The 6.5 x 6.5" Black Movie Mist 1 Filter from Hitech provides reduction of highlights without a great loss of detail. Contrast remains unaffected while highlights are reduced. It's more subtle than Hitech's Clear Movie Mist filter but shadows are not lightened as much. This is an excellent filter to use for portraiture as well as indoor or outdoor photography when you want to add both mood and warmth to the shot.
The grade 1 Black Movie Mist filter is an excellent soft focus filter. It reduces your highlights but will not reduce contrast. Subtle details are softened - more so than the Clear Mist version of this filter although shadow areas remain dark.
The Hitech filter system is made by Formatt - an English company that is renowned for its high manufacturing standards and consistency of quality. Their CR39 resin is manufactured in large sheets that are oven cured. Their exclusive Absorbing Cell Technology absorbs color as opposed to other filters that are coated. Once cured, they are sliced up to create individual filters. In this way, maximum consistency is maintained from filter to filter. This becomes crucial when you wish to change filters either mid shoot or from day to day.
