Try using some Fuji Velvia -- it has the very best color saturation I've
ever seen for spark pictures.  We shoot wide open f1.4 and 4 sec. times
exposure.  It also helps to have a vertical ground wire approx 5-6 feet long
hanging down near the coil as the spark "walks" up this ground wire and
gives some very interesting effects when photographing.
