Starting with version 2.6, digiKam features the Tools ? Maintenance menu which gives you access to tools designed to perform a variety of housekeeping tasks: from scanning for new photos to running a face recognition action. Here is a brief overview of the available tools.
Sharing is caring, and there is probably no better way to share your photographic masterpieces with the world than adding them to the Wikimedia Commons pool. While the project's website features its own tool for uploading photos, digiKam's Wikimedia Export Kipi plugin can come in rather handy when you need to export multiple photos in one fell swoop without leaving the convenience of your favorite photo management application.
Soft proofing is a technique which allows you to see what the photo will look like when printed using a specific printer and photo media (paper, canvas, etc.) without actually printing the photo. Many professional photo processing applications support soft proofing, and digiKam is no exception.
To make this feature work in digiKam, you need to specify color profiles for your display and the output device (e.g., printer). But before you do that, you need to obtain the ICC color profile for your specific printer and print media.
Sometimes the best way to spice up a photo is to make it look faded, and digiKam makes it supremely easy to achieve this effect.
Adding a dash of color tint to a black and white photo can often produce a dramatic effect, and digiKam does have a handful of toning filters for you to try.
But you are not limited to the built-in filters: using digiKam's editing tools, you can easily tint photos using whatever color you like.
