What color profile are you using when exporting? Try using sRGB, and see if that works better.
Ligthroom is color managed, and will show you the correct colors, provided that you have a correct monitor profile.
Most other programs are not color managed, and may not display correct colors, this is particularly the case if you have a wide gamut monitor, in which case you should only use color managed programs to view your images.
If this doesn't answer you question, please post screenshots that show the color difference.
Oui j'utilise sRGB à l'exportation. Comment je sais si mon profil moniteur est correct??
To create a custom profile for your monitor, you have to use a hardware calibrator.
In many cases, using sRGB (or Adobe RGB for a wide gamut monitor) will be good enough.
Are you on Windows 10?
What is the make and model of your monitor?
And could you please post screenshots that show the color difference?
Are you saying that you calibrated the monitor with a hardware calibrator?
Your monitor is not wide gamut, so the image should look roughly the same in non-color managed programs as in Lightroom.
This indicates a defective/corrupted profile, so try setting the monitor profile to sRGB:
Press the Windows key+R, type colorcpl, and hit Enter.
Add the sRGB profile, then set it as Default profile. See screenshot below.
J'ai essayer même soucis . Oui calibrer avec une sonde professionnel.
Dans les deux cas la photo diffère toujours du logiciel a l'exportation
Please try setting the profile to sRGB like I described above. It lets you know quickly if there is something wrong with the profile - it could have become corrupted.
Another point is that version 4 ICC profiles are incompatible with Lightroom, so you need to set the calibration software to use a version 2 profile.
J'ai utiliser la version 2 et je n'ai plus le soucis . Un grand merci à vous pour votre aide .
