I have been wanting to post this for a while.
Many times, specially when there are closeups of different parts in the videos, I lose the sense of scale. It is not exactly clear how small or big what is being shown is.
Sometimes I get an idea when Dave's fingers come into the frame.
Anyhow, I think I would be useful to include in the frame, specially when making emphasis on the size of something, something with known size to be able to compare. Maybe Dave's ruler.
Any thoughts?
