So, I've got some dust on my 400D's sensor, I noticed it when I was out at Cumberland Falls shooting around dusk using I think F29 at 2" trying to smooth the falls without so darn much light coming in. I noticed the dust right away. Made me sort of angry... I don't know how to fix it or where to take it, I don't want to send to canon as I've heard that it is exorbitant cost. I read about the rocket blowers or even canned air but I don't know if I want to risk the canned air on my sensor. I know that its actually on the sensor and not the mirror as I carefully inspected it with lots of light and a magnifying glass. I don't really do many landscapes, when the waterfall is frozen (1/500) the dust is not visible but when smoothed it is, I did some test shots in my white box, as I do a lot of macro and portrait, I really just need some help. If anyone knows of any photography stores that would have the proper cleaning stuff on hand around the Cincinnati, Oh area that would be great!! My only other thought was to take it to an A/V repair and see if I could get a quote or even if they can work on it.
This is in my white box with the white balance way off, but it shows the spots the best.
