P.S. I see you are new to the community. One recommendation when posting images. Please use the Insert Photo button instead of the Insert Attachment. Use the Insert Photo for images, use the Attachment for long documents and PDF. That works better, and a few advanced members cannot or will not open those attachments.

Hi John,
Vous trouverez ci-joint les informations demandées.
Malheureusement, je n'ai pas retrouvé le fichier .XMP dans le dossier où se trouve le fichier .arw.
Il doit etre dans un dossier annexe mais où...

When I open that catalog and click on the Import step, I see "Profile missing" too:
At the time the photo was imported into your catalog, you had set a raw default in Preferences > Presets that set the Profile to Camera Standard, so that profile was applied to the photo. Your screenshot above shows the raw default in Preferences > Presets as Global: ISO Variable, so likely the preset ISO Variable has the Treatment & Profile option checked, and it includes Camera Standard.
But the Sony A7 IV (and other newer Sonys) doesn't have a profile named Camera Standard -- it is called Camera ST. So when you imported the photo, LR tried to apply the raw default Profile: Camera Standard to the photo, but since there is no such profile for that camera, LR reports "Profile missing".

"All of my images end up underexposed by 2 stops."
This issue isn't related to the missing profile error discussed above. Rather, I think you're seeing the confusing effect of having set the camera's Picture Profile to PP8 or PP9, which is Gamma S-Log3 (PP8 or PP9).
The camera's exposure mode was set to Manual, and the photo was exposed at 1/400, f/13, ISO 1250, which is an Exposure Value (EV) of 12.4. According to this article, that might be somewhat underexposed for an outdoor photo taken about an hour after sunrise on a clear day (I'm assuming this was somewhere in the French Alps?).
The appearance of the photo in LR with Profile: Camera ST looks very similar to the appear of the photo in Sony's Imaging Edge utility with its ST setting:
This confirms that LR is interpreting the raw photo correctly. The histogram in Imaging Edge indicates that the photo is underexposed.
I think what might be misleading you is that the photo was taken with the camera's Picture Profile set to PP8 or PP9, gamma S-Log3. This picture profile, like the other "s-log" profiles, is intended to encode video with an increased dynamic range, and such video needs to post-processed with software that understands that encoding. Picture Profile doesn't affect the pixel values recorded in the raw image, and LR ignores Picture Profile entirely.
However, the camera does encode JPEGs with the currently selected Picture Profile, including the JPEG embedded preview recorded in the raw photo:
The live preview on the camera's screen and view finder also uses the current Picture Profile, so the screenshot above is what you would have seen when you pressed the shutter. The flat and neutral appearance of that preview is caused by the S-Log3 gamma encoding, but it's not at all representative of the appearance produced by Adobe's or Sony's camera profiles.
So you should set Picture Profile to Off when shooting raw.
Bonjour,
J'ai ajouté il y a plusieurs années maintenant un parametre de gestion des ISO qui automatise une serie de réglage sur cette partie de développement.
Cela n'avait pas d'influence sur le rendu jusqu'ici...
