Having taken several first photos of my daughter on a day out, I was very surprised when looking at them on screen and zooming in, I seem to see a kind of black dirt which on further zooming turned out to be discoloured speckles randomly distributed over the picture.

I've now seen that the same effect occurs regardless of lens but most pictures are shot at 800iso which is not especially fast for this camera. Going back to pics from my old D70s, there is no such effect on any of the hundreds of photos which I looked through and in fact I have never seen this effect before.

Frankly I am very disappointed and I hope very much that it is a fault with this particular camera as I very often get the photos printed off at 25" and more. With the D70s they look great but I can see even on screen with these D300 pics at that size - and even smaller, there is already a sense that there is some dirt on the image.

Has any one any ideas. I'm really not sure what "artefacts" look like. Can anyone point me somewhere which explains and illustrates them.

I should add that the file was set to JPEG - 4288x2848 lossless compression
