I home built my own pano head. Using a Sony A65 I can spin around and take my shots. I take 8 shots plus one sky. Sometimes everything works great. The camera has a built in horizon leveler which I use as I am spinning. I am on uneven ground with sand so it isn't the easiest way to shoot a 360 X 180 spherical pano. The images are off on the render. One image is higher than the other and so forth. What methods are there to correct these images to line up correctly? I sincerely appreciate anyone's help. I tried auto horizon and so forth but think what I need to do is manually align images.
