Neutral Density Graduated Resin Filters
(100mm X 150mm) |
The purpose of the ND grad is to reduce the
brightness of selected areas of the frame.
Crucially, a true neutral density grad should
have no impact on colour balance, and this is
where LEE Filters’ ND grads excel.
Neutral density grads are available
in both hard
and soft 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.
A hard graduated filter is characterised by a
very sharp transition between the coated and
uncoated sections of the filter. A hard grad
allows the photographer to control with
great precision the desired effect on the
composition – especially when the transition
between two areas in the frame is
particularly abrupt, as with a clear horizon,
for example. The effect of the filter ‘carrying
over’ from one part of the frame to another
would be undesirable.
The transition between the coated and
uncoated portions of a soft graduated filter is
less sharp and more subtle than in a hard
grad. A soft grad is recommended when the
variation in light readings within a scene is
less pronounced, and on occasions when the
effect of a hard grad would be apparent in
the result, showing as a ‘line’ across the
composition. The transition in tones, from
bright to dark, should appear very natural
when using a soft grad. |

Neutral Density Standard Resin Filters
(100mm x 100mm - non-graduated) |
| The aim of the standard ND filter is to reduce
exposure equally across the entire frame. It is
most commonly used to lengthen shutter
speeds in order to blur the movement of, for
example, clouds, water, or even people. |

 |
Light Yellow 3
Partially corrects for
excess blue in aerial photography.
Approx exposure increase 0. |
|
|
 |
Yellow 8
Darkens sky, cloud and
foliage to reproduce correct tones.
Approx exposure increase +1/3 |
|
|
 |
Yellowish-Green 11
Used to alter the response

Deep Yellow 12
Minus blue filter. Can be used to
cancel blue light when infrared-sensitive films are
exposed. Also penetration of haze during aerial photography.
Approx exposure increase +1/3
|
|
|
 |
Deep Yellow 15
Increases contrast between cloud
and sky greater than No. 8, for over-correction effect.
Also used for copying documents on yellowed paper.
