When it reaches 100%it is known as the Dew Point and condensation will occur Even desert environments can have high atmospheric humidity,which can soon reach 100% when equipment is brought out fromair-conditioning Condensation causes tape to stick to the rotary drum, which can becatastrophic Most machines will employ a condensation sensor that can preventoperation for as long as an hour Non-condensing high humidity can still cause much faster headwear High humidity can promote corrosion and fungal growthIn practice, always ensure that the camera is warmer than theenvironment and there will be no problem. If you HAVE to take a relativelycold camera into moist air, first seal it in a plastic bag (using tape) untilit has reached ambient temperature. You can accelerate this by turningon the camera while it is still in the bag. If long exposure to humidity isexpected (as in the Tropics) then store the camera (and especiallylenses) in an airtight box with generous sized bags of silica gel.
