The recent dust storms have drown countless people to photograph this unusual for Sydney weather phenomenon. It has to be said the dust represents not only danger to the health of the photographers but it also represents real danger to their equipment. The dust is reported to be finer than talcum powder and thus has the capacity to enter your camera and lens. It would be very difficult if not impossible to remove. If you are photographing the dust storm scenes cover your camera as much as possible, including the lens, and reduce the duration of exposure to the weather.
