Camera and Lens variables

The Camera and Lens variables are the photometric analog of the geometric lens correction model, hugin assumes that all input photos with the same lens number have identical values unless they are unlinked in the hugin Camera and Lens tab.

Vignettting

Vignetting is dependent mainly on your lens and the aperture. Usually the centre of the image is brighter with a falloff towards the edges, hugin can calculate this falloff curve as part of the photometric optimisation process or you can enter it manually in the hugin Camera and Lens tab as the three numbers shown here.

Vignetting Centre

The centre of vignetting is rarely the exact centre of the photo, hugin can optimise this position or you can enter it manually in the hugin Camera and Lens tab. The scale is in pixels, with 0,0 indicating the centre of the photo (TODO is this relative to the d & e parameters?)
