Grey/ Gaffer Glass

[Christian Mario Löhr]

A while back I met a gaffer who had a gaffer glass made up of two pol filters. They could be rotated to any required density. I loved the flexibility it gave him and have since been looking to purchase one, but can't seem to find any information on them. Can anybody here point me in the right direction?

Cheers!

Variable Density Filter - Here's a Hoya (photography) - http://www.hoyafilter.com/hoya/products/ndfilters/variabledensityfilter/


There seems to be an issue with blue shifting color when using two polarizers - (maybe why the don't call it a Neutral filter).

Here's Schneider VND: https://www.schneideroptics.com/ecommerce/CatalogSubCategoryDisplay.aspx?CID=1859
They claim no blue shift.

77mm screw-in, duo (nd and pola), triple (nd, pola, color enhance)... or a single (just the vari ND .... 77 or 82)

stills based though, but sure it could work if using EOS mount

hey guys,
thanks for your reply, although the links are not quite what I'm looking for. I don't want to attach it to a camera. It's for gaffer and sparks work and is something along this line http://www.gaffersglass.com/, only that this example has a fixed density and I'm looking for a variable version. any ideas?

Christian,
I seem to remeber a specialty company here in Hollywood making custom viewing glass ... Let me investigate
