Telecine Calibration using Grey Card Video Levels
Tomislav Lukičić, Sonja Grgić, Mislav Grgić · International Conference on Systems, Signals and Image Processing · 2006
Projection of filmed grey card from shooting location on telecine calibrated according to TAF (Telecine Analysis Film), needs corrections. Instead of correcting signal, telecine is recalibrated according to the light conditions on shooting location presented by a grey card to project closest possible artistic atmosphere of image from shooting location. After the transfer, TAF is relaced and created video signal levels are compared with the TAF reference video signal levels. Results of measurement are compared and differences are established. Differences appear because of different light conditions, deliberately created to achieve artistic atmosphere of the picture. Established differences are used to monitor and maintain the quality of filmed material.
