Hi,

as the title read,


Getting banding in stitched panos.


I am setting everything to manual and yet still banding.


Any way to prevent it?

Are the bands there in each piece before you do the stitching? Or is your stitching software introducing them to the image?

If you use PS, the I find after I stitch in PS I need to flatten the image

Can you show us an example? I found that when I used PSE 8 (I think) I got banding but when I used Hugin on the exact same images, no banding at all.

Are you using a CPL on a wide angle? If your sky varies greatly in color, it may be hard to stitch them unless you do a lot of overlap.

perhaps the banding is due to the differing exposures between all the shots - hence you get the banding of different exposures.

Freeware like Hugin can solve that and blend the colours to give a 1 colour look.

assuming that the banding is based on exposures.

Well, welcome back, two weeks later! You haven't really answered any of the questions. I gather what you mean is that there isn't "banding" per se; what you mean is that there are seams showing between the frames that you stitched...is that correct? If so, a setting sun is very unlikely to be the culprit. I've done panos with a very low sun many times without problems, so the problem probably lies elsewhere.

Are you sure that nothing happened to the exposures in your processing software that might have changed each one ever so slightly? Do you perhaps have an auto settings applied when you import to Lightroom or whatever you use? Do you apply lens corrections? What happened to the files after they left the camera? Are you absolutely certain that your exposures were locked down completely at the time of capture?

Also: how much of an overlap did you allow between frames?

Applied lens corrections, made adjustments as usual in ACR, save as tiffs, stitch and the result looks good, minus in the sky very faint lines that in my view look like banding, where you see blue sky, next to is a very faint band of light pink or magenta.

OK, but are we talking about bands that match up with where the seams of the images are, or bands that cut across the stitched images? Perhaps you could post an example?

The bands have nothing to do with the stitch line. Will see if i can post an example
