I just want the weak of heart to know that cleaning the CCD of your D100 isn't really all that hard. I carefully followed the directions in the manual (yes, I bought the EH-5 adapter) and all went smoothly. I did the work while standing on a tile floor and actually brushed myself off with a damp cloth to avoid any static electricity.
I knew there was one really large particle causing a shadow and one or two smaller ones. When I opened the camera, I could see the largest ones and I blew them away with my trusty blue baby aspirator (1.79 at a discount store). I bought it just for this purpose. (No, it's not been in any baby noses.)
Just to record my cleaning operation, I took a photo of a white board at f -16 before and after the cleaning. I also shot the white board at f 2.8 after the cleaning. I applied photoshop 'autolevels' to all photos to make the dust really show up. (See attached) It seems to be the consensus that one should not worry about small particles because they rarely show in a photo. I know the opinions vary on this. For now, I do not feel the need to actually TOUCH the CCD. Perhaps in the future I will need to do a more thorough cleaning, but for now, I'm quite happy with the results and just wanted to encourage those who may be nervous about doing this.
