I want to install a package (DigiKam), but it has a lot of dependencies. If I decide I no longer need this software and uninstall it, will the now unnessary dependencies be removed?
If not, how can I do it manually?

You can use the command
apt-get autoremove. It will remove packages that are installed as automatic dependencies, but are not depended anymore.
apt-get has a flag
--auto-remove that can be used to automatically remove the automatically installed packages when removing a manually installed package:
apt-get remove --auto-remove packagename
Certain other tools are also capable of doing this, for example
aptitude will automatically suggest that you remove the packages that have been orphaned.
The automatically installed packages tracking is built in to apt so the tracking should work no matter which tool you use to install the packages.
I use ubuntu tweak, it has a very effecient app cleaning utility that has never removed more then it should.
I had the same problem. Here is what I did:
sudo apt-get check
This command will provide the name of dependencies. E.g. my system had
Then enter the following command
sudo apt-get remove --auto-remove chromium-browser-l10n
It will remove the dependencies completely from your system
