i have noticed many times now that there is something that appears to be on my camera sensor(nikon d40),i get 2/3 bits of what look like fine thread showing up on pictures,it isn't always noticeable if the picture has lots going on in it but when the subject matter is plain it is really obvious,any tips on what i can do to shift it,i'm pretty sure it isn't the lens as it happens with both lenses i have
I would recommend googling this (how to clean nikon sensor d40 will give you lots of results) and even checking YouTube. I have not had to clean the sensor on my D5000 yet but I do know these things:
It can be done yourself with extreme care and a fully charged camera battery - if the battery dies mid-cleaning you can end up damaging the shutter which is an expensive repair.
DO NOT use compressed air! It can blow stuff into the body of the camera and cause damage that may not be able to be repaired.
When in doubt, take it in to a shop for a cleaning. It is not that expensive to have done! =)
you should get a rocket blower then you just:
-remove the lens
-hold the body upside down so the screen is on top
-then just squeeze the blower and any loose dust/stuff should come off
this is the safest option as it doest damage the sensor or leave any wet streaks/marks.
I have not tried this as I dont have a blower but i am going to buy one.
@sallycheese The cost for a professional cleaning seems to run about $50 around here too and that is far more reasonable than having to replace the body. Personally, I won't try and clean it myself. I am sure it can be done and with practice it is not hard but I can't afford to replace my camera if I screw up so... =) Good luck! Let us know how it goes!
@rayreeder yeah the threads are always in the same place @ronphotography i wish i could afford a new camera lol, although i do really like this one,it's light and it isn't black which is also a bonus ;)

Dust normally shows up at small apertures.

Here has some ideas for seeing what dust is on the sensor.

Are the threads always in the same place?
If not it may be possible to use the rocket to blow them off.
As has been said do not use compressed air. And do not be tempted to blow with your breath as this contains moisture and bacteria.
In most cameras you are cleaning a filter that is over the sensor and not the sensor itself, although of course you do not want to damage it.
