any tips to prevent fogging?
Oct 9, 2018 11:00:15 #
Just my opinion, but I'm leery of the plastic bag theory. Moisture does not move through plastic. I use a brown paper bag. However, 99% of the time I simply keep the camera away from vents, hot or cold.

Try Thiamine (B1) , Folic acid (B9), vitamin C, Calcium, Magnesium, Zinc. ... Oh, sorry. Wrong type of fogging.

As I mentioned in a earlier post, this happens to me here in SE VA when taking my camera from the AC'ed house to the outside for a sometimes a time sensitive image. I simply wipe the condensation off, (the UV filter), with either a lint free cloth; my shirt tail; or a Leopold Lens Pen. once wiped off it's ready to use. Better to chance damaging the filter than the front lens element. Contrary to the opinions/reasons to not use them which have been shared by other UHH'ers in another thread on filters, for me they do serve a valuable purpose and do not seem to affect the quality of my images. However, I am strictly a hobbyist and not a serious amateur or professional so..........to each their own. ;~)

Don't use a ZipLoc. It does "work", but a kitchen size plastic trash bag is better in every way.
You have only one solution and you are sticking to it. It's just not practical in all cases.
All you need to do is get the camera above the dew point of the surrounding air. There are lots of ways to do this. In semi tropical or tropical rain forest environments there are more practical alternatives.
For example, I was in Tikal in 1979 at the end of the rainy season. I had a Nikonos III because I knew that dampness would be a problem. I had not been in an air-conditioned environment for more than 24 hours. I took the camera from my canvas bag and when I removed the lens cap the glass immediately fogged over. There could not have been more than a 5 degree difference in temperature between the camera and the air but that was enough. The solution was simple. I laid the camera down on a rock, face up in the sun. The fog went away within a minute.
With a mirrorless digital camera you might want to point the lens away from the sun.

I understand why the camera fogged, so no science lessons please :-)). Just curious if anyone has any tricks to prevent or minimize fogging when going from a cooler temp to a moist warmer one?

I love living in California. This has never happened to me.

My trick is to keep the car at a temperature the camera likes. It may not be the most comfortable for me, but then that's not the issue.

120 volt is better, and a small, quiet Honda generator will supply all the power the hair dryer needs. It's a good way to spend $800.

Fogging is something that has been discussed here a thousand times. Place the camera in a plastic bag as you expose it to the change in temperature. Wait something like 15 minutes so the camera will acclimatize and then get it out and begin shooting. Do the same the other way around.
If the camera is inside a camera bag do not get it out in approximately the same length of time before beginning shooting.

You are correct, about a thousand times and each time the same type of semi- and totally incorrect answers mixed in with some correct ones.
As you suggest it is all about temperature and relative humidity.
From inside cool/air conditioned to outside warmer/some humidity will cause outside humidity to condense on the cooler lens/body parts. Wrapping the components tightly in a plastic bag will minimize the warmer air that contacts the cooler components. Allowing the components to warm up to the outside temp will then prevent the condensation. when the components are removed from the bag.
As simple as it gets.

I live in Florida and would never leave my camera in the Trunk of the car. The temperatures in the trunk are so high that it will ruin a battery and possibly cause out gassing of materials in the camera. I keep my camera in a waterproof case with fresh desiccant to insure that moisture in the camera and lens is kept at a minimum after being out in the high humidity. I place the case in the back seat and put a towel over it to keep the A/C off the unit. About 20 minutes before I get to my site I start turning the A/C to around 77-80 degrees. I then remove the camera from the case (car is closed so minimal moisture) and let it warm up. Once warmed up there is little chance of fogging. If I am in a hurry I put the camera in a zip lock and let it warm up. Learned this from taking the camera on a Cruise ship.

When I lived in Florida years ago the entire car could get a complete cloud within the air conditioned passenger compartment simply by driving into a heavy rain. Add plenty of heat into your ventilation system.

Has anybody tried Rain-X? I haven't and wonder if the image quality might suffer.

I'll test with Rain-X tonight with a paper weight lens and let you know the result later.

I wrap mine in a terry cloth towel and put it into a small, padded, camera bag away from AC vents. Don't have problems any more.

Phisohex has been off the market for a number of years. The "hex" was hexochlorine compound, suspected, now perhaps proven, to cause cancer. Replaced by Hibi cleanse.
