Neutral Density Filters

[Kayaker72]

I've been playing with square filters. If I were to limit myself to two, I'd probably go with a 2-stop hard edge graduated filter and a 3-stop reverse ND filter.

I don't find myself using the soft edge graduated filters as much.

I have three Cokin filters and two singh ray.

I also prefer square filters because you can use them as pure ND, gradual or both. This picture is taken with a ND2 and a ND8 (Cokin Z-Pro), 1,6" f/32 on a bright day.
