Need Help Please -- Canon 20D is showing wierd spots on the image

[jimchapin468]

My canon 20D is showing wierd spots on the screen when I view the pictures. Is the sensor dirty or what? IF so how do I clean it. Thanks for your help Jimmy

PS: This is a 100% crop....

They look like finger marks.

Looks like dirt, do a search and you should find plenty of threads here explaining different ways on how to clean your sensor.

It's dirt on your sensor - stop your lens down to F22 or F32 and you'll see it more clearly rather than as unfocused blobs. I clean my sensor using this system (http://www.pbase.com/copperhill/ccd_cleaning).

Yep - dust on the sensor. Use the easy Canon method first. If that doesn't work, follow Tim's link. I've used the same Copperhill method that Tim used, and only needed to do it once. Every speck of dust I've had since has been removable with a simple rocket blower.

Sensor dust....classic 20D issue. I blew mine out with a hurricane bulb....no problem, no full out sensor clean...thank God...I wasn't looking forward to it...lol.

Sensor dust....classic 20D issue.

It's an issue with any DSLR, if you remove the lense, dust can get in. I use a bulb to clean as well, just as the manual describes.

Here's a good guide to cleaning dust off your sensor:

I grabbed some of those sensor swiped that are insanely over prices, i keep two in my bag at all times, damn expensive but damn handy...makes cleaning super simple and fast.
Ive done the whole wendy's knife before, pretty easy, but i dont like carrying solution, clothes and a cut off plastic knife around

That is dust on the sensor........I have a few specks and haven't bothered cleaning the sensor yet but just clone them out of any shots where they are noticable.
