Just a reminder to all and myself. The problem with salt water is
the ionization of salt and dissimiliar metal effects. If you are
talking about an ocean liner then there is a lot of metal to work
with and even then they make allowances for the problem.
Even the tinyiest (science word) bit of water that gets in the
camera has ionized salt in it. Given the small thicknesses of
metals, conductors and components in the camera causes it to be a
problem. They can be etched out quickly unless they are gold
plated (which some are). Drying it out doesn't change things. The
minute your moist breath hits the inside of the camera (or humid
day) the dried out microscopic salt residues that are still there
to go back working.
How much and how long before damage is noted on a photo - who
knows. I certainly don't want to drop mine to find out but it
would be a good experiment for Canon to run for us!!
The suggestion to wash and dunk in distilled water is a very good
one. There might be a component in the camera that is water
soluable but I doubt it. The thing about distilled water is there
are minimal/no ions in the water. It is pure and pure distilled
water won't hurt the metals/plastics in the camera even if
submerged continually in it. If there is no distilled water use
fresh water - it is better than salt water of any strength.
The fresh distilled water is there to keep dilutting the little
residue bits of salt that are just then (several days later while
making your way home) finding their way out. Continually replacing
the distilled water keeps the free air oxygen away from the metals
and stops the oxidation. There is some oxidation underwater but it
is less of a problem overall than the massive ionization problem.
Remember you don't have any idea where the initial salt water
really got to, so until a repair guy opens it up and really dries
it out, you have to assume the salt water got everywhere.
It will be the lesser of all of the possible evils.
excuse any spellllling errors! It's early yet. Let us know what
the Canon reps say. Personally upon reflecting on it - it would
scare me to death.
Best of luck
