I have a Nikon D80. I love this camera but lately my resolution has been bad. When I upload the pics to my computer and zoom in there are tiny dots, like the photo is fuzzy. I usually fill a 4gb SD card and then transfer them to my external hard drive, then wipe the SD card clean and put it back in the camera. Is this ok to do? Could this be why my camera is suddenly taking crappy pics?
I have cleaned it thoroughly and I take very good care of it. Kinda stumped. Any advice would be appreciated. Thanks.

Without a sample we'd just be guessing, that could be a camera malfunction or dust on the sensor, dust on the lens, hot pixels, focus problems, impossible to say from the description.

That's fine, I've done that for years without any problems.
Do you have the problem with every lens or just one lens? Have you tried cleaning the lens contact points?
I only have the lens that came with it. I'm going to post a pic here. Hope you can see what I mean. It's a really bad picture of the moon lol. With tiny fuzzy light collored specs. It does it in day shots as well but easier to see at night.
aaahhhhhh! one picture was worth a thousand words.
thats digital chroma noise.... i bet a high iso or/and a long exposure was used ....thats one of the pitfalls of a small sensor camera as opposed to the more expensive full frame.
you might try a good noise reduction program like noise ninja or topaz has one thats good.

yep, you should do it only in camera, but thats not the issue, those speckled dots are chroma noise from long exposures... its the internal noise generated by the closeness of the pixels when they are crammed so tightly together on these small sensors...
the fx cameras have much larger sensors and the pixels are more spread out creating alot less of that colored speckled dot noise.
the d80 also had quite a bit when i tested it, i never bothered to test my d300 as i dont shoot at exposures long enough to be a problem.
Thanks for all the advice. When I got this camera it took great photos. There was no "noise" and my pictures were clear and crisp. I have tried everything with this thing and the tiny dots just wont go away.
Not sure why City Data deleted my moon pic but here's a pic I shot today at Notre Dame. Once again, the noise is there.
that photo is way to dark and under-exposed. that sky should be full of speckled dots...... couple that with a high iso speed and its a recipe for bad chroma noise..
we have had chroma noise that was in under-exposed pictures shot in broad daylight.
next time use your histogram and get everything off the left wasll and keep raising exposure compensation until the photo starts to hit the right wall.. if the photo is such that it hits both walls no matter what then try to capture the pixels that make up the subject and try to salvage the rest in post processing.
that scene is tough to expose in one shot ,if you try to brighten the sky enough you will prbley blow out the building. thats a perfect candidate for hdr or exposure fusion...

I shoot with a Nikon D80...only format your card in the camera! you may need a new card but before doing that go thru the settings on you camera to see if you haven't got like "long exposure" setting turned on or something in that area is not set right. Experience with this camera and gut feeling is you have a setting somewhere that got changed without knowing it.
