I’ve pick 600 frames (1 frame every 3 frames), tonal adjusted and converted those frames into grayscale, inverted to negative images and made that into a single contact sheet file.
Next step is printed that contact sheet into prepress/offset film, cut into every single frame and printed by van dyke technique.

After printing process, i photographed all prints one by one, and assembled into 60 seconds video (excluding title & credit). Every 1 second video made from 10 frames (prints) and played in 30 fps.
