The SW150 Mist Grad is used to introduce a misty effect to select areas of the frame.  The Mist Grad can be pulled down from the top of the filter to soften the sky and cancel out any unwanted detail.

The best way to achieve an authentic result is to use the filters at a time when you would normally expect to see mist - that is, in the early morning, and in spring or autumn.  Careful use of mist filters can inject a mood and atmosphere in a way that's convincing and creative.  This can be tricky to replicate on the computer in postproduction.

This filter is 150mm x 170mm.
