I was on a shoot yesterday, i shot somewhere near 60 panoramas. I used to leave the camera in my panohead to shoot the nadir and then take the tripod out in photoshop, but I shot each nadir handheld yesterday hoping that it would cut down my time in post-processing. On 90% of my panoramas there are stitching errors only on the nadir, most are minor, some are major. I just upgraded to autopano giga, and thought that might be the issue, but i tried some of the same panos in autopano pro and got the same exact errors.
My question is, how do you shoot your nadir? Theres probably something obvious that i'm missing. Thanks!
