Bath -- Once a year whether I need it or not.

Recommended Posts

Ok so I've had the D60 for a little over a year and had started to notice some imperfections in the images. At first I was pretty sure it was just dirt on the lenses and whatnot, but a little testing proved I needed a sensor cleaning.

Damn! Well, actually, it wasn't too horrible to do myself.

The test you want to do to determine this is to take the lens off the camera, put the camera in manual mode, 1/500th of a second or thereabouts and fire off a shot at a light lightbulb about 5 to 10 feet away.

This will give you a photo like 5359. If you look closely, you can see some slightly dark splotches on the image. That's light filtering around dust on the imager. You can see it really well if you then take that image into PhotoShop and do an Auto Level adjustment. Take a look at 5359autoLevel and you'll see what I mean. Yuck. That's a heck of a lot of noise buried in my images.

After cleaning the sensor I did the same tests and while not -exactly- perfect, I think it's pretty acceptable.

Better yet, by doing the cleaning myself, I got the supplies to do it several more times for the cost of sending my camera in once.

If you're not handy with stuff, you might still want to consider sending your camera in, but it's not really all that hard to do it yourself either.

Wow. Amazing examples of before and after. You said that you now have all of the supplies for cleaning the sensor. Could you give a little more detailed information on what supplies you have / used for cleaning?

Thanks.

Besides following the directions in the camera manual on how to lock up the mirror and lock open the shutter, you'll also need two other consumables; cleaning fluid and swabs.

The cleaning fluid of choice, according to the guys over at Calumet Photo is "Eclipse" from Photographic Solutions. http://www.photosol.com About $8 per bottle and should last quite awhile as long as you never leave the cap off. Eclipse comes with a package of ten cleaning pads you can use for lenses but not for the image sensor of your digital camera.

Photographic Solutions sells a separate "Sensor Swab" pack of 12 swabs specifically designed for image sensors and these cost (take a deep breath) $48 per 12 pack.

Ready the camera, ready the swab by putting a couple of drops of fluid on it, lock up the mirror, open the shutter, 1 wipe in 1 direction, flip the swab over and wipe again, shut down the shutter and mirror and take a test photo. If you don't like the results, repeat with a NEW SWAB. Took me 4 swabs to get the results I thought were acceptable.

Since there is a real danger of damaging the sensor with poorly manufactured swabs, don't be stupid and try to get away with using the swabs that come with the fluid or, God forbid, a Q-tip.

Still, all in all, this if FAR less expensive than sending your camera in to the shop and having them do it.

Sounds mildly annoying Paul, it would be a shame to spoil a great photo opportunity for the sake of a little dust..... So, putting engineer's hat on and approaching the issue from a different angle, is there any recommended way to avoid the dust getting in? I used to tape up my old Hi8 maybe something similar required here?

All the dust turns to mud pretty quickly over here Deuce!;)

Just thinking out loud, with my 'keep it simple head' on, avoidance being better than the cure kinda thang.
I was really blown away by those expensive q-tips!:)

I too believe in avoidance... but in CA (where Q and Duece jump), like in AZ, dust is a fact of life, short of buliding a clean room on the DZ where you can change your lens... Unfortunately the problem exisits here in TX too... I find my camera is need of cleaning, just been too lazy to do it.

I think you're probably protected pretty well from fairly large dust particles -- those that would be visible to the naked eye. These are extremely fine dust particles on the order of say, smoke from a cigarette, so I think that over the course of a year or so, there's probably nothing you can really do to prevent them from contaminating the imager -- unless of course you keep the camera in a clean room and never take it out to play with you.

I'm thinking that jumping, with all of the air pressure changes that go on, probably will vent and leak enough air so as to make anything short of a totally air tight seal a fruitless exercise. I also doubt that you could get an air tight seal since that's not the way the camera was designed in the first place. Lastly, any kind of gaff tape around the lens might acutally make things worse as air trys to vent and leak through it. You might capture some particles on one side, but shed particles on the other.

These were Canon lenses.

Canon cameras, historically, have a somewhat looser connection than say, Nikon, but I don't really think thats the main issue anyway. I think it's just a matter of time before you'll need to clean the sensor no matter what you do.

One thing on the digital note, there are a few advances out there in technology, that will probably make itsway into other cameras.

Unfortunately, I cant remember which cameras have these qualities..

1) Environmentally sealed units (I think the new 4/3 ('four-thirds') camera from Oly.) that have o-rings that will seal out dust better. My only worry is condensation though..

You still have the 'lens change' problem of dust getting in then, but for a lot of people it who only use one lens, it will help out a bunch.

2) There is one or two digitals out there with CCD/CMOS cleaners built in. I think the most advanced one is a 'high frequency vibration' clean mode, that basically vibrates the dust off the sensor.

I seem to vaguely remember the Nikon D1H that I was using for a while having a blurb about an electro-static accessory that charges the dust particles, and the differential pulls them off the sensor.

I have no idea whether touching the sensor will have any long term effect, but I guess part of me feels that if mfgs make 'no touch solutions', then they really dont want you to touch them. But, that is probably just to reduce the risk of joe shmo beating the sensor with a regular qtip.

Funny thing, B&H wouldn't ship the solution. Store only.

So I got it from Calumet, who didn't have a problem shipping the stuff.

Q, I have photoshop elements. When I click the drop down menu for "enhance" and then click "auto levels" I get virtually no change in the image. Is there more to generating that enhanced image? Something I can't do with just the photoshop elements program?

Photoshop Elements . . . hmmm . . . I supposes y'all could go into the manual level adjustments and try to expand the contrast by manually if you -can- do that in Elements.

I don't think I have a copy of Elements handy to give it a shot.

Took Elements off my computer but when I did have it up and running, it -did- allow you to do manual adjustments of this type to the image.
