i know this filter will helps to take smooth water surface, but want to know how it benefits us? Can i say we can take at a faster shutter speed and yet still achieve the desire exposure for smooth water surface.
take for example without filter, at f5.6 pointing at a clear water surface, i half press the exposure timing shows 1/4s, so now if i put on the ND106 filter, at the same f5.6, what will the exposure timing be? can i say ND106 is 6 stops, so the exposure timing will be 1/256s base on the below 6 stops calculation.
1/4s, 1/8s, 1/16s, 1/32s, 1/64s, 1/128s, 1/256s
i am looking to buy a ND106, or ND110 filter, but just want to clear some doubts
