FIVE THINGS TO LOOK OUT FOR …
A good filter system can turn snapshots into stunners. Here’s how to pick the right set-up for you
All our kits have square or rectangular filters. Round, screw-in alternatives can be cheaper, but they’ll only fit lenses of the same diameter and can’t be positioned to suit your composition.
NDs and ND grads are graded according to how much light they block, eg ND2 (one stop), ND4 (two stops) and ND8 (three stops).
Go for a kit with neutral density filters or ND grads and they should be just that: neutral. The darkened section shouldn’t introduce any noticeable colour cast to the final image.
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.
05 Size matters
Smaller P-size filters offer a good balance of portability and lens coverage, with 100mm-wide filters being a better match for FX D-SLRs. Smaller A-format kits suit compact system cameras.
