Hi, I am Steven Lek. I'm uploading pictures to Wikimedia Commons since 2005. All my pictures can be used freely, but sometimes you need to credit my name as a part of the Creative Commons license.
At the moment I'm using a Samsung NX2000 and a Nikon D7000 to shoot pictures. You can check my portfolio at Flickr: 
Please notice that some of my pictures have also been uploaded to other photo platforms, and sometimes with other license requirements, for instance on Google Maps, Panoramio and Flickr. In this case, you can choose the license that is most convenient.
