Hi, I was wondering if anyone had any samples off solid ND filters for me to have a look. Ie., with and without the filter.

I have 2 B+W filters that I bought off eBay but have color casts. They are 2 stops and 6 stops.

I have read that the 10 stops certainly have casts (all of them) so yeah .. not sure if I have is suppose to or not. I shoot film of course, so I wondered how you guys use a ND filter? I am stumped. Maybe is it to shoot 50 speed film and use a cheaper lens so I can stop all the way down to f/22 or f/32?

Many thanks.
