Understanding the EOS C300's Canon Log Gamma
|
People unfamiliar with log may tend to expose their images incorrectly if striving to create an image that looks correct to the eye. To prevent this common problem, Canon has included a new View Assist feature, which allows you to access an on-screen preview of how the image might look once graded in post. By turning on View Assist, the LCD and viewfinder of the C300 shows an estimated "correct" image while still recording a truly flat log picture to the CF card.

The discussions in the White Paper (Deep Dive Part 1 ) centered about the all -important linear representation of the camera video. Now that video must be further “prepped” in a manner that can help ensure that the extensive dynamic range created by the imaging system will be fully protected while being recorded – and also as it is transported over industry standardized interfaces. This is the primary role of the camera’s Optoelectronic Transfer Function (OETF).

At ISO 800 the exposure latitude is 6.3-Stops over gray and 8.7-Stops below gray – and this is termed the Base ISO. Increasing ISO levels above this Base level is implemented by an analog gain control within the image sensor itself and this helps maintain a consistent disposition of exposure about the gray reference all the way up to maximum ISO 102,400.

Many requested the capability of showing the waveform monitor and principal camera settings (presently shown only on the 4-inch LCD monitor of the C300) on an external on-set reference monitor as well as in the camera monitor. In the C300 Mark II the capability has been added to send the WFM and certain camera assist information viatheMON3GSDIinterface and HDMI interface.
