Do not use your camera in wet weather if it doesnâ€™t have overhead protection. As a makeshift camera protector, you can use a plastic bag. All you have to do is to cut a hole into the bag. This hole is where the camera lens will go through. Put a UV filter on the lens and gather the bag against the UV filter. Use a rubber band to secure the plastic bag on the UV filter. This method can only be used for cameras that have extended lenses and can be fitted with filters.
If the camera has been sprinkled with water, wipe it down with a soft cloth. Remove all the detachable elements and wipe them each individually. Keep all the camera compartments open until it dries completely.
If an unfortunate accident caused your camera to become submerged in water, there may be a small probability that it will still work, especially if it has fallen into fresh water. If it falls into salt water, however, it is highly unlikely that it will work again, because the salt corrodes the camera components. Still, you should try rinsing it in fresh water, and then letting it dry. The salt may have only caused minimal damage, not enough to keep the camera from functioning.
When the weather is extremely hot, be sure to protect the camera by shielding it from the sun. If you decide to cover it with a piece of fabric, make sure to use lightly-colored cloth as dark material absorbs more heat and can cause damage as well. Also, you have to check if the material has dirt, sand, moisture, or any other element that can harm the camera.
Conversely, when the weather is extremely cold, you have to take special notice of the cameraâ€™s batteries. These are the parts which are most susceptible to damage at very low temperatures.
Finally, if condensation develops on your camera, you should remove the memory card and the batteries. Condensation is very hard to wipe down, especially if it is inside the camera. The best thing to do in this instance is to wait until the condensation dries out on its own. You can also put silica gel in the place where you store your camera. This gel absorbs moisture such as condensation.
