The LEE85 Filter System Discover Kit from LEE Filters is a great place to start to discover the potential of contrast control with a graduated neutral density filter. The kit begins with the highly versatile LEE85 System Filter Holder, which can be configured with 1, 2 or 3 filter slots using the included modular guide blocks, just like the larger LEE100 System Holder.
A 2-stop medium-graduated neutral density filter allows skies to be darkened for more dramatic landcapes and seascapes, without a hard demarcation line. The filter can be be positioned anywhere in the filter holder, allowing the transition to fall where it may be required.
Three adapter rings are included to mount on common filter thread sizes; additional rings are available in sizes from 37mm to 72mm.
