Lee 4x6" Mist Stripe Resin Filter - This filter can be used individually or in combinations to create varying densities of mist and fog.
The stripe can often be used to cover the foreground of the shot, providing a feeling of depth of fog, while the clear center allows the viewers eye to be taken straight to the all-important subject.
