Hello,

Je me mets à photographier en mode raw, j'utilise rawtherapee (difficilement, mais ce n'est pas la question). J'ai remarqué en regardant les exifs de photographes que beaucoup utilisent lightroom. Pourquoi ?

et je posait la question suivante: Peut on comprendre en lisant un exif les modifications faites avec Lightroom ?

par exemple:
