3-11-2 Using the Hyper Gamma

Hyper Gamma enables the wide dynamic range of the CCD sensors to be reproduced in smooth contrast without using the knee function.

You can easily adjust whether to widely reproduce high contrast or to brightly reproduce the luminance of the intermediate tones by selecting an appropriate curve. Settings assuming usage of postproduction devices having a white limit of 100% are also provided.

1 Select HYPER on the first line of TABLE on the <GAMMA> page, and select the hyper gamma table most suitable to the shooting conditions and purpose.

These curves are equivalent to those built into the HDW-F900R HD Camcorder.

3-11-3 Using the S-LOG

When SPECIAL is selected on the first line of TABLE on the <GAMMA> page, the second line indicates S-LOG (Sony Log).

Sony Log (S-LOG in subsequent texts) is a gamma which assumes use in the DI workflow (capturing filmed negative images and creating a digital master through digital processing for screening) in cinema production.

S-LOG enables you to monitor the latitude close to negative film and perform the timing (color correction) with a Sony digital cinema camera, achieving “Digital Negative” that is the optimum negative film work flow for digital processing.

With this “Digital Negative” you can have the conventional shooting style, using ISO sensitivity, luminometer and the wide latitude of negative film, enabling smooth transition from film production to digital cinema production.

Detailed information of S-LOG is described in the “SONY- LOG Whitepaper.”For the “SONY-LOG Whitepaper,” consult your local Sony representative.

3-11-4 Using the User Gamma

You can also create a desired gamma table, using a personal computer on which software CvpFileEditor™1) has been installed and load the table into the camera via a “Memory Stick.”

When a user gamma table is selected, control of gamma (LEVEL or ON/OFF) may become disabled, depending on data of the table. This is because the gamma and knee are compulsorily fixed when creating the gamma curve. User gamma curves are initialized with S-LOG at the factory. (The characteristic data of S-LOG can be output in files, using the CvpFileEditor.)

To select the user gamma1 To use the gamma table you have created, load it into the camera.

Load the gamma table data via a “Memory Stick” using the <USER GAMMA> page of the FILE menu in Custom mode.
