Digital Camera Maintenance
Although they are constantly falling in price, digital cameras are still costly pieces of equipment. This is particularly true of 'prosumer' (that is, the upper range of the consumer market) and professional kit. It is strange, therefore, that so few photographers take good care of their tools. Maintaining an effective cleaning regime for your camera may seem like a chore, but it will dramatically increase the lifespan of your equipment and will have an immeasurable impact on the quality of the images that you can produce. Furthermore, basic maintenance tasks can be basic and quick.
Lens MaintenanceIt is particularly important, whether you are using a film or a digital camera, to ensure that the lens is kept in good working order. This begins with very basic rules such as ensuring that you always keep a lens cap on when your lenses are not in use, as well as making absolutely sure that the other end of the lens (the glass that fits onto the body of your camera) is kept covered at all times. You should also regularly clean both of the glass surfaces of all your lenses with a blow-brush, cloth and cleaning fluid. As this article focuses on digital camera maintenance, further information on lens cleaning is available in an article elsewhere on this site concerning the maintenance of film cameras.
Perhaps the most important part of your digital camera is the image sensor. This is the element of the camera that will cause the most obvious degradation to your images but, annoyingly, is also one of the parts that most easily accumulates dust. In most cases, a few specs of dust on the image sensor are bearable; these will appear as small blotchy patches on your image, and can easily be removed in your image editing software. The most tool for eliminating dust marks is the clone stamp, the use of which is covered in more detail in another article on this site.
