Dark Circles on prints

[Carol S]

I have large, dark circlular areas on my images---always in the same spot---too large for dust altho I have cleaned the sensors.

Anyone else have this problem?

Carol, I think you need to post a little more info or even a sample picture. How large are the circles? Are they always in the same place? Do things change when you have a different f-stop?

This link is to a picture posted on a different thread that shows what dust looks like - how does it compare to what you see?

Yes, that is what they look like---I thought that they were too large for dust! Do I need to get the camera cleaned by Canon or what do you suggest?

Thanks so much for the reply!!!

The best advice: http://www.pbase.com/copperhill/ccd_cleaning

... or do a search on the forum for 'cleaning sensor'

I've had my camera cleaned by Canon and had a go myself. Neither of us got perfect results!

There's lots of advice on cleaning on this forum (as Andy hints at) and it seems that the rubber spatula thingy is the way to go (Link on Andy's post). I've just bought one myself and am plucking up the courage to go in there!

Mostly, I've learned to live with a little bit of dust and when necessary, I edit them out with PS. When things get too bad, I'll have another go at cleaning.

Good luck.
