forget the spots, that is the oddest shade of white I have ever seen.
those sopts seem to be more dirt than dust. from my own experience, dust spots seem to be fuzzy and often look like a light smudge. these spots are pinpoint sharp. please correct me if I am wrong!

Nothing wrong with compressed air!
It works a treat!

Simon - did you take that with a very small f-number? When I have done a test image using f-22 stuff still shows up, even immediately after I have cleaned the sensor. A colleague from here suggested to me that maybe it was impractical to hope that everything could be removed - maybe he's right.

I have no idea how the hell you could absorb such amount of microorganisms inside your sensor...Man you have to think where and what have you done when changing lenses. It was a windy and dusty day? How you change lenses?
I normally put the camera down when remove and insert a lens. In one year I had to clean once my sensor. Of course got some dust but Photoshop do the job...
All the best

This is my first outing with the 20D, and there are spots everywhere, but with some layer techniques and equalising the image, they are easy to remove. I am planning a cleaning though.

Cheers Chis , my old man had a compressed air gun so i will give it a blast of that to see if it improves.

I think Fergul is right there - it sounds like you are talking about the mirror. Easy to check that - it behaves like a mirror . Basically it doesn't matter if this is a bit mucky, as it will only affect the quality of the image you see through the viewfinder. But you can clean that with a good lens cloth if you want (gently).
