Photography Question

Dirty Chip


I've got a D-70 and I have noticed some dust specks on some of my photographs when I blow them up on my computer. It only seems to happen when the lens is closed down all the way and not at the larger apperatures. I'm sure it's on the chip because I get the same effect on two other lenses. I bought some sensor swabs to clean it and also used some air on it, but have had no luck getting it cleaned off. I just seem to be moving the dust specks around on the sensor. Is there anything else I can do myself to eliminate this problem, or do I need to seek professional help on this one? Any help is appreciated, thanks.

  Hi Frank - there is a similar discussion currently happening in a question titled: cleaning a digital sensor. You might want to read that one.

What I can tell you is that I had the same issue and was convinced that I had to take the camera to the shop and pay someone else to do the cleaning. Then I read the answers to the above question and saw where Charlie Borland (one of the instructors here) wrote in about the Eclipse system. Being new to digital I was a little intimidated about the idea of cleaning my sensor myself, but I found that this kit makes it easy and relatively hazard free. Prior to using it I had tried cleaning the sensor using an air blower – it didn’t do enough, although you will want to first use the blower to remove any surface dust. The kit consists of a specially designed swab (you select it according to your camera) & the special fluid called Eclipse along with cleaning pads. You use the pads on lenses, not the sensor. The kit includes clear instructions. Also, everything I read strongly warns against using “canned air” anywhere near the sensor – as you probably already know, canned air sometimes expels moisture with the air and this can harm the sensor. Just this morning I used this kit to clean the digital sensor on my camera and it took all of 5 minutes and was not nearly as hard as I feared. My test shot showed no signs of dust. Hope this helps.

Frank Goodin   Thanks Irene. I will give this cleaning kit a try and see what I can do myself instead of taing it to the shop. It sounds a little intimidating but I'ld like to know I can do this type of maintainence my self instead of having down time at the shop.
