Dirt spot??
I've been noticing lately that there are 'spots' on all of my pictures....no matter what lens I'm using. I see no obvious dust or dirt and really have no idea what to do. Help?!!!
Example:
See it over there in the corner?!!! WTF?

Yah, it's on your sensor. If it was on your lens you'd never see it in the pictures except maybe as a soft spot.
You have to be careful when changing lenses, even if you are you'll still get dust. First thing to try is a bulb blower. The one I use is from when my daughter was a baby, available at any drug store for under $3.
Don't use spray air because it has chemicals in it and can ruin your sensor. The CO2 blasters are OK though because they're all air.

Chances are Ken's right. But if you are getting close to the end of the warranty date for your camera, it may be worth while getting the sensor checked out. Dead pixels are a downfall of digital cameras. And if you can get it replaced or fixed for free.... why not.
Re: Dirt spot??
When I say "be careful" when changing lenses this is what I mean.
First off. I always point my camera body down, it will lessen the chance that dust will get in (but not eliminate). I try to have the lens I am putting on ready before I unscrew the lens that is mounted. Take a look at the lens you are putting on and see if there's any dust on the rear element at all.
Try not to keep the inside exposed for too long, but don't rush either or you may make mistakes. Nothing worse than dropping a lens.

Also, be sure to turn the camera off while changing. When the sensor is on it could have a static charge that would attract dust.
I've cleaned my sensor twice in three years. Stupidly used a can of air and tilted it just a bit too much and got chemical all over the sensor. Some 99% iso alcohol and careful cleaning with a qtip fixed it nicely.
My nerves however....

Lastly, the best way to test for dust on the sensor is to shoot at a small aperture (f/16 - f/22) at a piece of paper or wall. Something without pattern, just a solid colour. Don't worry about a tripod if the small aperture makes your exposure time long as the dust is on the sensor and will be there whether you shake or not.

Went to Camera Craft since I thought maybe they would know the difference between a dead pixel and a dirt spot. The cleaned the sensor for me (because I'm too chicken to do it myself....) and now it's as good as new!! Pheww....
How it happened I have no idea, I just know that I've got to do some more research on the proper cleaning technique so that I can become comfortable enough to do it myself....

They clean sensors? When I brought my Canon, they told me it would cost me 140 to ship it to a Canon center to clean it! My dust only shows up in BIF shots, so I just clone the dust spots out.

Re: Dirt spot??
My thought exactly. When I went in they said they could ship it to Canon for a price or I could buy a $150 sensor cleaning kit.

Re: Dirt spot??
I guess they cleaned mine 'cause I looked sad and pathetic enough?! lol. Seeing as though Nurses don't make big bucks....
They didn't clean it clean it I suppose....they used the blower and a swab just like I would if I was brave enough. They also did say that if that didn't work they would have to send it to Nikon for 120$ and 3-4 weeks. Ouch.
