My T3i Healed Itself

Here's the background of my story: I was on vacation, walking around outside and had my camera out. I got caught in a downpour and couldn't find shelter quick enough. I eventually made it back to my hotel and dried the camera off, and it seemed to work fine. A few hours later, I want to check the pictures I took and now it won't turn on. It just beeps when I switch it on and beeps twice if I press any buttons. I take the battery and card out overnight, and same problem in the morning. I figure the camera was toast.

Fast forward a few days to now, I'm home and getting everything ready to send the camera to Canon to hopefully have it repaired. As I'm about to box up the camera, I decide to try it one last time. I pop in a battery and try it. No response at all the first time. Then I realize I left the battery door open. I close it and switch it on again. It miraculously comes to life and it brings me to the date set up screen. I set the date and time, put in a card, and make several test shots. It seems to be recording everything to the card correctly, responding as expected when I press the shutter button, and otherwise functioning normally. I'm about to figure that I just got really lucky with this.

Now, my question is, how reliable is this camera now? It was water damaged to the point that it wouldn't function. I've had cheaper electronics that I've water damaged, but seem to work fine after they completely dry out. Is this camera very likely to malfunction on me again in the near future, or are my problems most likely behind me assuming I take care of the camera properly (and don't leave it out in rain again)? Should I still send it back to Canon regardless and have them fix it up, or just not worry about it and be more careful?

I don't think Canon can (or will) do anything to "fix" a water damaged camera.

If it's working now, the most likely long term damage will be corrosion. If it's dried out inside, then there's not much you can do about it now. Enjoy using the camera until it dies.


Cheers, Damien

Right. At this point there is no telling what long-term damage has occurred. Once the water gets onto anything electrical, corrosion will begin. This could be a matter of days, months, or even years depending on exactly where the water was, how much water was there, and what impurities may have been in that water.

But, unless you are shooting jobs as a pro, there's no need to rush out and replace it. There is little Canon can do in regards to service. It's definitely not covered under warranty. So just enjoy it until it quits working. And please do us all a favor and don't sell it to someone. :-P

Canon will not do anything to fix a SALT water damaged camera!

Fresh water (distilled) does not itself carry corrosive chemical salts; maybe calcium or other things in tap water that spot glassware. Pool water is not 'fresh water' per se...it has chlorine and possibly other buffering chemicals added. River/lake/ocean/well water carries lots of dissolved mineral salts

A good dip in distilled/de-ionized water would have been good to do, right after the original dunking, followed perhaps by a pure alcohol dunk to absorb residual water.

Rain water is close to distilled. It may have gathered some impurities as it came down, especially if it was rain in Hong Kong, Tokyo or L.A., but if the OP was vacationing at Aspen it should have been pretty clean.

OTOH, the pH of rainwater is about 5.6 (mildly acidic) because of carbon dioxide dissolved in the atmosphere. This CO2 reacts with water vapor in the atmosphere for the following reaction:

CO2 + H2O ---> H2CO3 (carbonic acid)

then that dissociates: H2CO3 ---> H+ + HCO3- (bicarbonate ion)

the bicarbonate ion can then dissociate: HCO3- ---> H+ + CO3- (carbonate).

Note the two Hydrogen ions...what makes things acidic.
I have even read that in more recent years, in 2009, rainwater has a pH between 4.3 and 5.6, even more acidic. In some areas of the United States, the pH of rainwater can be 3.0 or lower. Acid precipitation in the range of 4.2-5.0 has been recorded in most of the Eastern United States and Canada. A large increase in the concentration of NO and SO2 significantly affects the pH of rainwater.

Nice work. For those unfamiliar, deionized water has a PH of 7. Anything lower is more acidic. Anything higher is alkaline. Both ends of the spectrum will encourage corrosion. I would never count on rainwater being "pure" by any means as it grabs other crap from the atmosphere as the drops form.

My wife teaches kindergarten. They learn to count to 100. pH only takes counting to 14 (I will admit that one needs to understand decimals) :)

For what it's worth, I road around with a GPS on my motorcycle all the time. Covered it with a plastic baggie, but sometimes in nasty weather it would still get wet. The first time it happened water got into the screen, and I figured it was toast.

I let it dry for a couple of days and the screen was fine. That was years ago, it still works. I would wager you will want a new camera for the technology before it dies from water damage. Of course I would try not to repeat that experiment ...

Use the dang camera! But it may need to be replaced!

. . . except that pH is a log scale, so understanding decimals may create more confusion than clarity! :)
