Many manufacturers specify to not use their cameras under 0
degrees, but most cameras will work well in even lower temperatures. Cameras are not
tested at temperatures below 0 because problems can occur, but most of these problems can be stopped . There is really not a problem with electronic circuitry because
electronics often work better at lower temperatures. The problems that arise in
cold weather are related to battery issues and problems with the LCD displays.
Most cameras are fine to at least 20 degrees below zero, but what temperatures cause
problems all depends on the design of the equipment.
If you have older cameras, you need to winterize
them before you use it at extremely low temperatures. You will have to take the
camera apart and remove the heavy lubricants on their mechanical parts. It
should be replaced with a low lubricant or no lubricant at all. When you want
to use your camera at normal temperatures again, you need to replace the
lubricant. This is not very convenient and is not necessary on cameras that are
made today. The best things to use at low temperatures is memory cards, not
compact flash micro drives because they are mechanical devices and are more
likely to have problems.
There are a few problems you should know about before using
film at low temperatures. At very low temperatures, film can become brittle and
can snap very easily. Also, when there is very low humidity of cold air, it
allows static electricity to build up and this can cause a problem during
rewind. Sometimes static discharge will leave marks on the film, which will
ruin your photos.
Another good thing to
know is batteries lose a lot of their power at low temperatures. All batteries
will lose power at low temperatures, but some are better than others. The best
batteries to use in cold temperatures are non-rechargeable Li Cell batteries, NiCd,
NiMH and Li-ion batteries. There are some cameras out there that use an
external battery pack that connects to the camera with a cord, so you can keep
the battery warm under your jacket.
Whenever you come inside into the warm after you are
shooting in cold temperatures, there are more problems that can occur. The cold
air outside is really dry, but the warm air inside contains moisture. The
problem with the moisture is not on the outside parts of the camera, but more of
a concern on the internal parts of the camera. The moisture will eventually
evaporate, but it will take a long time. This problem can be avoided if you
seal the camera gear in an airtight plastic bag before you come inside. There
may be some condensation on the outside of the bag, but the camera and the lens
will slowly warm up and will stay dry.
