Cool...no probs stwert.

John, cool mate, yeah we had matchmovers do that for us at Cinesite. Orthographic views are a bit of a lottery though, they always have been as you cant really get stuff side on or front on with a small bit of perspective coming into an image. Unfortunately I dont have PFtrack or know how to use it otherwise I'd do that too

Also to find the focal length, you can actually go to an images 'properties' and usually it will tell you there to

cheers
