Hi again,

I discovered that Nikon offers a dust correction system called "Image
Dust Off" coupled with the Nikon Capture 4 software.
You take a reference picture from the camera (you have to take the
picture at 10 cm from a white screen) and it serves as a reference for
eliminating the dust on all the subsequent pictures.
In order to do that, you have to buy the Nikon Capture 4 software
(unfortunately, you have to buy it so I just tried it).
Another constraint is the picture has to be stored as a raw NEF
picture (Nikon picture format) in order to be processable by Nikon
Capture.

The results were quite good when I applied it on my dust test picture.

AFTER DUST OFF: http://webpollux.free.fr/public/6a3ce1522dcb5d6e8de5b91450689adc/after_image_dust_off.jpg

But the results were really bad when I applied it to my cushion's
picture as you can see below:

Consequenlty, I won't buy the Nikon software and wait a few days for
receiving my sensor cleaning kit (a physical action is always better
than a software one)
I have no idea why my results were so bad for the second test whereas
they were good for the first one => I suppose that it is due to the
picture complexity in the 2nd case.
