CMOS sensor cleaning...

[Redbird_xo]

Found this website that has step-by-step photo illustration. Thought I share this with my fellow Forums members. You don't need to install Chinese character font to view the pictures. The pictures are pretty much self-explanatory, so you don't really need the text explanation.

Do you think it will work?

Well, without the text explanation, what we can see has no big interest besides of seeing the way this lady attaches the lil' piece of kodak cleaning tissue onto the blade.
As we don't read chinese, could you tell us what is explained in the comments?

This is the standard cleaning reference:

I would strongly advise not to use a metal ruler or dry lens paper as suggested in the link above.

A METAL RULER?! I would NEVER use that on my sensor!!

I have the Copper Hill SensorSwipe, which Scott provided a link to. It has a soft rubber tip so it's impossible to scratch your sensor with it.

Thanks for the link, it serves as a warning to demonstrate how NOT to clean your sensor.... :rolleyes:

Wow, that's about the worst way to clean a sensor i've come across. Can someone who speaks the appropriate language email him and tell him about this thread/copperhill?

I'll take the garlic snow peas and shrimp.

In the web site, the guy mentioned to use plastic ruler, but at that time he couldn't find one, so he show the metal instead.

I looked closely on the Kodak package, and it says...a soft, lintless paper specially prepared for cleaning lenses, filter, and other highly polished glass surfaces...

The CMOS sensor doesn't quite fit any of the above material. Another caveat emptor thing, I guess.

There aren't too many details that you can't get from looking at the pictures. The line right below the last pic says, and I quote in translation "the above only shows Yesun has done such cleaning, we are not recommending readers to do the cleaning in the same way."

It's nothing more than a covering the behind kind of thing.

i don't think those are ladies' hands :-|

in addition to saying he only had the metal ruler, i think it's a question of available supplies as well as a cost savings for him over the cost of having it cleaned (with no guarantee that after paying for a cleaning, it would be clean). sure it's not a way any of us would go about cleaning our sensors, but i'm also guessing when he got his 300d (it's dated before the 300d came out...), people didn't necessarily have common knowledge of methods like copperhill. so you certainly have to respect him for making it available to people. just because it's on the net, doesn't mean it has to be 100% the best or only way. as he says, he's not recommending anyone else try it, but it's his way of getting it clean.

it also makes me wonder - what do 'authorised' Canon service guys use? i'm sure they're not using copperhill stuff. there are probably many different things they use, based on which country/state/etc. the centre is in, and whether Canon has published an 'official' document for them to follow.

I was reading through the copper hill link. They recommend cleaning your sensor every couple of weeks. Geez, that seems kind of extreme. Any comments?

Clean the sensor when it's dirty.

How to find out if there is dirt on your sensor:

- Take a photo of the blue sky (or some other smooth surface) at a high f-stop (f/22 or higher, as high as your lens can go). Set the lens to manual focus.
- Open the photo in Photoshop (or your favourite photo editor) an apply Auto Levels to make the dust and dirt more visible.

The only cleaning I applied so far to my sensor was a couple of gentle blows from the Rocket blower (like this one (http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=259157&is=REG)).
