I believe this picture is an example we could use here:

That's a high dynamic range image, and doesn't look like it used a grad ND filter. 203.132.66.13 09:36, 20 October 2006 (UTC)

Someone has pointed out to me that this page refers to ND2 as a 2 stop filter but http://en.wikipedia.org/wiki/Neutral_density_filter states that ND2 produces a one stop reduction Charlie Richmond 00:48, 30 November 2006 (UTC)

Isn't anyone going to comment on the question I raised above?? Charlie Richmond 15:49, 5 December 2006 (UTC)

Normally, this would mean 1 stop: 2^1 == 2. 2 stops: 2^2 = 4 ==> ND4. 3 stops: 2^3 = 8 ==> ND8. 4 stops: 2^4 = 16 ==> ND16. But this is just one of the possible notations. Mikus (talk) 04:26, 23 July 2009 (UTC)

2ND vs 1 stop reduction

Charlie, the number designation on a ND filter does not directly correlate the number of stops of light it reduces. Personally I think article your referenced (Neutral density filter) needs to be rewritten, as the chart provided is not absolute, and depending on the manufacturer of the filter the actual reduction in light can be different. —The preceding unsigned comment was added by Cnjackson (talk • contribs) 18:03, 2 May 2007 (UTC).

Combine with ND filter article

I suggest combining this article with the "ND filter" article. Both articles are rather small and cover the same topic, so they will benefit from the merge.Mikus (talk) 18:53, 22 July 2009 (UTC)
