Google am\u00e9liore son application Photos pour la rendre encore plus performante. Avec une nouvelle mise \u00e0 jour, les utilisateurs peuvent d\u00e9sormais retoucher leurs photos HDR sans compromettre leur qualit\u00e9.<\/strong><\/p>\n

Retoucher<\/strong> des photos HDR<\/a> sur un smartphone est souvent synonyme de frustration<\/strong>. Ces images, qui capturent une vaste gamme de luminosit\u00e9, perdent souvent de leur \u00e9clat<\/strong> apr\u00e8s des modifications. En effet, lorsque des outils de retouche sont utilis\u00e9s, les photos passent de HDR \u00e0 SDR<\/strong>, ce qui entra\u00eene donc une perte de contraste<\/strong> et de luminosit\u00e9<\/strong>. Les zones lumineuses perdent de leur intensit\u00e9, tandis que les ombres deviennent plus fades, ce qui r\u00e9duit fortement la qualit\u00e9 visuelle.<\/p>\n

Pour r\u00e9pondre \u00e0 cette probl\u00e9matique, Google vient d'introduire un mod\u00e8le d\u2019IA dans son application Photos. Ce dernier permet de conserver la qualit\u00e9 HD<\/strong>R m\u00eame apr\u00e8s des modifications complexes. Par exemple, si vous utilisez la Gomme magique<\/a> pour supprimer un objet g\u00eanant dans une photo, Google Photos ajuste automatiquement les d\u00e9tails lumineux et sombres pour \u00e9viter tout “\u00e9crasement” de la dynamique visuelle. Cela garantit que votre image garde ses contrastes intenses<\/strong> et ses couleurs vives, m\u00eame apr\u00e8s des modifications<\/strong> importantes.<\/p>\n
