the order each one should take place, we started adding detail, such as facial expressions of fear or sadness, wind, sounds etc.
This allowed us to envision the final project better and to make sure there were no misunderstandings in the way everyone perceived it.
Later the storyboard was put into a digital form to ease the access.
