Footage and sound

More in the reference

Color A warm cinematic grade: the light pulled towards gold, contrast and color lifted a little, skin left believable. LUT A film grade from a LUT file: shadows toward teal, skin and highlights toward orange, the look a colourist hands over as a .cube. Looks The whole archive look in one word: sepia, grain, dust, scratches, projector flicker and a vignette together. Blur Knock the footage back so a title over it stays readable. Denoise Clean the grain a small sensor adds in the dark. Punched in so the grain is actually visible at this size, because at full width it is too fine to see. Glow Make the lights bloom on a city at night.
