Unhappy HELP Please Black Spots

I don't know if this is the right place to ask for assistance but I'm sure it will be moved to the right place if required I have a canon 350d (rebelxt) and I have suddenly developed black spots on my photos I cannot see these spots through the lens therefore i am wondering if this is a problem with the sensor it is very very rare i have removed my lens from the body the only things i have tried is cleaning the lens and used a rubber blower to blow the sensor here is a photo with said spots on mainly in the top left corner please view large thanks yours in anticipation

Im probably not the best person to answer, but it looks like dust on the sensor/lens to me... You could have another try with the blower, or I think you can get special sensor cleaning kits... hopefully someone else with more knowledge will have some ideas....

Yep, it will probably be moved, but it is a dirty sensor. If you need help on the cleaning PM me.

There should be a clean setting on the camera. It will lock the mirror up so you can blow the dust off the sensor.Turn the camera upside down (lens opening facing down) and use the blower several times to clean the dust off. The camera battery must have a full charge.
DO NOT TOUCH THE SENSOR WITH THE BLOWER
Good luck

It is dust on the sensor. You can prove it by taking several shots a different f-stops they will get sharper at one small f-stop and become almos invisible at large f-stop.

As the spots are clumped in corners try your blower again and blow off sensor in all areas

Yes Elmo I've checked the data on two different shots and the one with a large f stop is almost invisable

Be careful with the blower that you don't accidentaly blow in more dirt.

It could still be the lens, I have 3 - 4 spots like this on mine that were there from the day I bought it. They are not on the sensor as it dosen't appear on my other lens yet they will not dissapear despite cleaning both ends of the lens many times over.

Blackdog 71, I've had the same thing like you do but finally got my camera clean like a sharp images without the dust. My suggestion would be for you to clean the camera with Sensor Scope. It does a amazing thing to get rid of all the dust. I know it cost a bucks but its worth it. Or you can do another way DUST-AID DSLR Camera Sensor Cleaner along the Eclipse Optic Cleaning System. You have to read your manual book before you do any futhure.

I've heard good things about the lenspen sensor klear. You might want to check it out. It sounds a bit easier to deal with than pecpads and cleaning solutions.
