A very late reply, but going through my unread mails I just saw your example images and I have seen very similar, washed out colors when camera response curve parameters had been optimised. Can you try reseting them to zero as well, or just post the pto file, so we can see if those parameters were non-zero?

Michael, Something else you can try, add --no-ciecam to the commandline for enblend and enfuse, see if that makes a difference.

My workflow is this: I load the pictures and and then click the Align button so it will find all control points. Then I fix some control points that shouldn't be there, reset the yaw pitch and everything and then optimize only X Y and roll. I set EV on all images to 0, because they were taken using the exact same camera parameters. -- You received this message because you are subscribed to the Google Groups Hugin and other free panoramic software group.

[hugin-ptx] Re: colors and brightness change when stitching
What's your workflow? Are you using the assistant mode? Is Photometric optimisation being applied to the aligned images. You can reset the exposure values in the Camera and Lens tab. Or else the exposure values in the EXIF are not what you want them to be. In that case, make the exposure value the same for each image under the Camera and Lens tab, Photometric sub-tab. In the preview window, you can change the global brightness of the output image. Hugin will usually pick some middle value but for exposure blending you can manually change the exposure to get highlight or shadow detail. Cheers, Daniel.

so, is there a solution to use images with a certain profile, having as output an image with that same profile?

Re: [hugin-ptx] Re: colors
Also your image editor should not be set to assume a certain ICC profile when opening a file that doesn't contain such information. A proper setting would be to give you the choice of available profiles that the program can assign while loading the file. After that just save the file and it will contain a proper color profile. If you want to use exiftool for this here is a list of utilities that may help you: http://owl.phy.queensu.ca/~phil/exiftool/#links Carl Eric O'Brien schrieb am 10.11.10 06:16: If Hugin is not retaining the profile information, it should be more of an irritation rather than a significant problem. Just do all your work as usual while ignoring any funny colors. When you have created a final output file, just open it in your favorite image editor and assign the it the correct profile. That is, probably the PIXEL data has not changed, only the notation of what profile is being used. eo On Nov 9, 2010, at 5:40 PM, sneike wrote: so, is there a solution to use images with a certain profile, having as output an image with that same profile?

[hugin-ptx] Re: colors
The original jpg has AdobeRGB color profile. Using sRGB could fix your problem.
