For example, in the case of the C300 camera, such a video specification is as follows: With scene illumination of 2000 Lux at 3200 degrees Kelvin, a reference white of 89.9% reflectance, camera Master Gain set to 0 dB, Gamma and Detail enhancement switched off, the lens T-stop setting to produce 100 IRE of Luma video level on a waveform monitor is T-10, under which conditions the camera Lumasignal to noise ratio is 54dB.

EOS c500 & C300

The traditional broadcast video specification for lens-camera sensitivity is measured bythelens aperture setting in F-stop required to achieve 100 IRE units of Luma when the system is imaging a reference white chart having 89.9% reflectance under 2000 Lux of 3200 degree Kelvin illumination (with Camera Master Gain set to 0 dB, Gamma switched off, and all image enhancement switch off). Under those conditions, the amount of electronic noise in the image is another important issue closely allied with this sensitivity specification because of its bearing on dynamic range.

COMMON STEPS TO PREP THE EOS C300 FOR SHOOTING

Shutter Control: Shutter timing on the EOS C300 can be set to any of the following methods: • Shutter Angle (range 360°~11.25°) • Shutter Speed (range 1⁄24 ~ 1⁄ 2000 second, at 23.98 fps; slow speed varies depending on fps) • Slow Shutter (range 1⁄3 ~ 1⁄30 sec.
