Sensor cleaning- please help

Allright, so I’m an idiot. I tried to blow out my sensor using a too-full can of canned air – long story short, it sprayed all over my sensor and now I have a soft and dreamy look to all of my pictures.

Anyone know if just a sensor-swabbing will clean that off?

After that, does anyone know where in the hell to buy sensor swabs in the Karachi/Lahore/Delhi area?

For the love of god please help, I am starting to look like a pictorialist.

scott, man, i’ve always been afraid of that! to the point where i photoshop dust off the images until it gets too bad, and then i hold my breath, and blast away. what are you guys doing in karachi? i stayed at the avari tower hotel when i was there, best place in town. if you get a chance, go down to the beach, the indian ocean, and check out the weird scene with trained monkeys and camel rides and women going into the water fully clothed. also there’s the shipbreaking yards of Gaddani, where these guys literally blowtorch gigantic old ships apart by hand, one piece at a time. when in lahore, check out the famous singsong girl / red light district, although christie may disapprove!

Scott, contact deepak puri at the Time Life bureau in delhi. Asia is his house — there is nothing that goes down in the region that he doesn’t have a piece of — and if you and christie are going to base there, you must meet him, it’s a rite of passage. send him a big up from me, and thank him for hooking up my flight to columbo. (he’s in the directory).

ps. can you tell me exactly how you sprayed your ccd chip to achieve this soft and dreamy look? it sounds enchanting.

Damn, where were you three days ago? I am outta here tomorrow morning, but hopefully I will be back soon, I like the sound of camels and monkeys performing for my amusement on the beach. And how can you not like ship-breaking? Smoke/haze, fire and ship-breaking will always make for fine pictures.

I spent the better part of an hour this morning going booth to booth in the camera bazzar here trying to explain what a “sensor swab” was. After getting the same lens cleaning kit handed to me over and over I enlisted the help of a local photographer, still to no avail. That is the last time I get lazy/stupid with the canned air.

Teru, is Deepak a LS member with contact info listed? Wasn’t he in Indonesia?
….. And yes, it is enchanting, but it is tough to come off as hard core with that whole “diffusion filter” look.

Scott, search in google “cleaning sensor rob galbraith” and you have some information about but all is for when you are back in home. If you need to clean it now maybe the same lens cleaning kit can help you.
Good luck

It is so sad that scott and I now communicate through lightstalkers. Or is it really romantic? a lightstalkers love story?
Can’t wait to see your new work, sort of VII meets the Kmart photo studio, I know it will be very powerful.I’m sure you like the sound of camels, scott – you can hang out with them while i check out the singsong girl – but you better come back to delhi soon. A guy tried to sell me a lint brush by rubbing it on my arm and I almost shoved it down his throat – I think I need some sort of zen/yoga intervention.

I had to clean my sensor about a month ago, sans sensor swabs. Here’s a webpage I found when trying to find some ideas. The guy says to use pure methanol, a popsicle stick and some lens tissues. He also says you may have ruined your sensor if you spray the liquid contents of the canned air onto your sensor. Good luck.

hello internet lovebirds,

deepak puri has an LS profile, and I doubt he was in indonesia. he’s not a photographer. I forget what his title is at the Time-Life bureau in delhi, but his is the “The Man” throughout South Asia, and a good piece of the rest of it. So, I doubt he will know how to clean a CCD sensor, but he will know who’s running a professional grade gearshop in your area. failing that, he can probably speak to the local military commanders and have you airlifted to the nearest city with a canon authorized repair center.

as for the warm fuzzy hardcore look, don’t you remember early DC Emo? think Rites of Spring or Faith. or even Supertouch from new york.

ps. Christie, young ladies should not be wandering alone in Delhi without tear gas or brass knuckles. I believe that city holds the title for the greatest concentration of ass-grabbing assholes per square kilometer on earth. One one weekend visit with a lady friend, I punched out three guys in less than 36 hours.

“Note: Do not use any sort of “canned air” for this. It may be too powerful and the types that are liquid driven can “spit” liquid in the gas stream and if that happens you can wave bye-bye to your sensor. They may also freeze the sensor, which again could result in damage"

Well shit.

Thanks for the link, good stuff. Now I will spend the next week of my life searching for pure Methanol…… And man does that sound like I’m looking for drugs.

one more thing, CH4O is the chemical symbol for methanol. Maybe that can help you find it. It’s also known as methyl alcohol

Scott FYI, this is whats in those canned air (its not just air)!

I suggest buying one of these:

They are cheap like $15-$20.

a note to all, just a very basic dusting tip darkroom 101: before you spray anything with canned air spray a little bit pointing into nowhere. i usually shoot it a couple of times to make sure. sometimes the liquid builds up and testing it before each spray is the only way to know you’re safe….and of course when you spray make sure it’s level. i’ve never had a problem after the first initial sprays, so i’ve found that test to be reliable. ….and nelson, stop drinking that CH4O shit, i’m beginning to worry about you. again.

Just a note. Thre is NO canned air. They are all Fluoro Ethanes. Or similar compounds. So DON’T spray them on a CCD/CMOS chip – actually the low pass filter in front of the chip on most digital cameras. Its slightly oily at room temp/above normal pressure. As they expand they also chill rapidly and condense water out of the air as well. So DON’T use them in the camera. You’ll be able to clean the chip with pure methanol (CH3OH) and lintless swab.

