In and out of the cold

The key is isolation from the change in relative humidity when going inside from outside AND managing a slow temperature change.
That is why I recommend using an insulated bag with a sealed compartment.
But I do NOT recommend using cooler packs.
Condensation may occur when taking a cold camera into a warm environment; a cooler pack will just prolong the duration of this possibility.
When in the train car you may wish to change your battery, memory card, view images, etc. Once the camera warms up a bit it can be removed form the bag and you can take care of these normal things.
Bottom-line: If the camera is allowed to warm up slowly while in a sealed bag, everything should be fine.

I have been on this shoot three times this year, January, May and three weeks ago in October. Hope and pray for snow. I would shoot in RAW because the lighting will change a great deal throughout the day. Stop by your local grocery store and buy the insulated bag for frozen foods and keep your camera/lens in it. The two cars for the photographers are heated but the distances from one runby to the next are usually short. They don't usually allow standing in the vestibules when going from one location to the next. I haven't signed up yet because I'm waiting to see what the weather is going to do. If there is snow and cold you will get spectacular shots especially Helmsetters Farm. Have fun and maybe I'll see you there.

Email from Cark Franz several days ago said they were about sold out - 85% sold on 12/13. Hope we meet.
I have some industrial silicagel packs I'll also put in whatever bag

Most camera bags that have an exterior of nylon/taffetta type material & that will zip up tightly & allow the camera & lenses to warm up slowly enough to avoid condensation. In the past I would put the camera in a sealed large bag to warm up slowly, but found that many camera bags use a type of foam padding that tends to act as an insulator & holds the cold air in allowing equipment to warm slowly. I am very particular about the way I treat my equipment & have found this method to work quite well. I will usually wait at least an hour before opening the bag, but sometimes when having been out shooting in temps of around 0 deg F or lower, I will wait much longer. In 30+ yrs of photography, I have never had a lens get mold or fungus on an inside element. Outside of the studio, winter is my biggest photo op season.
This was shot during a blizzard at the crest of a hill. This fence is on an Amish farm.

Small Dehumidifier Bags Mildew Mold Damp Moisture Absorb Condensation. Do these help? I have them in all my cases, but don't know. Bee

You will be seeing some spectacular scenery - My son and I took the trip several years ago in the summer, but had no stops for photos. I grew up in Cumberland. Temperature in Frostburg will probably be much colder than at Cumberland.

I also took the trip one summer - just the ride up and back. The only photo op was when they put the engine on the round-table in Frostburg. Unfortunately that was before I got "camera-happy".

I think you are wrong here - bringing any cold item into a warm, especially humid, room will cause condensation. Try it with your eyeglasses or sunglasses.Going into the cold from the warm is not the problem but the other way.

for the extreme solution, ask the organizers if they have a car that can be run the day without heating. 40F isn't that cold. Just dress for it. If the cold gets bothersome, you can leave your equipment in the cold car (ask someone to watch it for you, to be sure), and go to the warm car to warm up.
I'm guessing that, if you ask around, you'll find other photographers on the trip that would like that sort of solution.

Interesting post. This sounds like a great trip. I will be anxious to see some of the photos.

For extra protection I have in my camera backpack those silica of gel packs to control condensation problems seen to work very well for me. However a plastic bag for storing a camera in is also a very good solution to, I think I would put one of those silica gel packs in the bag as well could not hurt!. All those who have posted have given you a lot of things to try and do. Good luck with the shoot, take lots of pictures and post a few..........Richard

I 'am leaving for Australia & New Zealand Jan. & Feb. 2013,my concern is with 35-40c plus high humidity will have on the camera, lens & media card,and going onto "air condition". Would placing the items in ziploc bag help reduce condensation?

Well, you probably have more advice than you wanted. All you need to do is stop condensation from the air in a warm humid area from forming on your cold camera. You can do this in several ways: don't let your camera get cold; isolate your cold camera from the humid air or leave your camera in the cold. I would put my camera and lens in a large zip lock bag and only take it out of the bag when outside then return it to the bag before coming back inside. When the shoot if over let the camera warm up fully before opening the bag to download pictures. Change cards and batteries outside.
