The doors of Vienna provide sufficient subject matter probably for many days of photography, and even in the small number of hours that allowed me to visit a really little part of this city, I found more than suitable for series of postings. So I will probably make a small gallery, which also meets my growing interest for images in a series. Diptychs and Triptychs are a bit special in this sense as they are designed to be viewed together (and therefore I find it more complicated to come up with good ones), whereas small series allow for greater variance while still following a common basic idea. And, the latter are easier to show on web and the restricted screen area available for most viewers.
