Sensor Cleaning

[leon]

Although my Pentax IstD dose have some dust spots, that really dosn't effect the final image that much, would it be wiser to leave it alone, of risk doing more damage to the sensor.
What do other digital users do.
I have heard that it is easy if you know how, but if you do it wrong you don't get a second chance.

Hi Leon

Sensor cleaning can be a problem if done incorrectly. If you do a google search you should be able to find a variety of products that will help.

I noticed that I had a couple of specks on my sensor a while back. All I did was to use my jumbo blower bulb to blow air across the sensor of my 300D and luckily it removed the problem.

Of course the other way to deal with dust motes is to take flats frames and apply them to your subframes. this usually fixes the problem too.

Cheers

Don't forget gumption either Gama!

I have bought this system and it works, blowing the brush with dry compressed can of air charges the brush first then you gently brush in one direction only once, then "clean" the brush again with another blast of air, then repeat if needed. 99.7 % of the time this is all I have to do. Its very simple and the brush is specifically made for this purpose. PLease note to Gama, i use a giotto rocket blower first to remove what I can, and sometimes I don't need to do this.

How is the Nikon after the "clean" gama?

I didnt touch the Nikon Sensor, cause if it has any previous problems, they may blame me for it. I didnt want to take any chance with a $2800 camera that isnt mine. Im glad its gone back and no nasty email or phone call telling me i buggered it.
My D200 is on order, as they are on back order.. So im expecting it in June/July shipment. The D200's are sold out on back order till then.

I do find however that if the wire brush does have a problem with some stubborn ones, a quick heating with an Oxy torch on the sensor will loosen the spot, then a quick scrape with a chiesel will get rid of it.

And diamond dust works well to get rid of the stubborn stains too...

i know it is a toucam and probably different to these bigger more expensive cameras, but i have been using isopropyl and a cotton bud and it seems to work well

Asimov is my man for cleaning sensors.

He can remove any number of dust bunnies, might take a while but boy is he careful.

Doesn't use angle grinder or any of his workplace tools. He could have been a eye surgeon.

Just distilled water, cotton buds and blower.

hopefully noone here is thinking of cleaning their own retinas...
I'm having an experienced CCD photographer who's successfully cleaned his sensor repeatedly just use the air blower to try and dislodge a speck in my 20Da tomorrow....and I might not get any sleep worrying about that!
I'll let you know how that goes 9not the sleepless night bit, the cleaning bit)
