Très bien !
J'avais entretemps posé la question au service client d'IRIX qui m'a répondu - voir ci dessous - que la correction de profil fonctionne avec toutes les versions de LR ou Photoshop/Camera Raw.
Hello Bruno,
Thank you for contacting us. The lens profiles for IRix 11mm and Irix 15mm works the same with any LR or PS/ACR version.
However, the storage location of the profiles may vary depending on the program version and user settings. In most cases, however, the settings should be the same as for the guides we published on youtube.
