Need to quickly off-load photos from your camera and neatly organize them into folders by date? The Fotobasher shell script cobbled together by yours truly can help you with that.
The script copies photos from a mounted storage device like an SD card to the TMP directory, organizes the photos into folders by date, and then renames each photo using the data pulled from the photo’s metadata. Photos are renamed using the YYYYMMDD-HHMMSS-ShutterCount.EXT format, so the resulting file name looks something like this: 19730115-135547-3375.NEF. Fotobasher is configured to work with Nikon D90, but adapting the script to other camera models requires only a few simple tweaks.
If you have Git installed on your machine, you can clone the Fotobasher Git repository using the following command:
git clone git://github.com/dmpop/fotobasher.git
Alternatively, you can download the latest release of Fotobasher from the project’s download page.
To make Fotobasher work on your machine, you need to do some preparatory work. Start with installing the ExifTool utility which the script uses to extract relevant metadata, arrange photos, and rename them. ExifTool is available in the software repositories of many mainstream Linux distributions, so you can install it using your distro’s package manager. On Debian and Ubuntu, you can do this by executing the following command:
sudo apt-get install libimage-exiftool-perl
Next, make the fotobasher.sh script executable using the following command:
chmod +x fotobasher.sh
Rename then the ExifTool_config file to .ExifTool_config and move it to your home directory:
cp fotobasher/ExifTool_config ~/.ExifTool_config
Adding the .ExifTool_config file is required only if you want to include the shutter count value in the file names. In case you use another renaming rule, you can skip this step.
Finally, open the script in a text editor and specify the desired TARGET_DIR value and the correct file format (e.g., RAW, CR2, or JPG).
That’s all there is to it. Insert the card with photos, run the script to download the photos, arrange them into folders, and rename them.
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. Say, you are using an Epson 9880 printer to print photos on the IJMF professional glossy photo paper from Diamond Jet. Grab the appropriate ICC profile from the company’s Resources page. Create the ~/icc directory and move the obtained .icc file into it. In digiKam, choose Settings → Configure digiKam, switch to the Color Management section, and click on the Profiles tab. Select the desired color profile from the Monitor Profile drop-down list (the default sRGB IEC61966-2.1 color profile is a good choice in most cases). Next, in the Color Profiles Repository section, specify the path to the ~/icc directory. Press OK to save the changes and close the dialog window, then restart digiKam.
To enable soft proofing, open the photo you want for editing and choose View → Soft Proofing Options. Select the downloaded .icc color profile from the Profile of the output device to simulate drop-down list, then select the desired item from the Rendering intent drop-down list. This should generally be Relative Colorimetric, but if your printer supports only a limited gamut you may want to try the Perceptual rendering intent instead. Enable then the Highlight the out-of-gamut colors option and select the highlighting color you want. Finally, enable soft proofing by pressing the Soft Proofing On button, and you should see the photo exactly as it would appear in print.
Despite the fact that I’ve been living in Aarhus for almost 18 years, I often get lost in my own city. Last time that happened, I discovered this vintage door sign. According to the missus, the sign dates back to the 30′s. What makes it particularly interesting is that a different font is used for each line (except the first two words). In case you wonder what the sign says, here is the translation: Dealing, begging, carrying goods up the main stairs, and parking bikes and prams is prohibited

So far, we’ve had three (sic!) sunny and relatively warm days this spring, and I spent two of them in our local botanical garden armed with my Nikon D90 and the lightweight budget macro combo.
Despite the unusually rough (even by Danish standards) spring, there were a handful of blooming flowers, including Saxifraga arendsii. These are not the most spectacular flowers in the botanical garden, but they are pretty in their own unassuming way.
I processed the photo in digiKam using a few techniques described in the digiKam Recipes ebook. The photo is published on Wikimedia Commons under the Creative Commons Attribution-ShareAlike 3.0 Unported License.
