The Lee Filters resin filter range includes colour effect, graduated, striped and special effect filters, available in either economically packaged boxed sets or as single items. The Lee Filters resins are made from lightweight, optically correct polymeric materials, which are tough, easy to handle and can be wiped clean. Every filter is individually hand made by skilled technicians and is then passed through a rigorous quality control system to ensure 100% accuracy and consistency.Graduated filters feature an area of colour at one end of the resin, with the opposite end remaining clear. This enables the colour or effect to be placed in a specific area of the frame by the positioning of the filter either up or down in the holder. The transition from colour to clear can be either fast (hard grad) or slow (soft grad).
