Well, it seems that applying gamma 2.2 to the HDR images solves the issue (which is strange on its own). But IMO it can not be accepted as solution

For visualization I tone-mapped them using mai11 operator: https://fliker09.tk/sharedstuff/launchpad/panorama0000.jpg https://fliker09.tk/sharedstuff/launchpad/panorama0001.jpg https://fliker09.tk/sharedstuff/launchpad/panorama0002.jpg https://fliker09.tk/sharedstuff/launchpad/panorama0003.jpg Looks all good. After that I try to stitch them using enblend 4.2 (nft and graph-cut algorithms) and verdandi 2016.2.0 (watershed algorithm): enblend --wrap=horizontal --blend-colorspace=IDENTITY -o panorama_original.exr --primary-seam-generator=nearest-feature-transform panorama000*.exr enblend --wrap=horizontal --blend-colorspace=IDENTITY -o panorama_original.exr panorama000*.exr verdandi --wrap --seam=blend --output=panorama_original.exr panorama000*.exr I again tone-mapped the results for visualization: https://fliker09.tk/sharedstuff/launchpad/hdr/ I hope no commentaries are needed... Next, I decided to tone-map the nona's output: pfsin panorama000$i.exr | pfstmo_mai11 | pfsout panorama000$i.tiff convert panorama000$i.tiff -channel a -negate +channel panorama000$i.tif After that I stitched again: enblend --wrap=horizontal --compression=none --blend-colorspace=IDENTITY --fine-mask -o panorama_original.tif --primary-seam-generator=nearest-feature-transform panorama000*.tif enblend --wrap=horizontal --compression=none --blend-colorspace=IDENTITY -o panorama_original.tif panorama000*.tif verdandi --wrap --seam=blend --output=panorama_original.tif panorama000*.tif And here are the results: https://fliker09.tk/sharedstuff/launchpad/tmo/ Difference is huge... Much better results! Now the question - why so bad with EXR files? Am I doing something wrong?
