Damselfly

Damselfly is a server-based Digital Photograph Management system. Damselfly is designed to manage a large, folder-based collection of photographs, with a particular focus on fast search and keyword-tagging workflow.

Damselfly includes powerful Machine Learning functions which can help you identify photographs and their subjects, including face detection, face recognition and object detection - allowing you to tag people once, and have Damselfly identify other photos in which they appear.

The user-interface and workflow is loosely based on the much-loved Google Picasa app, with a basket to select images for export and other types of processing. Damselfly also provides a desktop/client app which gives closer integraton with your laptop or PC, allowing you to quickly sync a selection of images from the Damselfly basket to a local folder, for editing etc.

• Fast keyword tagging workflow with non-destructive EXIF data updates (using ExifTool) - so JPEGs are not re-encoded when keyword-tagged
• Face detection and recognition, and object recognition in images
• Multi-user support with user accounts, and role-based entitlements (e.g., users with ReadOnly role are prevented from keyword-tagging images)
• Download/export processing to watermark images ready for social media, or sending via Email etc.
• GeoLocation with map display of photo locations where metadata exists
• Selection basket for saving images from search results:
  • Images within the basket can be downloaded, exported for use within Digikam/PhotoShop/etc., or uploaded to Wordpress
  • Baskets can be user-specific, or shared with other users
• Server-based deployment, with a web-based front-end UI, so the image library can be accessed via multiple devices without having to copy catalogues or other DBs to local device storage.
• Exclude images from Damselfly scanning by adding a .nomedia file in any folder.
• Themes
• Completely automated background indexing of images,
