Damselfly is a server-based digital photograph management system designed for organising and searching large collections of images. It places particular emphasis on fast searching, keyword tagging and managing photographs stored in existing directory structures.
The software supports a wide range of image formats, including JPEG, PNG, HEIC, TIFF and RAW files. Its search facilities use filenames, keywords, camera information, dates and other metadata to help users locate photographs quickly.
Damselfly also includes machine learning capabilities for detecting and recognising faces, identifying objects and finding visually similar photographs. Face recognition can operate locally without depending on external cloud recognition services.
A browser-based interface provides access to the photo library from different devices. Damselfly also offers a desktop client that can transfer selected photographs to a local computer for editing in applications such as digiKam.
This is free and open source software.
