Banding on images

Hi All,

Does anyone have any tips for reducing the apparent banding in the images. Camera is set to manual, exposure and focus locked.

Ive only done 2 pano’s so very early days and still learning lots.

Please have a look at the images and let me know your thoughts.

The banding is from vignetting of the lenses, the slight dimming toward the outside edges. You can get rid of it by pre-processing each image in Photoshop or using a stitcher that has the correction built in. Gigapan Stitch 2.0 with .efx will have that feature and will be released soon. Otherwise your pans are perfect. You might want to use a longer telephoto to get more detail, however, every lens can have some degree of vignetting that has to be dealt with. You can do test panos with a 3 × 3 patch of clear blue sky to see the effect and the result of corrections. More overlap in the photos can reduce it, but it is better to apply a correction that is specific to the lens. Good luck.

I think I’m having the same problem. here’s my gigapans that I have used with the Gigapan Stitch 2.0.


I just can’t get those lines to go away.

Stephen: With the ~30% horizontal overlap you’ve got I’m very surprised you’re still seeing this much vignetting, especially using the vignette correction setting in Stitch Efx. I wonder how much vignetting your original input images had? Was it noticable?

There may still be a way to fix this for your original set of images – Paul Heckbert should really have a look at these. I’m no expert in dealing with this problem, but I’d echo what David Pivin suggested – it’s probably worth doing the experiment he suggests shooting at clear blue sky. If I were in your shoes, I’d probably try to increase the overlap to 40-50%. If that still doesn’t solve it you’ve got some other problem I haven’t seen before, perhaps relating to this specific lens/zoom combination.

Good Luck!
