Never keep your cameras – digital or film – in your car or in a cold room. Condensation builds up once you enter a warm room or building. That moisture is never welcomed to any electronic gears or glass lenses. Also the cold temperature wears down battery life. Working at a camera repair store, we find this a common problem. Baby your equipment, keep it from moisture, dust, sandy beaches, etc. and carry it in a shock proof bag. Put some silica gel sachets into the bottom of your camera bag. The little sachets will draw any moisture in your bag to them to save your lenses and DSLR from being impacted by it.
Protect your lens. DSLR sensor chips collect dust. You may not even notice that you have dust at all, until you stop down and shoot with a wide lens or macro. Or, you can check the amount of dust by Make your LCD monitor display a white or light grey screen (like the sky for example).Then, all of a sudden it looks like you are looking through an electron microscope or something. Prevention is always better than cleaning. For each lens you own you should consider purchasing a UV or skylight filter. Keep it attached to your lens at all times. In addition to it cutting out UV light they will protect your lens from scratches or even breakage.
Clean Your DSLR’s CCD. A sensor swab is wrapped with a special lint-free cloth and the tip is moistened with a few drops of methanol. This liquid makes the dust particles stick to the cloth for removal; a dry cloth will only push the dust around the sensor. Other than making your light background images look like a case of chicken pox, a moderate to severe accumulation of dust particles will cause a noticeable loss of contrast in your images.
In conclusion, make a search for Eclipse fluid or other brands that make sensor cleaning kits. In most camera stores youll find an alcohol based lens cleaning fluid that is well worth having. To apply the cleaning fluid grab yourself some lens tissues. These tissues are one use tissues and should be thrown away after using. Dont use normal facial tissues – these are too rough and will scratch your lens. An alternative to cleaning tissues is the more modern microfiber cleaning cloth.
