Five things to look out for when choosing the best graduated neutral density filter
Round, screw-in grads may cost less than larger rectangular or square versions with a dedicated holder; however, they restrict positioning, will only fit lenses of the same filter thread diameter and could produce unwanted vignettes on wide-angle lenses.
A good neutral density filter should be just that: neutral. The grey section shouldn’t introduce any noticeable colour casts.
If you only buy one graduated neutral density filter, consider how you’ll use it. Too low a density and bright sections may still burn out, but restrict too much light and skies take on an overbearing, leaden appearance.
Most filters are now made from optical grade plastic, making them lighter and more shatter-resistant than glass alternatives. They are more prone to scratches, though, so handle with care.
Check to see what other filters (like polarisers or colour grad) different manufacturers offer before committing to one system.
