These filters are used to make adjustments to the red, blue or green characteristics of light. Applications include correcting for color balance, light source variations, different reversal film batches, and other color effects. They are available in density variations of Cyan, Magenta, Yellow, as well as Red, Blue, and Green filters.
These filters can be combined to achieve more density. Screw-in sizes up to 82mm offer Magenta 30 only. Magenta filters balance the color of excess green cast and produce creative effects. Great for morning tint.
