Subsequent stroke, which happens at intervals of several tens to hundreds of milliseconds later, performs "an exposure" thanks to the fact that it "runs over" described temporarily created structure, at a time not exceeding a few millionths of a second, thus generated image as if frozen, but totally invisible (similar to a latent picture in Ag-halide gelatine layer).
Baadae kiharusi, ambayo hutokea katika vipindi vya makumi kadhaa kwa mamia ya milliseconds baadaye, hufanya "mfiduo" shukrani kwa FACT Hiyo ni "anaendesha juu ya" muundo Ikielezewa Muda umba, wakati si ilizidi millionths chache ya pili, HIVI yanayotokana picha kama waliohifadhiwa, lakini kabisa asiyeonekana (Sawa na picha latent katika safu Ag-halide gelatine).
