Batch Settings
L'ERF, ou Epson RAW Format, est le conteneur numérique privilégié par les appareils photo Epson pour capturer l'intégralité des données brutes du capteur. Il offre une flexibilité maximale pour la post-production, permettant aux photographes et graphistes d'ajuster précisément l'exposition, la balance des blancs et la colorimétrie sans perte d'information. Cependant, sa nature propriétaire et sa taille conséquente le rendent peu adapté au partage en ligne, à l'intégration dans des documents administratifs ou à l'affichage rapide. C'est là que le format JPEG intervient : universellement reconnu, compressé et optimisé pour le web, il est la norme de facto pour la diffusion d'images. Convertir vos fichiers ERF en JPEG devient alors une étape essentielle pour concilier la richesse du RAW avec les impératifs de compatibilité et de légèreté.

- Intégration d'images dans des rapports d'audit pour l'administration
- Partage rapide de maquettes visuelles avec des clients dans le design
En Suisse et au Québec, où la gestion des archives numériques est rigoureuse, la conversion ERF vers JPEG est souvent accompagnée d'une conservation de l'original RAW pour des raisons de pérennité et de traçabilité des données brutes.
