While in Berlin, I shot a roll of C41 black-and-white film from West Yorkshire Cameras. Alas, I’m not particularly impressed by the film. The contrast is somewhat low (I had to increase it in digiKam), the grain is not very pleasing, and the last 3 out of 27 exposures were duds. Oh well, back to the tried-and-tested Ilford XP2 Super 400, then.

On a related note, I had a chance to visit the FOTOIMPEX store. It specializes in all things film photography and carries a wide range of films and film photography-related supplies. I’ve added FOTOIMPEX to the Shoot Film In wiki.
To keep track of film development labs and stores that carry film in cities around the world, I’ve set up a no-frills wiki. While this is a strictly personal project, I thought I’d make it public in the hope that other film photographers might find it useful and will be willing to contribute. Interested? Then visit the ShootFilmIn wiki.
There is not much info in the wiki at the moment, but I plan to add more content to it. I hope you’ll do the same.
There are plenty of reasons to choose Debian, but having the most recent versions of your favorite applications is not one of them. Software updates trickle down to the stable version of Debian very slowly, which means that packages in the distro’s repositories are likely to be a few versions behind the current releases. digiKam is no exception: the Debian stable repositories contain a version of digiKam which can be considered outdated. However, if you don’t mind the risk of making the Debian system unstable, or even breaking it altogether, you can opt to upgrade the distro to unstable and then install the latest version of digiKam from the experimental repositories. (Note: all commands mentioned below must be executed as root.)
The first step is to upgrade Debian to unstable. To do this, run the nano /etc/apt/sources.list command to open the sources.list file in the nano editor. Disable stable and security repositories as follows:
Add then the unstable repositories:
Press Ctrl+X to save the changes and close the editor, then run the commands below to update repositories and upgrade the distro:
apt-get update && apt-get dist-upgrade
Once you’ve done that, open the sources.list file for editing again and add the experimental repository:
deb http://ftp.debian.org/debian experimental main contrib non-free
Save the changes and run the apt-get update command. You can then install the latest version of digiKam from the experimental repository using the following command:
apt-get -t experimental install digikam
If everything goes smoothly, you should have the most recent release of digiKam installed on your system.
If you are looking for a no-frills depth of field calculator app for Android, you can do much worse than giving the DoF Calculator a try. Released under the GPLv3 license, this app has the virtue of doing one thing well: calculating the depth of field and limit values for any given camera model, lens focal length, and distance to the subject combination.
DoF Calculator is not available in the Google Play Store, but you can either sideload it using the latest APK package from the project’s website, or install the app through the F-Droid market. Unsurprisingly, DoF Calculator is very straightforward in use: pick the desired camera model, focal length, aperture, and the distance to the subject, and tap the Calculate button. The app then returns three values: near and far limits along with the total depth of field.
