C300: Picture Profile settings featuring canon log help.

[iijohnkeatingii]

Hi guys,

I'm about to begin shooting my next feature with the c300. I had read somewhere that the best way to set the camera to canon log is to go into picture profile, start from a fresh picture profile and turn on canon log from there. In the article I read it mentioned something about avoiding a sharpening mask that kicks in when you use the cinema lock feature. Can someone confirm this for me. Should I just use the Cinema lock to be sure? I appreciate the help as always.

CP CINEMA Locked is a mode Canon has included with the C300 to easily engage Canon Log and prepare the camera's color matrix for optimum post-production results. It allows the cinematographer a simple, no-nonsense pathway to "lock-in" a flat color matrix and Canon Log gamma. This takes the guesswork out of the process when the cinematographer simply wants to set up the camera to be ideal for color correction.

To activate CP CINEMA Locked mode on the C300, press the MENU button and then choose Camera Setup > CP CINEMA Locked > On / Off.

The difference between using CP CINEMA Locked mode versus setting the Custom Picture to C8 (CINEMA) is that once the camera is in the CP CINEMA Locked mode, you won't be able to modify custom picture items such as gamma, knee, color matrix adjustment, etc. All of those settings are effectively "locked out."

While it might seem like you are losing control of how your images are captured when using the CP CINEMA Locked mode, in actual fact you are both simplifying the production process and optimizing the final footage for post.

CINEMA locked is also ideal in multi-camera rental situations. By enabling this mode, the only settings that will need to be matched in camera are the ISO, aperture, shutter angle, bit rate/resolution and frame rate. With these matched, each camera will be capturing the same image and will be much easier to work with in post.

CP CINEMA Locked essentially treats your C300 like a traditional CINEMA film camera where you will meter, set ISO and other capture settings and then let the camera produce the most malleable images possible that can then be "color timed" or graded in post.
