Physical Camera Types

[toby™]

Hi there

There are 3 different types provided by Chaosgroup for our PhysicalCamera, 'Still', 'Movie' and 'Film'. What are the advantages or even disadvantages of those different types, in therms of creating and rendering film projects?

Type - determines the type of the camera. This mostly has an effect on the motion blur effect produced by the camera:

Still camera - simulates a still photo camera with a regular shutter.

Cinematic camera - simulates a motion-picture camera with a circular shutter.

Video camera - simulates a shutter-less video camera with a CCD matrix.

What is the "effect" like? What are your experiences when dealing with film projects. Should I need to render DOF and/or MotionBlur directly into the footage?

best regards,

No one actually?

The effect is mostly on motion blur and how the camera exposure is specified. With the still camera, you have the shutter speed, with the movie camera you have the shutter angle, and with the video camera you have the latency parameter.

Hi Vlado!

That's what I've known already -- I want to know more about the advantages or disadvantages between each of the 3 camera types. Would it be reasonable to use a 'Still Cam' instead of a 'Movie Cam' to gain better control on the DOF effect?

I've wondered about this, too. Are there any example images/animations that demonstrate the differences/different uses?
Thanks

There are no other differences...

Best regards,

Hi,
With regard to the advantages of the different camera types, each camera type is simulating a real world camera type. The still camera for eg. could simulating a DSLR like a Canon 5d or Nikon whatever. If you are doing a photo-real still it makes sense to use this camera to simulate the correct f-stop(which affects depth of field) and shutter speed(which affects the motion blur). The Movie camera is simulating a Cinema style camera. The only real difference is the movie cam has shutter angle instead of shutter speed. look at this http://en.wikipedia.org/wiki/Shutter_angle
I never use the video cam and I don't know what latency is but I know it affects motion blur.
Sorry, this is a lazy response.

I always use the Still camera for stills and animation because I don't see any difference in the output, however there must be some value in the different rigs otherwise why would they be there.
