The main thing I wanted to do with this demo was to perform a real 3d-scan with a dancer in motion, which involved flashlight at the right time (Kim handled this through the audio cue)
But also, I felt like my previous demo was not clear enough with the light workflow. By slowing everything down to 1/8 of the regular speed, I felt like it would make it easier to understand what's happening behind the curtains. Things are going in this order:
- constant white LEDs are on (ambient lights)
- trigger signal is requested (from my finger bluetooth presenter... I'm right outside of the framing)
- LEDs turn to rainbow and audio cues start (3 seconds countdown)
- exposure starts on all cameras (1/40s)
- exactly half way during the exposure time, 4 strobes are fired (1/1600s), freezing perfectly the dancer
- constant white LEDs are back on
This is all automated with a single click of a button using Xangle Camera Server. Sweet!
With Kim Henry
