ExifTool Support

The famous ExifTool is now supported officially in parallel than the former Exiv2 shared library to handle file metadata. ExifTool is a powerful tool that we will use in special cases to fix metadata dysfunctions that we cannot solve using Exiv2. An ExifTool metadata viewer have been appended to the metadata sidebar everywhere in digiKam. The view works exactly as the Exiv2 version, including the metadata entries filter. ExifTool supports a larger list of file formats than Exiv2.

Better Support of FITS Astro-Photo and MPO Multi-Picture Formats

FITS and MPO, are now fully supported in the 7.3.0 release, including metadata. Flexible Image Transport System (FITS) is an open standard defining a digital file format useful for storage, transmission and processing of data, formatted as multi-dimensional arrays, for example a 2D image, or tables. FITS is the most commonly used digital file format in astronomy. JPEG Multi-Picture Format (MPO) is a JPEG-based format for storing multiple images in a single file. It contains two or more JPEG files concatenated together. Various devices use it to store 3D images, such as Fujifilm, Panasonic, and Sony. Thanks to ImageMagick codec and ExifTool parser working in the background.

New Tool to Export to iNaturalist

A new plugin was developed and tested to export photos to iNaturalist. This web-service is a social network of naturalists, citizen scientists, and biologists built on the concept of mapping and sharing observations of biodiversity across the globe. iNaturalist receive observations of plants, animals, fungi, and other organisms worldwide, and around 130K users were currently active.

iNaturalist describes itself as “an online social network of people sharing biodiversity information to help each other learn about nature”, with its primary goal being to connect people to nature. Although it is not a science project itself, iNaturalist is a platform for science and conservation efforts, providing valuable open data to research projects, land managers, other organizations, and the public.
