枫下拾英 / 摄影艺术 / 学艺不精，请教一个关于ND Filter的常识问题NDx2 (exposure adjustment = 1 stop, reduces ISO 1/2)
NDx4 (exposure adjustment = 2 stops, reduces ISO 1/4)
NDx8 (exposure adjustment = 3 stops, reduces ISO 1/8)
这里的1,2,3 stop(s)是不是指降1,2,3档曝光？
那和
ND.3 (exposure adjustment = 1 stop, reduces ISO 1/2)
ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4)
ND.9 (exposure adjustment = 3 stops, reduces ISO 1/8)
是不是没有区别？
