Hi,
maybe some of you using cokin filters in the past have an idea?
I am searching for a ND split filter like this hoya
http://www.hoyafilter.com/products/hoya/oef-08.html
but in form and shape like a square glass-plate, which is bigger in size than the diameter of the huge frontlens of the AFS 14-24/2.8. I need that for some special purpose, especially do dim the lights of cities in the valleys below, which you can see in my video here.
http://newswatch.nationalgeographic...tain-timelapse-a-soundgarden-of-night-lights/
when I am able to dim the city lights better I can show more sky (thats a nice application of a split ND filter). I have seen some astrophotographers in the past holding glassplate split ND filters in front of their wide angle lenses per hand just for the long exposures, but at that time I failed to take exact notes what they used.
thanks for any hints.
sincerely
christoph
