Panavision has released a series of technical tutorials covering HD camera systems and related workflow. Each tutorial is available in 480p, 720p and 1080p for downloading.

Part 1 discusses the following topics:  A short history of CCD/CMOS development, Sub-sampling and Super-sampling, HD lens and camera design strategies, Photosites - the tradeoff between resolution, dynamic range, and noise, Digital output signals from cameras, UHDTV, 2K and 4K cameras, and DCI Standards for 2K and 4K.

Part 2 discusses the following topics:  The Nyquist Theorem, linking optical and digital sampling, The implications of Fill factor and optical low pass filtering, The Nyquist boundaries of of motion pictures, and Limiting resolution.

Part 3 discusses the following topics:  Introduction to MTF, Introduction to an individual element’s contribution to final MTF, Transferring contrast, Cascading MTFs, Introduction to Otto Schade, Perceived picture sharpness and MTF, Edge Sharpness, image textures, and resolving power.

Part 4 discusses the following topics:  Pixels are not resolution, Practical measurements of MTF, Introduction to sinusoidal MTF charts, The Panavision sinusoidal MTF Chart, MTF benches for measuring lenses, Cascaded MTF of a DI, Sensor MTF response, Depth of Field, MTF measurements of real world lenses.

Part 5 discusses the following topics:  Line pairs per Millimeter, Differences between HDTV and SDTV lens standards, a demonstration of the MTF-Aliasing dilemma using three chip cameras, Loading the imager MTF into the digital container.

Part 6 discusses the following topics:  The resolution metric for a Bayer pattern sensor, Diagonal sampling Bayer pattern sensors, Optical lowpass filter options for single Bayer pattern sensors.

Part 7 discusses the following topics:  Spectral response, Camera color balance: Daylight v. Tungsten, Digital Intermediate MTF comparison between Genesis and 5218, Bayer vs. RGB striped sensors.
