LEE Filters Seven5 Hard Edge Filter Set
This Graduated Neutral Density Filter Set includes the 0.3 (1-Stop), 0.6 (2-Stop), and 0.9 (3-Stop) hard edge filters, and a triple filter wrap made of soft microfiber.
These filters are rectangular in shape so that you, the photographer, have the ability to manipulate where the grad line falls within the frame. If you wish to have more skyline than foreground simply move the filter down within the holder. Moving the filter up within the holder will allow for more foreground than skyline, you have ultimate creative control!
A hard edge graduated filter is characterized by a very sharp transition between the clear and neutral density sections of the filter. A hard edge grad allows the photographer to control with great precision the desired effect of the image – especially when the transition between two areas in the frame is particularly abrupt, such as a flat horizon line over the ocean. The effect of the filter ‘carrying over’ from one part of the frame to another would be undesirable.
The purpose of the ND grad is to reduce the brightness of selected areas of the frame, balancing out the exposure throughout the frame. A true neutral density grad should have no impact on color balance, and because Lee filters are perfectly neutral, your images will be true to what you see in nature.
It is also possible to stack neutral density grad filters within the same holder, as long your filter holder is set up to hold more than one filter, this allows you to achieve a variety of effects. Don’t forget, neutral density graduated filters – as with most others in the LEE Filters range – are compatible with both digital and film photography.
Neutral density grads are available in both hard edge and soft edge versions, and in strengths of 0.3, 0.45, 0.6, 0.75 and 0.9. The 0.3 strength equals one stop, while each subsequent increment equals an additional half-stop. Therefore, if, for example, the sky in a scene were two-and-a-half stops brighter than the foreground, a 0.75 ND grad positioned across the sky without encroaching on the foreground would ensure an even exposure.
