This Lee Grad set comes with three LEE medium neutral density filters: 0.3 - 1 Stop, 0.6 - 2 Stop and 0.9 - 3 Stop. Formulated with harder than usual grad lines which compensate for smaller sensor sizes, these filters have a medium-dark to light transition which allows selective adjustment of exposure across the frame without affecting colour balance. These filters are best suited to scenes where harsh light between foreground and sky can affect exposure levels and therefore detail. Some examples of where to use these filters would be on rooftops or peaks of mountains or sea-sky horizons. All of these filters have a new grip tab which increases the visible area and keeps finger-prints off the filter zone.
