I have recently been working on some panoramas. I am using CS3 and it performs an excellent job on stitching images together. Some of the scenes I am working on need blends of more than one exposure. My initial idea was to stitch panoramas for different exposures and then blend them. That does not appear to work unfortunately. CS3 stitches the images differently, depending on the exposure. I cannot therefore blend two panoramas of different exposures since they are not exact copies of each other.
Does anybody know how to deal with this? I have spent a lot of time on this and I don't know what to do anymore.
I have used AutoPanoPro in the past. It has a feature built in that will adjust the exposure to some degree to match the photos being merged. It should also work to stitch images of different exposures that you have already adjusted in CS3. Give it a try, I think they have a free download, and the program was about $99.00 to purchase.
Why not blend the bracket shots, and then stitch ? For example with AutoPano as suggested or with PTGui (my preferred software, adjusts exposure shifts to some extent, as AutoPano).
Before I blend exposures for later stitching, I take care to match the bracket shot histograms as close as possible in my RAW converter, best suited for this purpose is CaptureOne, but ACR and others should work also.
Carsten, thanks for that. I decided to do something similar: As you said, blend the bracket shots before you stitch. When I blend I use TK's luminosity masks, and I make sure that I blend the same way throughout the shots that will make up the pano. E.g., if you use expanded midtones for one shot that forms part of the pano, I use it for all other shots too. And it worked amazingly! I worked on a pano yesterday and the resultant stitch looked seamless. It is more work than simply blending the panos themselves, but it works.

I 2nd Alice's suggestion. I only use AutoPano and the majority of the time I am pleased with the results.
