Below there is a list of some websites that I'm using, either as a member or as an interested reader.
They all provide interesting material, are educational and most of the times fun to visit.
Photodrome - a forum for photolovers, mostly Netherlands and Belgium members (Dutch spoken)
Fotoworkshop De Ronde Venen - the website of my local photoclub (Dutch spoken)
Visions Libre - a Facebook forum for artloving people, with members that contribute a constant highlevel quality stream of photo's.
It is also a publisher with regular magazines, promoting the work of the contributors.
Werk aan de muur - a website which facilitates direct purchase of prints of (a subset of) my work
