Deke Thanks for the reply, yes ive seen these Videos before and whilst i believe the techniques in the video will work for most situations where the camera is locked off, Things tend to get a bit more complicated when the camera plate is moving and there are subjects in the shot,

Logically i assume you'd just tile up the six packs and deal with it that way, But the image dimensions might end up potentially large... 2.mapping the latlong onto a sphere and then projecting images onto the > sphere to patch and fix images. > > Would projecting onto a sphere would result in a lack of parrallax? so im guessing you might need geo of the scene ideally?
