Some of my favourite places on the 'net' to discover and educate are:

Google the ultimate search engine

The Luminous Landscape, the web's most comprehensive site devoted to the art of landscape, nature and documentary photography...

fredmiranda.com a great place to view and learn about photography.

VisibleDust is a Canadian company devoted to developing some of the best solutions
for cleaning the sensor and inside of digital SLR cameras.

Doug Gilbert Fine Art Photography
Another fellow artist whom I met during the Victoria Tall Ships 2005 festival.
I admire his work and feel you too may enjoy it.

Autopano Pro is one of my favourite and invaluable tools for creating panoramas.

Canon Camera Museum
Is a look at yesterdays and todays technology behind the art of photography with Canon.

 

Please note that these sites are not listed in any paticular order but I have listed them
because I either feel they are of some educational or artistic merit.
