Sometimes, the easiest way to geotag photos in digiKam is to copy and paste geographical coordinates from an existing photo. I usually use Google Photos for that, as it conveniently displays geographical coordinates of the currently viewed photos in the information sidebar.
There is only one problem with this technique: copying and pasting the geographical coordinates directly doesn't work.
Hot on the heels of the major digiKam 5.x.x release comes a thoroughly revised version of the digiKam Recipes book. Although it doesn’t include any new material, the entire content and all screenshots have been revised and updated to reflect changes in the latest version of digiKam. In addition to that, some obsolete content has been removed. But a shiny new book cover featuring catchy colors makes up for that.
Speaking of digiKam releases, the upcoming version 5.3.0 will be available as an AppImage 64-bit package. Continue reading
Like many photographers, I have a handful of hand-made favorite presets (most of them are included in the Daily Curves Set) in my photographic toolbox. But there is one preset in particular I use more often than others. I named it Spektrum, as it’s inspired by images from the Spektrum Berlin photo book by Matthias Heiderich.
digiKam is the cornerstone of my photographic workflow. This powerful and versatile photo management application has all tools and features necessary for transferring, organizing, processing, and managing photos, RAW files, and videos. But even though digiKam can handle practically any photographic task you throw at it, there is still room for optimizing and improving parts of the Linux-based photographic workflow. Continue reading
A new release of digiKam Recipes is ready for your reading pleasure. This version introduces the Basic Concepts Explained appendix that covers key terms and concepts used in digiKam. Currently, the appendix contains information about chroma subsampling, cor (bit) depth, hue, saturation, brightness, and vibrance. I plan to gradually expand the appendix with time.
When configuring saving settings for the JPEG format in the Saving Images section of the Configure digiKam window, you can choose between medium and high chroma subsampling, or disable it altogether.
But what is chroma subsampling and what does it do? As you may know, JPEG is a lossy format, which means that it trades quality for a smaller size. One of the methods for achieving a smaller size is to store color information (chroma) at a lower resolution than brightness (a.k.a intensity or luma) data. This is possible due to the fact that the human eye is less sensitive to color than brightness, so discarding color information doesn't produce a perceptible loss of quality.
A new release of digiKam Recipes is ready for your perusal. This version features the new Use Exposure Indicators recipe along with the updated Find the Shutter Count Value with digiKam recipe. Astute readers will also notice the new cover. That's all there is to it this time around.
