Austrians are a very private people, so private that they have encoded their privacy into law, which makes it very difficult to "legally" be a social documentarian in Vienna. Germany is very much the same way with their laws. Now, I could certainly take the time to dive into that topic and it's definitely one that I could write/talk all day and night about, but I've already addressed it before. Now anyone that has perused my photos here or on my Flickr knows that I don't always toe the line and there are times I blatantly cross it (disclaimer: anyone that has ever asked me to delete a photo or not publish it or to take it down has had their request fulfilled immediately and politely), but I always make sure to never show my subject in a disparaging light. If I photograph someone's face, it's because I find it interesting. It's fun to imagine what life experiences resulted in that face.
All that being said, though, I have made very conscious attempts to photograph someone and yet maintain their anonymity. In fact, these are some my favorite photographs because although you're boxed in as a photographer and looking to find a different perspective, you still have a great deal of freedom. You can structure a photograph in many ways. You're forced to look at things differently and that results in interesting things.
Enough text, though, let's look at some photographs.
