I'm shooting a ton of test plates right now to practice tracking/matchmoving and comping to. I'm shooting them on a 600d and wondered if anyone can enlighten me as to how/if the crop factor (1.6?) affects the focal length of the lens?
For example, when I'm setting up the CameraTracker in Nuke, or editing the prefs in PFTrack, I've been putting the focal length of my Canon 50mm lens down as exactly that, 50mm. But am I right in assuming that I should be taking into account the crop factor of my camera in order to get the correct focal length?
If so, would I simply divide the focal length by 1.6? Giving my 50mm lens a focal length of 31.25mm?
Any tips or advice would be amazing.
Huge thanks in advance.