Good luck

I didn’t read the entire thead but I have a great system. Go to spend the money and your dust problems will be gone!!
The brushes are cheap when you think about it, you can use them over and over and over. Also you have to get the senor clean kit and the chamber clean kit, the entire package is AWSOME!! the chamber clean is key to cutting down on dust, it gets rid of all that crap that get flicked around by your mirror, everytime we change a lens metal filings enter the chamber and well that’s NOT a good thing (thanks to Martha for that line!) The only problem from what I hear from shooters in my city is that they are back ordered but is worth the wait!!!!!!! Contact me if you need any more info. Let them know I sent you to their web site because they’re sponsoring a big photo essay project I am putting together.

Dust will be a thing of the past with this system.

All this is good info. And I have learned my lesson.

The absolutely incredible, remarkable, spectacular thing is- since I screwed that body up and am waiting for some sensor swabs to come in, shot something on a tight deadline this morning, and my other body decided to read “Error 99” and now perpetually shoots frames whenever it is turned on/touched/looked at from across the room.

Was switching to Canon a mistake? Have I karmically done something so terrible to warrant this?

…wait, don’t answer that last one.

As for the canned air, I wouldnt use it on the sensors, and even in the lab I am nervous using it on my precious negs, but as Jake suggested a few initial bursts into the air will clear the pipes, and you must be careful never to tip the can downwards when blowing out the “air”. I always shoot slightly upwards and so far I have avoided contaminating the negs.

As for ass-grabbing in Delhi, it is true, there are many wayward hands in Delhi, not just grabbing ass but picking pockets too. My first week in Paharganj, my pocket was picked three times, though I caught each one of them and gave them a drubbing. After that, I guess the word got around and they left me alone. I also witnessed alot of ass grabbing, bold leering, lewd gesticulations, and asinine commentary (a far cry from the Latin piropo, which occasionally rises to the level of real wit). However, my then girlfriend and I avoided these problems by donning the local gear (Kameez, kurta for me, shalwar for her). Delhi was 106 to 110 degrees then, so the cooler, lighter clothing was welcome, and the billowy length of the shirt prevents access to inner pockets and looks less provocative to horny hardup male Delhians. Course, Western clothing and manners have become so much more prevalent, you might look rather silly going about dressed in Indian clothing.

should I be offended that no has tried to grab my ass? All I’ve got was a ten- year-old boy who asked if I wanted to make out.

Here is a question. . .a friend of mine claims he’s been able to clean the sensor on his S2 with a lens cloth—that has made me flinch every time he repeats the story.

This is not on a pinch, this is how he regularly cleans it. Wouldn’t that be a terrible idea?

I’m way too terrified of killing my D100 so I’m taking it to a shop and will let them deal with it.

I would be lying if said it wasn’t a bit tempting. But tray processing sheets of 8×10 in my bathroom here before scanning/filing, not to mention taking that damn thing out here (if the tiny 20D draws a crowd….), not to mention carrying that god damned thing around, with film holders, tripod, etc etc etc again….

I take it back, I wouldn’t be lying.

….ok a leica could be nice.

You know what, I am half thinking about it- here is my gripe, and I really should make it a new thread…

After a long drawn out ordeal with Canon (I can’t remember what I have written and where about it- long story short, one camera got five minutes of rain and died for five days, the other just completely broke out of no where and is sitting in Canon’s repair in Delhi, waiting for weeks on a part, which apparently no one in the world can fed- ex it to them) , including emailing about five or so people there, corresponding with Chuck Westfall back and forth, Canon’s people, Mr. Westfall most of all, basically passed the buck to whomever they could think of and politely told me to piss off.

I have to tell you, I had heard bad things about Nikon’s service, but after these last three months with Canon (and hearing the same stories from some other LS people) I don’t think I would have made the switch knowing what I do now. These 20D’s are nice to shoot with, but even the D70 held up waaayyy better than these pieces of crap.

Canon gets a major thumbs down from me at this point.

old thread that i’ve only just read through and i just need to reply to teru’s comment from early on in it: teru, you made my night by name-dropping rites of spring. those guys had such a wonderful impact on me while growing up angry and punk rock. (faith, too, sure, but maybe ignition more than faith.) thanks for bringing up rites of spring, who are still able to make me feel simultaneously ecstatic and heartbroken.

and scott: very sorry to hear about yr 20d problems, b/c of course, it sucks to hear someone’s having trouble with their gear and also b/c i just bought one a few months ago, though mine’s not seen any very extended shooting yet (can’t bring myself to stop shooting the m6’s). that said, i’ll be heading to delhi in mid-may, if i can help somehow—-maybe i can bring you some swabs or a giottos rocket blower? pm or email me . . . .

by [former member] | 10 Apr 2005 23:04 | New York City, United States | | Report spam→
wow, that rocket blower would be sweet- you should see what they sell here.

I thought I would stop bitching about Canon, but since this thread was dug up today here is the latest update-

After over one month at the Canon repair center in Delhi, the only repair tech told me there was a chance it would be done this week- I called this morning to find that he has left on vacation, and now it is anybody’s guess as to when I will get it….

maybe I should just ask you to bring me a D70….

Ouch, dude. You sound miserable. You have soooo turned me off to the switch. I emailed a friend at SI to see if they can get you another contact number at Canon to have some one to unload on. I’ll try to send you the name and number before end of business tuesday.

Christie— I just punched a guy for grabbing Shiho’s ass. No make out proposals yet.
