hehe - welcome to digital SLR photography

if you want a shock, take a picture of a plain light coloured (or even white) surface at the highest f-number you have on your lens - doesnt matter if you take a blurry picture or not, infact sometimes it helps.  You will see a lot more of those little dots

"In every colour, there's the light.
In every stone sleeps a crystal.
Remember the Shaman, when he used to say:
Man is the dream of the Dolphin"
