Had a bit of an accident with my D40 while its body was wide open and ended up with a REALLY dirty sensor. I had heard about the great job that the Lenspen Sensor Klean does... and gave it a go. Overpayed for it I'm sure (15 quid) but heres the results:
100 % cropped, different colours due to different backgrounds used.
