/r/German is a community focused on discussion related to the learning German language. It is also a place to discuss the language at large and for the kinds of submissions that elaborate on the reasons why we're interested in German, where they're not geographically specific like /r/DE, /r/Austria or /r/Switzerland. Enjoy your time on /r/German! :)
/r/photography is a place to discuss the tools, technique and culture of photography. This is not a good place to simply share cool photos or promote your work, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
