The LEE Reverse ND has been specifically designed to give photographers full control over images shot at the beginning and end of the day. They have a stronger density in the centre of the filter, with a carefully designed transition zone that gives a natural, balanced exposure to the sky.
Many landscape photographers will testify that controlling exposure at sunrise or sunset can be tricky. The strength of the sun means the sky can appear blown out, and trying to adjust the exposure can leave other areas in the frame underexposed. The Reverse ND helps balance the exposure for dramatic sunrise and sunset images.
The filters come in 2, 3 or 4 stop densities (at the darkest filter area on the horizon line).
They are available in different sizes to fit each of the LEE Filter Systems.
