Hello out there.

I just read through a couple of threads regarding the removal of dust on your CCD.
  • First of all I'd like to mention that dust just s* x.
  • Second of all I'd like to encourage all other readers here to read what is posted here. I first removed the dust on my sensor on my own way, without knowing, that it could not be a good way. (In particular I used a bit of Hama Anti Dust spray. Hopefully I did not harm my cam...) Than I found out that this is not recommended. Darn! next time I take it to the nikon service point, and not gonna do it myself.
  • But there is a question I still have: The common recommendation for the removal of dust is to use a bulb. Now I am a stupid german, and I do not have any clue what such blub would look like. Mý dictionary says that a bulb is that thing inside your lamp which actually emits the light, but that cannot be ment. So: Anyone here to explain me what that is??
  • Finally: Any recommendations on how to remove the traces of dust from the pictures ?? (JPEGs) I tried the copy stamp with good results... Is there any better way?
Thanks for reading, and thanks even more for any advice...

Nevermind, I thought you meant the bulb-like blower.
"Bulb" is the shutter setting to keep it open to clean
the acutal CCD instead of the anti-alias filter.
 
Hello

First of all: thanks for the reply!

no no... it looks like this is exactly what I was looking for.

Isnt the AA filter in front of the CCD when you take a picture? If you choose the bulb mode to take long time exposures (that's what you are4 talking about?!) it should be there too? no?

confused

I wish there was some more info / tool recommendation in the manual...

"Bulb" setting means the mirror lifts up to expose your sensor (which is covered with AA filter). You can then clean it using the right tools.

Hello.

Ok. now I am totally confused. AFAIK there is an AA Filter in front of the CCD. This one can be cleaned - according to the manual - by using the inspection mode for the mirror. From your suggestions I find that the same can be done by doing a long tim exposure (without the lens attached.) . Is this correct?

Is there any chance that dust gets beween the AA-Filter and the CCD?

What would I do in this case?

confused

Hopefully I did not harm my cam.. How can I find out if the AA Filter is broken, or would I see this on the first look?

Thanks again

DO NOT USE BULB MODE TO CLEAN YOUR CAMERA!

The CCD is charged when in bulb mode, and the charge of it will attract dust. You DO NOT want to clean the cam in bulb mode. There is an option in setup called "Mirror Lock Up", this will bring the mirror up without charging the CCD. This is what should be used to clean the CCD.

The bulb is for the name of the "bulb brush".

Yes, there is a glass AA filter in front of the CCD. The risk of using compressed air on the AA filter isn't breaking it -- it's getting more gunk on it from the propellant of the compressed air.

Hello

Thanks for this reply. This really confirmed what I by now have learned from

. I just wonder why there was the suggestion to use the bulb mode for cleaning the CCD if there is a mirror lockup function. Or do not all cams have this.?

Anyhow: I used compressed gas (not really air, as it consists of 40% propane/butane), and removed some dust with it. I will not do that again, as I now know that it is not a good idea.

Do you know why one should use the power adapter? Is that because of static charge stuff? Or is it just because the battery could run low while the mirror is open, and the cam would not like that?

Darn! this issue really gives me some trouble, as I still am scared of cleaning my ccd by swabbing (plus I have to order the pec pads from overseas or so since I live in germany).

I think I will pay a visit to the nikon service point (which is fortunatly located about 2 km from my place) tomorrow and see what they tell me. (I'm especially excited on how much they would charge for a CCD cleaning.)

:-( I'll be on vacation for four weeks later this year. I cannot carry the nikon service point with me during taht time. damn it.

Your reasoning is correct, it's to prevent a battery outage while cleaning. If the battery were to fail, the mirror would slap back down and you could snap off your cleaning stick or damage the mirror/other internals.

...for all your input. I feel much better now and do no longer have the feeling of having eventually harmed my cam.

Still I have to find a way to deal with dust while I am on my long vacation.

You can also get something similar at your drug store. You use it to clean a baby's runny nose, among other things.

Haven't met a stupid German yet. Must be my luck.

I do believe when they say a bulb they mean the air-puff, turkey baster-like device and not the bulb setting in the camera.

The D70 has a separte mirror lock for dust removal. Last thing you want is the mirror to come slapping down on the bulb because you pressed the release button.

To remove dust in photos, I use the Healing Brush Tool in Photoshop 7 & CS.

It does a better job in most circumstances that the Stamp Tool. I also zoom in about 400 percent so I really see the dust.

Works fairly well for film, not sure how it will work for the sensor. Costs about $10 USD.

Canned air works far better for film than the bulb.
