FXPHD - DCT301 Camera Tech and Colour Science
10 ClassesProject Files Included MP4
Camera operators and assistants, colourists, visual effects supervisors and artists, and others are making the transition to digital acquisition. Digital imaging technicians (DITs), digital intermediate engineers, and technicians are also centrally involved. Leading the course is the incredibly knowledgeable Charles Poynton, who will discuss color and digital cinema acquisition in a manner thats accessible to cinematographers, colourists, and related craftspeople.
How many stops of exposure latitude does a digital camera offer? What exposure index should be used? What is thefilm look and where should it be imposed? Why does noise arise, and what can be done to minimize it? Should I record and process log or linear? Is there one kind of log and one kind of linear, or are those terms ambiguous? Is it valuable to have an on-set display? Where do the LUTs go, and who should determine their content? Under what conditions is on-set colour grading useful?
Poyton will discuss logarithmic coding, camera sensitivity and ISO/EI ratings. He will describe the zone system, and discuss what aspects of that system are valuable in connection with digital acquisition. In addition, the course will cover the tone scale and colour modifications that impart the film look, and the roles of camera controls (gamma, knee, slope) and 1D and 3D lookup tables in achieving these modifications.
This course will be suitable for people involved with:
Cinematographers, assistant cinematographers, and colourists
HD engineers and Digital Imaging Technicians (DITs)
Post-production and visual effects supervisors, and post/VFX engineers
Digital cinema, digital video, and CGI/VFX software developers
