I have a Nikon D40 and I am noticing a small "shadow" in all of my pitctures which looks like there is some dust on my lens. I have cleaned all of the optics and I still see it in every photo.

Any advice on diagnosing or repairing myself?

Is this something I would go to a camera store and get "rapeaired", or should I just go buy a new one?

It sounds as if you may have some dust/spot on the sensor, but since you don't show any examples, it is only a guess. Try blowing it off with a blower or cleaning the sensor.

A popular cleaning technique can be found here (http://www.copperhillimages.com/index.php?pr=tutorials).

A local camera shop should have the supplies you would need.

This is in every shot. I cant see the dust or a smudge on the sensor.

Do you have more than 1 lens. If not, go to a camera shop and try some other lenses.

If the spot is still there with other lenses, I would try cleaning the sensor. If it is not there with other lenses, there may be something on the internal optics of your lens.

Is my sensor this plastic or the part above or behind?

You do not actually clean the sensor, but actually the filter covering the sensor. Do not try to remove the cover over the sensor.

Is your mirror in the locked up position? It looks as if your photo is of the mirror.

There is a little mirror behind what you see there.

Its attached to the back and is on its own articulating, spring loaded, mechanism.

Behind that is the shutter.

Above that is a ribbed plastic screen.

So was your camera in the mirror lock-up position as described in the owners manual page I attached to a previous post when you took the photo? It must be in this position for the cleaning, or to be able to see the sensor/filter assembly.

I ask this because your photo looks as if the mirror is not in this position.

Ray Schnoor - you the man! I locked the mirror up and I found dust! I blew it out with compressed air and I am now not buying a new D90!



Ray - if you need help managing a trading floor or correcting car paint. I'm here for you!

Glad I could help, but you would have loved the D90.

I may still buy it, triplets on the way. Can have enough cameras for that!

Is it safe to clean that mirror back there with something other than compressed air?

Its filthy!

It may look dirty, but unless there are spots showing up during normal shooting, I wouldn't worry about it.

If there are spots, you can use a method described in the following location with a swab. http://www.copperhillimages.com/index.php?pr=tutorials

I went for it. Made it spotless using your suggestion.
