Exposure, Dynamic Range and Image Pipelines
Exposing for latitude and building the pipeline from scene to screen: stops and middle grey, meters, waveforms and false colour, dynamic range and latitude, log and raw encoding, exposure strategies, LUTs and the ASC CDL, colour management, ACES, HDR and SDR delivery, and the DIT and on-set data pipeline.

What you'll learn
- Explain exposure in a digital cinema workflow using stops, middle grey, T-stops, ND and scene-referred concepts
- Measure light with incident, reflected and spot meters and calculate exposure, distance falloff and lighting ratios
- Read waveforms, RGB parades, histograms and vectorscopes to judge exposure and colour objectively
- Use false colour, zebras and other exposure assists, knowing where each measures in the monitoring chain
- Analyse scene, camera and display dynamic range and manage latitude, highlight roll-off and the noise floor
- Explain log encoding, manufacturer log curves, bit depth, raw recording and codec choices
- Apply exposure strategies for skin, day exteriors, windows, night scenes, high contrast and visual effects
- Create and manage technical and creative LUTs, show looks and ASC CDL adjustments
- Apply colour management with primaries, white points, transfer functions and scene-referred working spaces
- Design and troubleshoot ACES pipelines, including input and output transforms, ACES 2.0 and AMF
- Plan HDR and SDR mastering and delivery using PQ, HLG, HDR10 and Dolby Vision
- Organize on-set monitoring, data management, dailies and a documented image pipeline with the DIT
