Step 1. Trouble already. The sparkley stuff is salt and/or corrosion caused by the water.

For this dissection, I'm referring to the EOS 20D Parts Catalog as found (in PDF format) here:

Hey Gil! Thanks for your kind words. Sorry about not mentioning what happened to the camera here. I did post the story on a couple of message boards, but I guess I should re-tell it here. The short version:

I was on honeymoon in HI a few weeks back. While walking along the shore, I slipped on some algae/seaweed covered rocks and fell. My arm (holding the camera) took the brunt of the fall, but the right hand (holding the camera) hit a shallow tidal puddle. Only a bit of the camera got wet, mostly on the rear, near the battery cover (the water didn't even reach the bottom of the LCD on the rear of the body). This killed the camera immediately. I took it back to my hotel and let it dry out (a huge mistake). It never worked again. When I got home, I sent it to Canon to see if they could repair it. They totaled it and sent it back un-repaired. When I got it, I decided it would be cool to take it apart and document what I found.

Luckily, the camera was insured, so I upgraded to a 30D when I returned home. I used the new 30D to take the photos of the dead 20D.

I just ran across this set of pics when someone directed me here.. absolutely fascinating. Thanks for the postings!!!

I have never seen the insides of one of these beasts! What an eye opener!

But, what is the story behind it? Why is the camera so badly corroded? If you have covered this elsewhere, I am sorry to be so ignorant of it. Direct me to the appropriate website where the discussion is covered... if I is.

As I said, really fascinating! I would love to see the insides of all the different cameras, actually. I guess I should do a search of some kind..... Anyway, thanks for letting us see all this!!!!
