Shotwell

Introduction to Shotwell​

Shotwell is an open-source digital photo organizer and image viewer designed for the GNOME desktop environment. It allows users to import photographs and image collections, organize files with tags, dates, and ratings, and inspect full-resolution imagery efficiently.

Shotwell provides essential non-destructive photo editing features, including cropping, rotating, color adjustments, and red-eye reduction. It is a lightweight and convenient tool for managing visual data, field photographs, or remote sensing image collections directly on the cluster. For more details, visit the official Shotwell documentation.
