This is a study, so I have gone with a quick & dirty composite rather than anything more time-consuming.

Total stairs climbed for this study: 2100. Total stairs to reach the CN Tower Main Deck: 1700. Yeah, ow.

Lessons learned from this study: I need to move past a metronome to custom click tracks, it's too hard to keep track without; the slight lean on the upstairs turn is fun; moving up and down rather than across the stairs quantizes the travel distance per step and makes it much more regular; filming stairs from a side angle or a high side angle is surprisingly difficult; and yes we definitely need a high angle.

Minor epiphanies: why not have the performers progress along the staircase, sidewinder-style?

Hmm…it looks like things are taking a while to load. Try again?
