I recently acquired a 2nd hand CPL 77mm thread for my 72 mm lens. Thus, I bought a step up filter of 72-77mm.
I'm now thinking of getting ND filters, probably cokin or tian ya filters. There are some doubts with regard to purchasing ND filters. Hopefully experienced users might be able to help.
If i were to get a ND filter system holder, does it fit on my lens with a CPL 77mm mounted on it?
I realised there are 2 types of ND, gradual and distinct. Any advices on purchasing either of these? ND 2, 4, 8 each shows a stop difference. For landscape photography, users normally use which type of filters?
I would like to create a silky flow of waterflows, sea waves, waterfalls etc. Would it be possible if I mount ND2 and ND4 each covering the top and bottom to create similar effect as a whole piece of ND instead of those halves.
