For this project, we'll use a photo of the famous Sagrada Familia cathedral in Barcelona, Spain. The photo was taken with a Canon PowerShot S90 camera, and the RAW file exhibits several obvious flaws, including visible barrel distortion, underexposed areas, and noise. In other words, this particular RAW file is perfect for tweaking in digiKam.
Need to quickly push photos in digiKam to a device on the same network? Provided the device supports DLNA, you can do this using the DLNAExport Kipi plugin. Choose Export ? Export via DLNA to open the DLNA Export wizard. From the Choose the implementation drop-down list, select either HUPnP API or miniDLNA. Both options have their advantages and drawbacks.
A new version of the digiKam Recipes ebook is available for download. The following material has been added since version 3.9.39:
- Create a Bleach Bypass Effect
- Export Photos via DLNA
- Process Film Negatives
- Calibrate and Profile Monitor for Use with digiKam
- Use Photoshop Curve Presets with digiKam
- Import Photos from a Remote Server into digiKam
As usual, the new release features minor fixes and improvements. Continue to read
While digiKam is first and foremost an application for processing and organizing digital photos, it also features tools for working with film negatives.
To calibrate a monitor and generate a color profile for it on Linux, you need two things: a colorimeter and color profiling software. High-quality professional colorimeters tend to be rather expensive, but you can use the excellent open source ColorHUG device instead. When it comes to calibration and profiling, the displaycalGUI software is the perfect software for the job. It provides a graphical user interface to the display calibration and profiling tools of the Argyll CMS open source color management system.
Using commands under the Import menu, you can pull photos from a variety of sources, including remote servers. The latter functionality in digiKam is provided through the KioExportImport Kipi plugin which supports common protocols like FTP, SSH, and SMB.
While digiKam can't handle Adobe Photoshop curve presets directly, the application supports curves in the GIMP-compatible CRV format. So if you want to use Adobe Photoshop curve presets with digiKam, you have to convert them into .crv files — and the acv2gimp.py Python script can help you with that. Continue to read
Thanks to digiKam's geocorrelation capabilities, you can geotag photos using a GPX file created with apps like Open GPS Tracker. But there is also another way to use your Android device for geotagging. The built-in camera app of most Android devices is capable of geotagging photos. This means that you can take a geotagged snap with the Android camera and then transfer geographical coordinates from it to other photos using digiKam. So next time, when you are done shooting with your main camera, remember to take a reference snapshot with your Android device (make sure that the geotagging option is enabled).
Being a do-it-all kind of application, digiKam is suited not only for performing the mundane tasks of organizing and editing photos. The application also offers a specialized tools for more advanced operations: from blending bracketed photos to stitching panoramas. The latter functionality in digiKam is implemented as a Kipi plugin which relies on Hugin, a set of powerful tools for processing photos and stitching them into panorama images. The plugin wraps Hugin features into a user-friendly interface which dramatically simplifies the process of turning multiple photos into a panorama.
