[hugin-ptx] Enfuse 4.1.1 CIECAM bug?
I've been trying to track down a problem with enblended images suffering a lack of contrast with respect to the remapped images. It seems that I am not the only one experiencing this problem and it is due to the CIECAM blending default option for input images with colour profiles. Example: http://www.flickr.com/photos/48606216@N00/10135641463/ The area shown is not in an overlapping region so no blending should occur. The input image looks exactly like the right hand side when CIECAM blending mode is turned off. The left shows a lightening of the shadows with the default options. Enblend 4.1.1 Windows 64-bit version from Sourceforge. Windows 7 64 bit 16GB RAM, i7 3770. Lightroom 4.4 and PWP 6.0.10 64 bit. Is the problem due to the forward and reverse mappings of the input colour space to CIECAM02 not being inverse? I would have expected that a non-overlapping region should be mapped in the output to exactly the same values as the input but this doesn't seem to be the case with the CIECAM blending mode.

I don't have an explanation for the difference, but enblend _will_ alter values in non-overlapping areas - The width of the blend is determined by the number of blending levels, so if you want to rule out the blending itself as the source of the problem then you can temporarily set this to -l 1 -- Bruno -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

Hi Frederic, Am Sonntag, 6. Oktober 2013 20:02:20 UTC+2 schrieb Frederic Da Vitoria: The SDK first refused to install, just like the first time it installed. Like the first time, I had to remove the C++ 2010 redistributables in order to reach the window where I could check which options were about to be installed. When checking the compilers, I noted that the checkbox was not working properly: it never unchecks itself. But I also noted that the required space varied and I deduced that when the required space was larger it meant the compilers would be installed. Anyhow, which ever option I chose, this does not work, and opening the SDK prompt gives the message: The x64 compilers are not currently installed. Please go to Add/Remove Programs to update your installation. I googled this and found a solution ( http://connect.microsoft.com/VisualStudio/feedback/details/683852/fail-to-install-windows-sdk-to-add-x64-cross-compiler-to-visual-c-2010-express-running-on-x86-pc-based) telling me not to install the compilers with the SDK but install the compiler SP after. This is what I did. I managed to compile STLport with no error and 45 warnings. I now understand that I don't need this step, Thomas, but that was a few days ago. I installed the SDK and the compiler update some time ago and could not remember all details anymore. (I found this: http://blogs.msdn.com/b/vcblog/archive/2011/03/31/10148110.aspx Don't know, if this helps. But I have also the compiler update installed.) Now I am stuck a little further down the road: I am at the lcms step (once again, I now know this is not necessary, but I believe the issues I find here will block me further anyhow). In Visual C++, I select lcms, right-click and chose the properties. I can change the configuration to Release but the only Platform offered is Win32. This is relatively easy: in the platform dropdown select the configuration manager (I have only a German version, I'm not sure about the English words). Under active platform select new and there then x64. Close the dialog. Now open the properties of each project (right mouse button) and change the platform toolset (under General) to Windows SDK 7.1. This must be done for all projects in the project map. This is some work, but needs to be done only once. (For other libs some more changes are necessary.).

Re: [hugin-ptx] Enfuse 4.1.1 CIECAM bug?
Thanks for the tip about the blending levels. However, even with only a single blending level I get the same lightening of the shadows with the default options. I found a previous post https://groups.google.com/d/msg/hugin-ptx/354rmYe12fA/4cLfTrny11kJ that indicates that the problem could lie with LCMS. Just noticed 4.1.2 on Sourceforge. Just tried it but it looks like it behaves the same as 4.1.1.

After the update of sourceforge I assumed that the old repo is read only. But it is still writeable, and there were an accidental push to the old repo. In another project that I'm following, they handled a similar repo change by removing all files in the old repo, replacing them with a single README, briefly explaining about the new location of the repo. Given the nature of mercurial/hg, the old chances will not be lost.
