Can anyone explain how the flash power of the sb 5000 is displayed from low to high on the flash display? It Shows 1/1 is the highest and I see 1/128 as the lowest. will this setting affect the power of the flash?
I represents the flash duration with 1/1 being the longest duration 1/128 being the shortest. The longer flash duration the more light on the subject given the same camera settings. The flash manual will most likely have a chart tell the approximate duration for each setting.
