Found this while strolling around the The Nut Tree in Vacaville.
Manual: Read page 42 and 43 "Cleaning the Cmos sensor"
Images: Just started reading Joe Mcnally's book "Hot shoes Diaries" so I viewed images on his website. I had the pleasure of attending his workshop this year. He's a super nice guy and a great sense of humor. The workshop was awesome. He shared a lot of info on shooting with one light, using reflectors and strobes.
