Are you shooting with a small aperture? That'll do it.

Yes, I shoot mostly f.22 as I do landscapes...can't compromise on that.

Quote: I only removed lens to give a blow of air to see if anything would be removed.

So you blow with your mouth?

The camera has an integrated dust reduction system, you only have one lens and you have even had it professionally cleaned once already ?

Are you quite sure its dust particles.

Quote: If there are not too many dust, then I wouldn't worry too much about it as they can be removed afterwards easily.
You can always clean it yourself using artic butterfly.
On a side note, you don't really need f22 just because you shoot landscape. What lens are you using?

I get my prints done by Digital Lab and the dots are very visible. I use the 18-105.

Can't you upload a photo to show us?

Well, you need to clone them off first in photoshop or something like that before sending the photos to the lab.

First up as " Cole " has said, There is no reason to always use f/22 for landscapes, Apart from anything else you will encounter " Refraction " effects, That will almost certainly soften an image more than using a larger aperture......

Read up on " Refraction " and you will see what I mean......

Next, Some camera makers claim that a certain amount of what appears to be dust, Can be the result of internal parts " Running In " How relevant that is I have no idea, But on the face of it, Its a possibility as well as an excuse.....!!!

Dust is hardly an issue when you have access to Nikon Software or Adobe Software, They both offer various tools for removing dust spots.....

If your using a blower, Especially a cheap one, Chances are your blowing more dust into the camera, Than your blowing out of the camera........!!!!!!!!

WHY, Because unless the blower is fitted with a filter on the intake valve, Then as it re-inflates for the next blow, It draws dust particles in from your surroundings..... As fast as the air passes through it, So to do the dust particles, And unlike the odd bit of dust that just finds its way in, Your now blowing it in under pressure, Making the situation much worse.....

So if you must use a blower buy a decent one that has filtered intake and exhaust valves, Something like the " Rocket Air Blower " ......

Something else to be wary of with cheapo blowers is the material they are made from, Those ones with brushes on for example carry an awful lot of dust in the brush, Look at one under a microscope, You will be horrified.......

So take on board what I and others have said, Stop worrying about dust, Check your images very carefully before sending to printers......!!!!!!

I have a 6 year old D70, Its never been cleaned ever, It has had an occasional blow with a Rocket Air, I do not have issues with dust on that camera or the others ( D200/D700).
