The Series 9 Blender Plum 2 Filter from Formatt resemble traditional graduated filters except that they are colored on top with a gradual transition to more subtle color at the bottom. Traditional graduated filters transition somewhere in the middle of the filter.
A Blender Plum 2 filter delivers even more intense deep purple/red. It differs from a Graduated Magenta that produces a milder purplish/red tint.
Formatt square and rectangular filters are made from sheets of CR39 Resin sandwiched between two sheets of high-quality Schott glass. The reputation of Schott glass precedes itself and is world renowned. The dyes used are carefully manufactured and controlled and when sealed between the glass, become color consistent filter to filter. For the photographer/videographer/cinematographer, this means you can change filters from day to day or shot to shot knowing that your color consistency will be maintained.
