What's the simple rule on how to avoid condensation? Living in Australia especially on the Gold Coast where "winter" is 16C (or 12C at worst and rare), no snow, etc. I haven't really come across any issues. I have taken my camera to Colorado in winter, hiking in the snow and snow blizzard, and measured the temperature at 0C (32F) or probably less but I was too cold to bother checking the temp, take photos there etc and haven't experienced any condensation.
So my questions:
1. When and how would it happen
2. What to do to avoid it
thanks in advance
The worst condensation I experienced was using a camera in a green house after leaving the camera in the car in below-freezing temperatures overnight... I warmed the camera and lens up by holding it in my hands for 10 minutes.
Condensation when warm, wet air comes into contact with relatively surfaces.
The dew point of air is the temperature at which condensation will occur.
If your camera is warmer than the dew point, you will not get condensation.
... so keep your camera and lenses warm.
I spent a few weeks at Useless Loop, (Western tip of Oz) where it was so dry they extracted salt from sea water.
One day I stood and starred at the sky because I had seen something unusual - it was a cloud!
