They will depend on your (insufficiently distributed) CPs, and the optimizer tries to make the best of it. You must calibrate the lens with data which are fit for a calibration - 20-30 shots, static scene, indoor, ceiling and wall content, panorama head - these a.b.c and v values you can use for an actual landscape 6+2 take (do make a nadir shot as well). Only reoptimize for v,d,e and NOT for a,b,c with the 6+2 landscape. If you don't have reliable calibration data, it's better to work with a=b=c set to 0 or try to use someone else's data, but you need the stereographic setting. > At least for my outdoor landscape (means: ground , horizon, sky) 360° > panoramas. > I do it all the time, landscapes with the Samyang 8mm 6 around 1 up 1 down, I know it works. with regards KFJ -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
