sfage Posted June 24, 2008 Share #1 Posted June 24, 2008 Advertisement (gone after registration) Hi! I am trying to create a panorama composition. It consists of 9 shots --and I was very careful with the exposure consistency. I have used advanced blending -and it's better- but that doesn't seem to work... as perfectly as I'd like. When I ask Pshop to generate the composition, it puts the image together correctly but I get a certain amount of "banding" across the image. It's quite strange -- I would understand if the exposures were wrong; the "banding" would draw a straight line of difference from shot to shot.... but it's not a straight line. It looks a little like: / / / / / / / / / It is a difference in brightness at an angle from top to bottom. but at the bottom, the blending is perfect. Suggestions?

troyfreund Posted June 24, 2008 Share #2 Posted June 24, 2008 I assume the banding is through the sky, where the exposure difference would show up more easily. Sounds like you're gonna have some manual retouching to do on this shot. Check out Panorama Factory--it's a very reasonably priced software and gives you a lot more manual control than PS does. I've only just started using it and am real impressed. Troy Link to post Share on other sites More sharing options...
ho_co Posted June 24, 2008 Share #3 Posted June 24, 2008 sfage-- The 'banding' may just be PS's way of working. In my experience, Photoshop doesn't match edges of lenses vertically, but at an angle across the image. In my experience, getting a fully acceptable panoramic image from any automated program is a rare occurrence. You may find that you can handle the merge better by doing it manually. You might at least want to set Photomerge not to flatten the image, but to leave the layers separate for you to massage. As Troy said, at a minimum it sounds as if some patching is going to be necessary. Good luck! Link to post Share on other sites More sharing options...

You might at least want to set Photomerge not to flatten the image, but to leave the layers separate for you to massage. Good luck! I've had good results "hand-massaging" the image with the gradient tool applied to the layer mask. At least, you can get a smooth color transition. I've always done this on a hand-merged panorama. Once the layers are lined up, if you drag horizontally on the overlap area with the shift key down, you will get a smooth transition on the mask. The other details below the sky will probably need brush and/or eraser corrections on the mask to make them look right. You can find an example here: Rapeseed Field, or here: Preveza Waterfront.

richam Posted June 25, 2008 Share #6 Posted June 25, 2008 One other thought. I've found it's much easier to line up the images or use the photomerge successfully if there is no wide angle "distortion". I try to use 50mm or longer lenses for the original capture. If you have used wider lenses, photomerge will get very confused and you'll be stuck hand massaging the images with very minimal overlap. Not impossible, but difficult.

troyfreund Posted July 8, 2008 Share #7 Posted July 8, 2008 Advertisement (gone after registration) Hey Folks, I"ve been playing with the Panorama Factory software recently and thought I would just quickly share with you a pair of pics---one from Panorama Factory and one from Photoshop CS3. Which one is "better" is pretty subjective, I think, but it sure is interesting to see what two softwares do with the same nine origin files. The first file is from Panorama Factory and the second is from PS-CS3. Files captured with a R8/DMR and 50mm Sumicron. Troy Link to post Share on other sites More sharing options...
