Look at the picture ... this occurs in all the pictures ... i took this one in the dark just so they are visible (blue dot in the middle and a white-gray one under it by a bit)

the image (http://img213.exs.cx/my.php?loc=img213&image=img125015zj.jpg)

the lens is fairly clean nothing that i can see
but under the outer lens (or glass if you want to call it) there is another lens which has some dust but i can't reach there to blow it off


Thank you

well i ran a few tests ... on jpgs and on raw files (converted to TIFF) the raw showed no dead pixels but alot of hot pixels ... however the jpgs had a lot of dead pixels but i think that has nothing to do it

Now what should i do? clearly the spots don't usualy change position (as far as i can see) but could it be the dirt (or dust) between the lenses?
