A mix of places I visit for help, advice, inspiration…
http://www.filmwasters.com/ – great home for film based photographers to chat and share work, info and news
http://www.alternativephotography.com/wp/ – web resource for all things alternative – cyanotypes, liquid light, etc
http://www.ilfordphoto.com/home.asp – probably the most useful, straight talking resource for developing film and prints. Not exclusive to Ilford product users as smuch of it is universal knowledge, although I think Ilford do make the best materials
http://www.digitaltruth.com/ – mostly film related funnily enough, including the Massive Development Chart which is superb and now avaialble as an iPhone app
http://unblinkingeye.com/ – resource info, artist galleries, alternative processes
