The LEE85 ND 0.3 Medium Grad Filter from LEE Filters is compatible with a separately available LEE Filters LEE85 Filter Holder that is suitable for both film and digital photography with compact cameras, mirrorless cameras, and mirrorless lenses. This medium grad features a density of 0.3 and provides a 1-stop light reduction in selective areas. The LEE Grad ND filters are part clear, part neutral density, and make it possible to balance the light intensity in one part of a scene with another. This medium ND Grad features a medium-edged line of transition between dense and clear areas. Generally medium ND Grads are best used on images of with apparent but indistinctive horizons or lines between light and shadow, such as rooftops, mountains, or trees portruding into sky. The LEE85 graduated optical-quality resin filters measures 85mm by 115mm and are 2mm thick. The additional length allows for adjustment of the filter within the holder. They do not affect the overall colouration of the image. All LEE NDs are meticulously hand-dyed each filter represents up to an hour of skilled work, as they are dipped in and out of baths of dye and results continuously monitored. You can stack any number of NDs together with other filters, to customise your LEE filter setup for any lighting situation. A filter pouch is provided for storage and transport.
