Filters, such a useful tool for allowing more control over your exposure. Some things are simply can’t be done with a camera alone. But with so many manufactures, types, and price differences buying a filter might get a little confusing.
While it would be nearly impossible to test every filter around. I did manage to assemble a decent collection in the hope to see the differences between cheap, expensive, square, screw-in and variable NV filters.
As you can see I have a mixture of square and circle ND filters that are 10stop in strength. I also added two 6stop filters and variable ND into the mix.
