those images are of course just a small section of the panorama I cut out to illustrate the problem. the original is much larger.
Your second image looks motion-blurred and/or blurred because of lens issues.
Were there multiple exposures from which Photomerge could have chosen that particular section of the image? I ask because it looks like the noise pattern is completely different in the one than the other. I'm guessing it chose differently which shot to use for that area.
Are these converted directly from raw files during the Photomerge?
I don't know what to suggest except perhaps dialing in more noise reduction in the raw converter and seeing if that will help Photoshop to pick the sharper of multiple overlapping areas.
P.S., For what it's worth, I've been doing Photomerges in Photoshop CS6 today and not having any problems with sharpness.
They were both created by using the exact same RAW files so it is not possible that is a lens issue (all I changed in the RAW files was the temperature and tint). I only took that set of pictures once so it is not possible I accidentally used the wrong ones.
I also tried to use .TIFF files with some sharpening, but with no change in result.
ok I used photomerge to create a panorama in CS6 using the same images (entirely different from the terra cotta warrior pictures above, another set of pictures I took a month later) I used to do the same in CS5 and with those images I am getting good results.
with the terra cotta warriors above though it just looks terrible even though the images I am using look great. I suppose I could put CS5 back on my computer, do this one photomerge, and then take it off? It seems like there should be a better solution though ...
bit of a weird frustrating problem ...
Steve, the deal is that you have two or more images that have the particular section of the subject material in them, and the different versions of Photoshop for whatever reason chose to use different ones in the stitch.
My theory is that Photoshop CS6 has become confused by the noise in the image and thinks the one that's actually blurrier is just as sharp and has gone ahead and used it.
Try the noise reduction thing I mentioned.
If you want to make the original files available I can look into it further for you and may be able to find another workaround.
Noise reduction doesn't work. Looking closer at the source images I can see that one of them is a little out of focus. I can see that is using a lot of the out of focus file and not very much of its in-focus neighbours. Is there a way to get it to get photomerge to give a high priority to the neighbouring image files or a low priority to the one that has problems?
Thanks for your help by the way.
