Re: [Slightly OT] Filmback tables

["Marc Bourbonnais" <marc(at)hybride.com>]

I see some of the values are projector gates, not camera gates.

 

For instance 35mm full is 24.89mm x 14.93mm (0.98"x0.588") for the camera, and usually 24.00mm x 18.237 at the projection only. Projector gates have an extra crop, and you'll want to work with the camera aperture.

 

And to be picky, 35mm Academy should be 21.94mm x 16.00mm (0.864"x0.630") for the correct 1.371 ratio. Not much of a diffrence, but will give a slight error with lens conversion.

Perspective will match according to lens focale used in real world.
Take care of the lens distortion ( who bend perspective line )

Sorry for the OT, but we are doing a previz and the DOP is asking about wether their stuff will match ours, as they have had problems before!  Anyone know of any sites on the net where you can get the size information for different filmbacks and cameras, there used to be gregssandbox, but that seems to have dissapeared!

 

Thanks

 

Sandy
