Hasn't voted | Hmmm... (again) - hard to say. I had (and still have) some of these panos too - the horizont just stays curved, more or less regardless of the stitching program you use. The reasons? Or what to avoid? Low focal length panos for sure since wide angle shots are distorted at their edges where it counts for stitching. You might be able to stitch them all right but a slight tilt of the camera on one shot will fuck up the result.
Also don't point the camera upwards (e.g. panorama of a mountain taken from its base) since the perspective will produce a fisheye effect. You can do away with part of this by using the trapezee crop function of photoshop.
Try playing around with the "focal length" function in Panorama Maker - it might help. Also, sometimes the three points to characterize each stich are very close together (based on maximum contrast, I think), try placing them all over the height of the panorama. If that fails, place one of the points somewhere where it doesn't hurt and try to "unbend" the picture by placing the two pins slightly apart from each other on the respective shots.
Most important - never tilt the camera in between shots - be fast - don't take too much time. Heavy cameras help - my Minolta 7D is so heavy it simply doesn't tilt easily ;-) |
