The purpose of the ND grad is to reduce the brightness of selected areas of the frame, balancing out the exposure throughout the image. 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 in its holder, assessing the effect through the viewfinder, until the correct point is reached.
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.
Because all LEE filters are handmade by skilled technicians, their quality is guaranteed.
