I have the dreaded spots on my sensor, I used my blower brush to try to get them off with no luck. Anyone have a quick and easy trick to remove the spots?

Thanks, Troy

One way is to use the "dust delete" function. See page 149 of the manual.

Here's a good introduction to sensor cleaning: http://cleaningdigital​cameras.com/ (external link)

And here's a good tutorial: http://www.copperhilli​mages.com/index.php?pr​=tutorials (external link)

I use the Copperhill kit for wet cleaning, as do lots of other POTNers.

I sent it off to canon to have it cleaned. I am defenitly going to purchase that swab kit.

I noticed on my camera the mirror was clean , the plastic looking cloudy part was what had the dust spots on it just above the mirror? I guess that part is called the sensor?

The focusing screen?

The image sensor sits behind the shutter, which sits behind the mirror.

A quick way to check for sensor dust is to take a shot of a clear sky using an aperture of f/11 (or f/16). If you see spots in the image that's sensor dust, otherwise dust you are seeing in your chamber is on something that won't affect your images.

The only way to see physical dust on the sensor is by having the mirror up and the shutter open, which is typically done by using the "Manual Sensor Clean" function. And, since very small particles of dust can show up as ugly spots, people do use various ways of lightening and magnifying their view of the sensor.

And, I'm one who strongly advises that you get wet-cleaning fluid and swabs and learn to use them, carefully but confidently!

I bought the Copper hill stuff. Once I put a few more months of use on my camera I will take a whack at sensor cleaning.

I use a cheap and very effective method.

Snap photo of wall @ F/10 100ISO adding in a little motion blur so as to not confuse a blemish on the wall with actual sensor dust.

Open camera up with opening facing down. Air spray the surface with a rocket blower.

Take a nikon lens pen brush (some might say it is too abrasive) - and give the brush a few shots of canned air spray (get any potential dust out)

Lightly brush from one end of the sensor to the other. Repeat a second time to make sure you got the whole surface.

Shoot the sensor with a few more sprays of Rocket Air blower.

Take another tethered image to your software and inspect on screen. I find this method works in one attempt whereas other methods have had me repeating over and over again. It really works wonders...
