Lightroom et sous-exposition A7IV

Bonjour à tous,

Je rencontre un probleme lors de l'import de mes fichiers RAW de mon Sony A7IV dans Lightroom.

La totalité de mes images se retrouvent sous-exposées de 2 diaphs.

Je précise que j'ai déja exploré la piste "DRO" et confirme que l'option est bien en off sur mon boitier.

Je vous joins une photo de l'A7IV ainsi qu'une provenant de mon ancien boitier l'A7III pour l'exemple.

Les 2 images ont été réalisés dans les mêmes conditions d'éclairage et la limite ISO de mon A7IV est de 3200 ISO.

 

Merci par avance pour votre aide et bonne journée à tous !

 

Jérémy

    In LrC /Preferences/Presets/ in the RAW Defaults section, anything other that Adobe Default? Perhaps the other camera is set to be used for this when it is used?

    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...

    So, is that the issue?

    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 GoldingD, Thanks you for your reactivity.

    About the error profile, that is a good question ! 🙂

    Since the latest update i have this message.

    When i change manualy to other profile, nothing change on the picture.

     

    Thanks you for the advice, i'll pay attention to that if i need to post picture again 🙂

    The translation of that part of the Basic panel:

    Profile: Camera Standard
Profile missing

     

    Very curious, since LR provides camera-matching profiles for the Sony A7 IV.  Some next troubleshooting steps:

     

    1. Do Help > System Info and let us know the precise version of LR you're running.

     

    2. In Library, select the problem photo and do Metadata > Save Metadata To File. Then upload the .arw file and its .xmp sidecar to Dropbox, Google Drive, or similar and post the sharing link here. That should give enough clues as to what's going wrongl.

      What is going on in your Treatment Panel? Some error with the profile?

       

      Also, what is shown in the History Panel???
