    Posting a photo would help but if you're saying what I think you're saying then I'll say this; Using manual mode and keeping the same aperture and shutter speed for each photo is one of my keys to pano success. If you allow the settings to change between shots you will definitely notice, and not in a good way. This does lead, quite often, to areas of imperfect exposure, but they are much more easily corrected in post than the drastic differences that show up between frames with varying apertures. Good luck.

    What version of Photoshop?

    What focal length lens were the images shot with?

    Were the frames shot in Manual Mode with AWB turned off, and with Manual focus?????

    Did you use a polarizing filter, perhaps??

    Pretty much have the camera in neutral .. manual mode with the AWB in the off position .. don't use a polarizer .. little reluctant to shoot in manual focus don't want an out of focus panel .. have CR 4 .. thanks don

    Manual Mode, non AWB, no polarizer is a good start.

    If you are shooting objects at distances that are not within DOF at f8 or smaller, and you are refocusing, that will cause some issues I suspect.

    You are rotating your camera around the nodal point of the lens? You did not state this point specifically,

    You did not mention focal length either.

    I know we have readers who use several of the pano softwares out there.

    My experience is solely with CS4 and CS5, which have worked well for me for single row panos.

    Are you shooting single row panos, or multiple row panos as well?

    What I do, is focus the first shot with auto focus, then keeping the focus, switch to manual focus and avoid touching it. As long as you dont move your tripod, I would think that you would keep your focus. If you use the proper tripod head, and everything is perfect, most of the time you can get pretty flawless results with photoshops photomerge function.
