The filters for the Seven5 system are manufactured to the same standards as those for the renowned 100mm system. Handmade in a way that meets the company’s exacting quality control in colour and optical flatness, products in the LEE Filters range have become the benchmark by which other systems are judged, and are the indispensable tools of many photographic professionals worldwide.
The Seven5 filters are not just cut down versions of the LEE 100mm System. In keeping with the smaller size the gradation zones have been adjusted to suit the smaller system. These changes have been made through extensive testing in conjunction with top landscape photographers.
The LEE Filters range of Neutral Density (ND) Graduated Filters enable the photographer to selectively adjust exposure across the frame without affecting colour balance.
They are almost an essential in modern landscape photography on both digital and film cameras and come in a range of strengths denoting the light stopping power of the filter.
Whatever format you shoot, ND Grads help cameras record scenes more like we see them – with a broad tonal range that's lost if not captured in the moment.
There is a place in landscape photography for both hard and soft grads. Which one you decide to use will depend mainly on the subject matter of your image.
As a general rule, a hard grad would be used for images containing a horizon, or any hard transition between the sky and the foreground - even with jagged or mountainous horizons, the exposure can be controlled far easier with a hard grad.
Soft grads perform best in woodland, mist, or interiors. Anywhere where there is no definite transition between sky and foreground, a soft grad will gently balance exposure across the image.
The most common use for a single ND grad would be to balance the exposure difference between the sky and the foreground in a landscape image, retaining the natural colours and detail without over-exposing and "burning out" parts of the image.
For example, when photographing a landscape in which the sky is much brighter than the foreground, placing the neutral density part of the filter onto the sky in the frame will reduce the sky exposure without affecting the foreground. This enables cloud detail to be kept correctly exposed in the picture, and avoids the "white out" effect caused by exposing for the foreground. Even with the advent of digital RAW capture and image manipulation, ND grads remain an important tool, as lost highlight detail (in the same way as a burnt out area in a transparency) cannot be recovered if above the maximum recording threshold.
