User AndreasPraefcke from Ravensburg, Germany, mainly working at de.wikisouce and de.wikipedia.
In Commons, I am trying to categorize images thematically, especially paintings and other images of art, see Category:Art by subject. Other interests are Theatre buildings, Concert halls, Gardens, Category:Organs, my hometown Ravensburg, the region of Upper Swabia and Lake Constance, and historical images of pretty much all kinds.
I have uploaded numerous of my own photos of buildings, churches and sculptures, own scans of public domain images, and images of public domain works of art from the web (especially from auction and museum catalogs). See my Gallery. I have also uploaded some of my grandfather's photos.
License issues 
|If you want to use any of my photos found in Commons, you do not have to use the GFDL license (which would imply quoting the whole license even when used in printed works - what a nightmare of red tape!). I hereby license all my photos in commons also as "CC-BY-3.0", so you only have to note "Photo: Andreas Praefcke" or something similar whenever you want to use a picture.
All my photographs are under a free license and can hence be used without any cost. If you want to publish the photos and absolutely want to pay something for their use, please consider a donation towards the restoration of the choir organ in Weingarten (see www.chororgel.de) or the Deutsche Stiftung Denkmalschutz, or the fundraising organizations of museums and churches that take care of the depicted artworks. International users, please donate to a charity of your own choice.
