OK - I think I've come to terms with what dirt on the sensor looks like - dark circles with varying degrees of softness.
I am a little stumped by what I noticed on all of the shots I took the other night at a family get together - getting used to my new Nikkor 18-200 VR lens mounted on my D200. The shots were recorded on 2 different memory cards.
There are 2 small white shots in exactly the same position on every frame. As you run through all of the images in a slide show or with Irfanview, you'd almost think that it was on your screen because they are insuch perfect register.
Hoping someone has a clue what is causing this - and what the solution may be? Thanks
