Cold Weather Tip (Page 3): " Before going from cold to hot, wrap your camera and lens in a ziplock bag or trashbag. You can also use a more expensive dive bag just for this purpose.

" Before going from cold to hot, wrap your camera and lens in a ziplock bag or trashbag. You can also use a more expensive dive bag just for this purpose. Once youre in the warmer environment, let the camera acclimate for about twenty minutes before opening the bag. Any condensation will then build up on the bag instead of your camera." from The science of lens condensation

Here's one I had never heard before. The most important piece of advice I could offer is simply to take all your lenses out of your bag when you get home. Take off the front and back lens caps and let them thaw out for a few hours. If you leave them on theyll get condensation in them and mildew can grow on the glass.

You know all those silica gel packs you throw away? Save 'em, line the bottom of an old camera bag with 'em and store your lenses there. Any thermal buffering is helpful, too. Slow temperature change and humidity absorption will help... Just sayin'.

I believe this to be worded incorrectly as it impies to bring cold equipment into a warm environment. I believe it should have stated that as an added extra to our normal methods, to remove lens caps etc. so air can circulate and dry any moisture so it can't fester in the small enclosed gaps. I have done this for years.

When shooting in cold (and we have a lot of that here) I never replace the lens cap when I bring the camera inside but do leave it inside the bag to warm slowly sans the lens cap. Could be something to do with the fact that I always put the lens caps in my pocket so they are warm to start with.

Anyone who wears glasses knows all to well what happens when you step inside, from being outside in the cold. Instant fog over.

I also get those ads and have wondered about the money. How much will they pay? When do I get the money? Can I deal with more than one at a time or do they each expect an exclusive arrangement?
If you find out, please let me know.

I leave my equipment in my well padded camera bag and it warms slowly. No problems so far (about 40 years experience of doing it that way).

Short and to the point... YOU ARE CORRECT! Condensation only occurs from "Rapid temp. change" from cold to warm. Been doing the same as you for 40+ years also. If it isn't broke, don't fix it. Thanks. Boone

I have the opposite problem. Here in southeast Texas taking the camera and lens from an air conditioned home outside into a very hot and humid environment is a problem.

:thumbup:

I reckon you've nailed it Ore-D
Hot humid places are worse for camera equipment
moisturewise than very cold places by a long chalk.

Water vapour (humidity) in hot air will readily condense
on a cold lens, in fact there are places where water could
literally be running off a cold object like a camera taken out of
a cool air conditioned place (or a beer can taken out
of the fridge)
and into a hot humid environment.

Dry air is your gears friend.

I reckon (correct me if I'm wrong) in very cold climates air is dry as much water vapour may be frozen out of the air. Those of you with snow on the roof who have rushed off to the weather page to check your humidity, dont confuse "relative'' humidity with the amount of water vapour in the air.

So if the air is dry in your warm home removing the lens
caps to "thaw" your equipment would not hurt.

If your heating system is heating cold air drawn from
outside, drying the air further it, I reckon it would be a
great idea to remove the caps from a lens to "thaw it".

Would anyone reading this like to explain the difference
between humidity and relative humidity?

Very dry air can be a problem for humans so some space heaters have a facility for "humidifying". Perhaps MTs home or studio has one of these, or a steamy laundry or something else that is creating humidity inside when it is below
freezing outside... MT?

MagicFad has the best solution, moving to South Florida of some other warm climate area.

While South Florida is great (been there for 28 years), it also has a condensation challenge --
Florida's dramatic swings in humidity and air conditioning.
So it is going outside that causes potential condensation problems. The opposite of the problem we experience during the winter up north.

Jerry .. Thanks for the great advice .. I ALWAYS leave the camera & equip in the camera bag or plastic bag until they get to room temp .. never thought about taking filters off! :D Same goes for leaving inside the bag/plastic or otherwise when going out from an a/c room or car.. ALWAYS LET THEM ADJUST TO THE NORMAL CONDITIONS! :thumbup:

Since the cold air has little moisture content (low humidity,

I would put the cold equipment in a plastic bag, seal the bag then bring the items indoors.

A cool location would be best. Any condensation would form on the outside of the plastic bag.

Anyone who is interested in considering the plastic bag solution needs to be aware that they must squeeze as much of the air as possible out of that bag when sealing it outside so as to minimize the possibility of condensation forming inside the bag as well as that air warms up faster than the metal or plastic camera components.
