Cleaning Camera Image Sensors
By jason - up to 2007 (archived) • Apr 2nd, 2007 • Category: News for Creatives (archives)A tip from the New York Times:
“Devices for removing dust from the image sensor of a digital single-lens reflex camera are usually promoted by emphasizing the need for regular cleaning. Delkin, however, suggests that its SensorScope is mainly intended to limit cleaning.
This $190 device is a modified five-times-power magnifying lens for checking sensors to see if they are, in fact, dirty. Excessive cleaning of the sensors’ delicate surfaces can cause permanent damage that shows up as darkened areas in images. Because SensorScope users need to look inside their cameras, there are four light-emitting diodes that light up the sensor’s surfaces, assuming that the camera has been set to a cleaning mode that raises its viewing mirror and locks open the shutter. Some cameras, as well as some photographers’ vision, may require that the device be moved up and down for focusing.
If the magnifier does reveal dirt, which can also darken portions of digital images, the device comes with a tiny vacuum cleaner as well as cleaning wands and fluid.”
