Overview Cameras of the Sony CineAlta series are equipped with the User Gamma function, which enables users to set desired tone curves at will, using the gamma compensation capability. CvpFileEditor is a tool for freely creating and controlling the gamma compensation characteristics of the cameras. Cameras on which gammas created by CvpFileEditor can be used • HDC-900 series (AT Ver. 1.3 or later) • HDC-F950 • HDW-F900 (AT Ver. 2.xx or later) • HDW-F900R • F23 • F35 • HDC1000 series (optional HZC-UG444 required) Gamma Compensation For compensation for smooth contrast characteristics as a successor to knee compensation Knee compensation is a function to compress the contrast for high luminance by a polygonal curve. As the contrast characteristics sharply change at the turn-off point of the polygonal curve, a point may be visible on a subject that has smooth gradation. In addition, skin color of high luminance is prone to coming out yellow. By setting user gamma, smooth gradation can be reproduced without sharp turnoff that may be seen with knee compensation, while maintaining high-luminance contrast. Optimum characterizing according to the dynamic range of each camera The F23/F35 Digital Cinematography Cameras can have a dynamic range of 800% at maximum, enabling contrast reproduction at higher luminance than conventional cameras of 460% dynamic range. The User Gamma function enables creation of the optimum gamma curve according to the dynamic range of each camera. Optimum characterizing for postproduction With a curve set for usual video materials to mainly compress high-luminance contrast, color grading for high luminance is not sufficiently allowed. User gamma setting permits you to decrease total contrast for easy postproduction processes. Image creation by directly adjusting camera outputs If direct outputs from the camera are used without assuming postproduction, user gamma can be used as a function for real-time tone control. Major Functions of CvpFileEditor Management of gamma data and user gamma files You can manage created gamma data with a list. As the data can be grouped as a user gamma file to install in a camera, it is easy to replace gammas in a camera, depending on shooting scenes and conditions. A title and various comments can accompany your gamma data, which can be used as a reminder of the recording condition or tips when editing other gamma data. Strongly enhanced curve editing functions1) Parameter Edit mode is added to automatically create an optimum gamma curve by specifying some major parameters that determine the gamma. You can arbitrarily specify elemental parameters, such as dynamic range, white limit, 18% gray (middle tone), black level, and initial gain. You can also intuitively change these parameters by operating a graphic display with your mouse. Custom Edit mode is also available for more detailed gamma data editing, permitting you to freely edit without parameter setting. Unlimited hyper gamma setting1) As a function for parameter editing, hyper gamma can be selected. Hyper gamma is a gamma curve based on an algorithm unique to Sony. It reproduces natural contrast and colors from middle tone to high luminance on a monitor screen. It features convenient adjustability to record images to be used as-is for video materials or as raw materials to be processed in postproduction. Direct transmission of gamma data via Ethernet1) In addition to the conventional installation method that uses a Memory Stick, created data can be sent in a few seconds to a camera (if it is F23 or F35) via Ethernet for checking the characteristics of the curve on the spot. This may be especially convenient for real-time process of the tone curve according to subjects. Renewal operation displays1) All the graphical windows are newly designed to enable management and editing operations for gamma data, as 3 Overview
