Here is an example of a long exposure, and lots of patience, photography. The method is pretty simple, keep exposing for as long as it is possible on your camera and hope the lightning occurs during the exposure.
Fine dust particles gold and yellow in colour were blown over large sections of New South Wales from central Australia. The Bureau of Meteorology somehow differentiated this phenomenon from the dust storms we experienced in late September. Apparently a dust storm and dust blown in by wind are not the same.
The photograph shows the dust coming from Sydney over the Central Coast, reducing visibility to few hundred meters. The photograph was taken from President Hill in Gosford just before midday.
