I've been following Ed's example, but Martin asked that I start a thread so that we can all standardize what we're doing with our cameras.

In my big, master project where I have links to all of my chors, I have a link to TheCamera.cam in my root _1_02 folder. I've been going through the chors and swapping out their misc cameras for TheCamera. TheCamera is set with the right dimensions and render settings. All I change in the chor shortcut is the name of the file I'm rendering to and the length of the chor.

Ed: Is that what you are doing?

Others: How are you doing things like this?

Yes. Basically, anything that you want to be uniform across all of your chos (like output size), make that change in the actual camera's properties (in Objects). To make scene-specific changes (like file name, frame range, focal length, etc.), make your change in the camera's shortcut's properties (in the Cho).

For the most part, the camera's "Render options" are set in the camera and the "Output options" are set in the shortcut. Exceptions are depth of field, motion blur, etc. I haven't saved the camera externally yet and don't know if I ever will. I haven't found a compelling reason to do so.
