Hi Bob,I live in Rio de Janeiro, Brazil. You are correct about salt
water, salt spray is terrible, you must be living at least above the
tenth floor to reduce the effects of salt spray.. Sweaty hands or
fingers touching the shutter blades will corrode them. I take great
care in mounting large format lens on lens boards. I often wipe light
oil embedded on a felt pad over the cameras and lenses, sparingly. I
never put oil on shutters or curtains, they need special lubricants,
often graphite. Also I don't keep cameras and lenses in leather
containers/bags, leather is nice but very hygroscopic, I only put my
equipment in leather cases when I travel. In tropical climates it is
best to leave all your apparel exposed to free moving air than in a
closet, it is better to clean the dust over your lenses than throwing
away your lenses because of fungus. I stay away from salt spray, if I
have to photograph surf, I protect my cameras with plastic bags, only
the front of the lens is exposed. I still have my Nikon F2 and my
Leica M3 working.all the best,Jacques
DEAR ERIC,
As I also have lived in a tropical country for 18 years
(Barbados) I agree completely with Jacques. A box with small heater
can help but warmth introduces its own possible troubles. The best,
as Jacques said, is either an air conditioner or dehumidifier. All
three of my A/Cs have a dehumidifying setting. It uses less
electricity than the cooling function, doesn’t cool the room as
much, but definitely lowers the humidity…I have a hygrometer and the
A/C on either cool or dehumidify function bring the rel hum below 50%.
I bet that the reported rusting of the Leica shutter
blades came from someone living near the sea where there is a LOT of
salt in the air. Even here, A/C works best.
As I keep my office and dkrm at 75F and 50% rel hum, the
small fogging on the lenses when I take them outside lasts about 3
minutes and is clear from then on. Small price to pay to prevent
fungus etching the coatings and surfaces of my lenses.
Lastly, as I store a lot of finished prints in my office,
I can’t use the heater option.
MERRY HO-HOs & HAPPY NEW-NEWs!
BOB
PS: Jacques, where in the tropics do you live?

Eric,
I live in a tropical country, if you stay still for 5 minutes mold
will grow over you. The best thing is to use an air conditioner, next
a dehumidifier (it is really an inside air conditioner with a bucket
to retain the water taken from the air inside your room) and the last
way is silica gel in an airtight container. If you keep the room
ventilated or your closet were your cameras are going to stay with
breathing holes in the bottom and top and have a small heat source
inside and at the bottom, air will circulate and your relative
humidity will go down. Hasselblad had a small booklet
explaining the storage of photographic equipment in tropical
climates. Buy a RH meter and check the relative humidity and your real
necessity of spending money on an expensive equipment.

We have had a piano for over 50 years. Inside is a bar that acts as a
dehumidifier.
This is similar to what we have. I've no idea if it will work for you
but just an idea..

In talking with some folks, the humidity where I'll be moving to next
year is a concern for camera gear and prints.
I've not gotten a price quote yet, but am wondering if there is a
simple inexpensive way to make a cabinet that can achieve similar
results as a pro cabinet like these. It would be better to have
something that doesn't cool too much if at all as condensation upon
removal of a camera etc, would perhaps negate any benefits.
