Thin blue residue or film after Copperhillimages' sensor cleaning

[HKFEVER]

I just got the Copperhillimages' sensor kit and try in on a reguler Hoya filter.

Whenever I left up the sensor cleaner (with eclipse) from the filter, there has a thin blue film or residue on the area of that particular area.

If I did not try it on the filter and directly try in on the sensor, then wow:( !!!!!

Can anyone help out?

How to avoid that film or residue?

I've seen the same thing when I tried cleaning a lens with Eclipse. I no longer use Eclipse to clean lenses. But I have yet to hear of something better than Eclipse to clean sensors, so...

On a lens this residue would have adverse effect, but probably not on a sensor. I certainly have not taken any pics showing signs of such residue after cleaning a sensor with Eclipse.

Tried Sensor Clean?

There's a rumor that Canon is going to proclaim Visible Dust as their only approved sensor cleaning method.

[HKFEVER]

I am sure the residue or the thin film will reflect the light with different wave length in different way. With the reflection, picture colour may be affected.

I just looked at that kit. They use large cotton tip applicators (Q tips) that are not even individually wrapped. You will most likely leave more dust and fibre debris then was there before.

I very highly doubt that Canon would announce anything other than blown air as an approved sensor cleaning method. That would then authorize their customers to stick things in side their cameras to clean the sensor. Canon would not take on that kind of liability.

I can't see Eclipse fluid being a problem.. It's just ultra refined isopropyl alcohol. It should evaporate with nothing left behind. The refining process takes out everything, including the water that isopropyl alcohol can draw out of the air.. (That's why it costs so much).

It could be that the Eclipse fluid is disolving something that's impregnated in whatever you're using for a swab and then leaving it behind as it evaporates. It could also be reacting with the coating material on your filter.

I've used Eclipse with the Photosol sensor swabs to clean my sensor a few times now and have had absolutely no problem with residue..

Not to mention that sensor cleaning kits should be used for sensors and not multi-coated lenses or filters. Use lens cleaner for lenses and filters.

I now have this after using eclipse as well. I am thinking about dropping my camera off in irvine to have them get rid of it. It causes a good amount of banding in higher iso's

How do you know this is the cause of banding at high ISO settings? It seems highly unlikely that this could cause banding. There are many other reasons that would be much more a obvious cause of banding: extreme contrast, colour or other adjustments on an 8 bit per channel image, or looking at photos using an 18-bit instead of 24-bit LCD monitor, for example.

[kawter2]

I'm not 100% sure this is the cause, I just know that i did not notice the banding @1600 until the sensor got the streaks. I found out after the fact, that i think i used too many drops of eclipse

Extreme contrast. it does not seem to be limited to this..

color or other adjustments on an 8 bit per channel image I notice this on my unedited raw images converted ot 16bit as well as my 8bit jpgs while viewing them on a 32bit monitor color palate @ 1600x1200 in magnifications of 100%/50%/25%


You might be completly right but I would be convinced until the sensor is cleaned and i still experience the problem

Thanks fo the insight

Ive never had a problem using Eclipse on my sensor but I realy have problems using the stuff on Hoya filters, I guess its the coating on them.

It happens not just the Hoya filter, also on the 16-35mm f/2.8L front len. But just very very little.

[MarkoPolo]

I too have had a similar experience with Eclipse and filters and lense front elements. Smears like crazy! It really doesn't make sense to me being refined alcohol, but I learned the hard way.

Hehe, the coating on multi-coated filters and lenses is on the inside of the lens/filter, not the outside.

I've just emailed the guy who came up with the method the link to this thread, so he can comment himself.

HKFever,

I think everyone who replied to your problem in this thread has backed up precisely what I told you in my e-mail to you earlier today. There must be some filter coatings that do not take well to being wiped with Eclipse, and that includes your Hoya. I have never used Eclipse on my filters or lenses, so I can't give you a first hand account. But after hearing from people a long time ago that the smearing that remains after the wiping needs a lot of "buffing" to remove it made me think twice about using it on my lenses and filters.

Eclipse and PecPads have been the safest and most reliable tools used to clean a sensor for a lot of years. If done according to the specific directions, there is an extremely remote chance of anything going wrong. As I told you earlier, if you still have a degree of confidence, go ahead and swab your sensor. And as someone else pointed out above, use lens cleaner and lens paper on lenses and filters from now on.

After your e-mail to me, I added a little note of caution about where to use and where not to use Eclipse in my tutorial. And I'd still like to hear if there is any permanent damage to your filter and lens, or if it's discernable at all.

No - the coating will be on any surface the designers wanted to control reflections from - whether it's inside or out.

You are aware of the well documented banding issues with the 20D at high ISO's, are you?

Has anyone tried using isopropyl alcohol for cleaning their sensor? I can't find eclipse in New Zealand, and it's reasonably expensive to get from Australia. Finding pure methanol is a little challenging, but the isopropyl is easy to get.
