LEE Filters SW150 0.9 150x170 Graduated Neutral Density Hard Edge Filter
This filter will reduce the exposure in the top part of the frame by 3 f-stops. The 3-stop hard edge grad is the most popular hard edge graduated ND filter. If you’re looking for the perfect seascape shot over the ocean this is the filter to use. This filter will create dramatic skies for shooting on bright sunny days or over any distinct horizon line, as it will even out exposure and bring out the rich blue color of the sky! This filter is a must have for any landscape photographer. 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!
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.
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.
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.
A neutral density grad should be positioned at the point where the brightest area of the frame meets the darker area. This is achieved simply by sliding the filter up and down within the holder, assessing the effect through the viewfinder, until the correct point is reached.
Neutral density grads are available in Very Hard Edge, Hard Edge, Medium Edge and Soft Edge versions, and in strengths of 0.3, 0.45, 0.6, 0.75, 0.9 and 1.2. 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.
Resin Filters are made from lightweight, optically correct polymeric materials. This ensures they are durable, easy to handle – and can be wiped clean if sprayed by sea or sand during a shoot.
