to humidity from a dry area


I live in MT, which is fairly dry, at a decent altitude (4700), and somewhat cold (though this season hasn't been too bad). I am going to Seattle tomorrow and just realized that I might have a problem with the humidity there? I know how moist it is with the rain and the ocean, so I didn't know if there were any precautions I should take, or if I needed to do anything differently as far as my camera/lenses are concerned. We are also going to go to a butterfly exibit, and the info says it has humidity of 60-70% -- this seems high but I really have no idea about humidty. We have wind chills instead =o) Does the pressure matter going from a high to a low altitude? Any tips you could share about the change would be greatly appreciated!

  60 - 70% humidity? That's a dry day down here in the South! ;-)

Going from altitude in Montana to a butterfly exhibit in Seattle, I think you'll definitely feel the difference. Don't worry too much about your camera, it will adjust faster than you do.

If it is cool outdoors, or you start off in an air-conditioned room, then go into the humid exhibit, take your camera out right away so that it can adjust to the temp and humidity change before you are ready to start shooting.

Make sure you have a soft lens cloth with you, but don't wipe the lens as soon as you take it out. The moisture will just condense on it again. Give it a few minutes to adjust to the ambient temperature, then wipe it gently.

Have fun,
Chris

  Thanks Chris! I had read in a past post something about ziploc bags? But I wasn't really clear on what to do with them. Do you by chance use them or know if I need them? Thanks so much!

  You probably don't need to worry about ziplock bags for this setting. They are more useful if you are spending a day at the beach.

If you want, though, you could put your camera inside a large ziplock bag, and keep it in there while it adjusts to the warm temp in the exhibit, but it will take longer. The moisture in the air would condense on the outside of the bag instead of on the camera. If you take the camera out of the bag after it has reached the room temp, then less or no condensation will form on it.

  Great! I really appreciate your input. Nothing like waiting until the last minute to get everything done. I best finish packing up that camera gear! Thanks again.

Kerry L. Walker   Gee Chris, are there really places in this country where the humidity gets that low? LOL

  I wouldn't know, neighbor.

Six more weeks of Winter???

It's February, and the first thing I did when I got home from work today was put on shorts!

Kerry L. Walker   It must be winter here. It's raining nearly every day! I hear the rain turns white up north this time of the year. Have a good weekend buddy.

  We had to wear jackets a few days ago. I guess that was our Winter for this year.

We actually had snow here last year for Christmas. Almost an inch! (chuckles from the Northerners)
