The latest issue #6 of c’t Digital Photography features an in-depth article about digiKam by yours truly. c’t Digital Photography is a relatively new quarterly magazine published by Heise, one of the most respected magazine publishing houses in Germany.
For my money, c’t Digital Photography is the best photography magazine on the market. And I’m saying that not because I write for it. The magazine caters for serious amateurs and professional photographers alike, offering high-quality articles covering a wide range of topics: from macro photography and panorama stitching to lens adapters and lens correction techniques. The current issue #6, for example, is chock-full of great articles, including excellent pieces on DIY studio gear and macro focus stacking. Linux users will also appreciate that c’t Digital Photography covers Linux-based photography tools as well as open source software for other platforms. In fact, issue #4 of the magazine features a comprehensive article on photography software for Linux, while issue #5 covers photography apps for iOS and Android.
c’t Digital Photography is published both in German and English, and your magazine subscription is available internationally at reasonable rates. The magazine’s editor has kindly provided me with two extra copies of the English version of the current issue which I’ll be more than happy to share with Scribble and Snaps’ readers. Leave a comment to this post, and I’ll randomly pick two lucky recipients.
Need to quickly geotag a bunch of photos taken at a specific location? ExifTool is your friend. Using this powerful command-line tool, you can geotag multiple photos with a single command. Before you proceed, make sure that ExifTool is installed on your machine. To install ExifTool on Ubuntu, execute the sudo apt-get install libimage-exiftool-perl command. Next, you have to obtain the longitude and latitude of the desired geographical location, and feed the coordinates to ExifTool as follows:
exiftool -GPSLongitudeRef=E -GPSLongitude=139.7513889 -GPSLatitudeRef=N -GPSLatitude=35.685 *.jpg
This command will geotag all JPEG images in the current directory. If you are running Windows, download the latest version of the ExifTool executable and rename it as in the example below:
exiftool (-GPSLongitudeRef=E -GPSLongitude=139.7513889 -GPSLatitudeRef=N -GPSLatitude=35.685).exe
Drag and drop the photos you want to geotag onto the executable and ExifTools will do the rest. Besides GPSLongitudeRef, GPSLongitude, GPSLatitudeRef, and GPSLatitude, ExifTools supports a number of other tags. Check the GPS Tags page for further info.
