Neutral Density Filters


I've been researching several different brands of Neutral Density Filters and have noticed there are a host of different ones offered, .3, .6, .9, etc. What do these designations mean and do I need one of every grade? Thank you. . .

  Every .1 = 1/3 stop of light reduction, so .3 = 1 stop (2x), .6 = 2 stop (4x), .9 = 3 stop (8x). The amount you want/need will vary. If you think you'll use them often, get a set. You can combine them for greater light reduction, .3 + .9 = 1.2 (16x).

  Thanks, Jon. Are they all the same? I've noticed that Singh filters are really expensive. . .any other recommendations?

  If you don't want to pop for Singh, try Cokin.
