I'm having a little trouble with some "blobs" appearing in my shots on my D100. They appear in the same position, no matter which lens I'm using, so the problem has to be on the CCD or mirror...? How do I clean this? Here's an example of what I'm talking about (with the "blobs" circled in gray):
I'll appreciate your advice! |

I would probably take it to a professional at you local camera store. I'm not sure I would trust myself to clean it. Especially if it is on the inside of the camera. Someone else with the same camera may have better advise than I do though.

The main advice I've heard is to NOT use those compressed air canisters. They tend to significantly cool whatever they're aiming at, which prolly won't be good for the sensor.
I might try carefully using a "squeeze" type blower, to see if you can get it off. If that didn't work I'd take it to a pro. |

Alan!...whatever you do, do not, under any circumstances, for whatever reason, not even if you have a gun pointed to your head, use compressed air (the kind they use for computer dust removal) when you clean this. It will kill the CCD.
Get a air bulb...and get the power adapter. When the shutter opens, exposing the CCD, use the bulb to blow that crap off the CCD. If that don't work...spend the $$$ and get a professional cleaning.
Dont try it!....Dont even think about trying it!...

| If possible, lock the mirror. I know the D30 allows you to do that, not sure about the D100. If so, then use an air bulb to clean the CCD. Never used compressed air it will damage the CCD. If all else fails get the pros to clean it. |

D100 has a mirror lock-up feature as well. Has to be powered by the adapor though.

Check //www.luminous-landscape.com. They put an ccd/cmos lens cleaning article up yesterday.

Just as a follow-up, I did go in and tinker with the camera last night with some success. I read in the manual that you should plug the AC adapter into the wall, and choose "CCD Cleaning" from the on-screen menu so that the mirror would flip down to expose the low-pass filter. That's all good & well, except I don't have the optional AC adapter...
But I learned that you can set the camera on manual, choose a 30-second exposure and click the shutter to open it for that amount of time. That gave me enough time to use a blower to shoot air in there to dislodge the dust.
For the most part it seemed to work well. There are still a few little blobs remaining, but I seemed to have nabbed the most annoying ones. I may repeat the process again after I take a few more shots to see how annoying the remaining ones are.
Thanks again for the URLs and advice -- all very helpful! |
