Benro has launched Polaris, a quite remarkable tripod head. It’s electronic and smart, allowing you to shoot timelapse, track stars, focus stack, and much, much more. It seems so awesome that the backers have already pledged nearly $2 million, and the campaign isn’t even over yet. So, let’s see what’s so special about this revolutionary product.
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.
