Photo Forum / Digital Photography / DSLR Cameras / December 2005Cleaned my Sensor (D70)
I finally decided to clean my sensor (D70). There was one particularly dark dust spot that I found very obtrusive. I had the camera in at Nikon shortly after I first got it, and not only is the $80 charge not acceptable, but there's the drive(s) to Mississauga and the fact that I'd be camera-less until I got it back. I read the articles, especially the one at http://www.prime-junta.net/pont/How_to/a_Brush_Your_Sensor/a_Brush_Your_Sensor.html and followed the procedure pretty accurately. Worked great! I still notice some minor spots if I blow up a frame, but they're light, somewhat translucent and quite acceptable. Next time I'll try to do a better "before" and "after" picture, but I took a few macro shots of the brush. They're at http://faczen.smugmug.com/gallery/1011875/1/48538949 if anyone's interested. -- Reply via the web portal at www.faczen.com or email usenet at firstaidco dot ca Why did you not try blowing it first? Just curious. Because everything I read said not to blow on it. Your breath contains moisture (and you'll probably spit on it), canned air is too strong, a squeeze bulb will just blow the dust around. If you blow air through a nylon brush (I used a bicycle pump), you create a static charge which attracts the dust away from the sensor. BTW I bought the brush at Loomis & Toles (an art supply store) for $12. Visible Dust wants $109 for the same brush. > Because everything I read said not to blow on it.

Those that come with ear-wax kits work well (don't use them after cleaning your ears with them ;>)). As to blowing the dust around, if it is removed from the sensor how long will it take to migrate back there? A puff or two from a clean syringe is my starting point and has worked well to date. Cheers. That's the purpose of the static charge on the brush. It attracts the dust. The article suggests cleaning inside the chamber behind the mirror at the same time to get rid of particles that might land on the sensor. To the other respondent: yes, I agree, I'm going to have to eventually use the wet method, but I'm holding off as long as I can. I've had the D70 for a year and shot probably 1000 frames/month. Not a lot of dust in all that time. > I finally decided to clean my sensor (D70). There was one particularly > dark dust spot that I found very obtrusive.

You'll probably find, while the brush method is good, you also need to occasionally use the wet method to get it spotless. _____ Slack |
