Design gradients on a computer,
download them to this unit, and select
your efforts from a choice of presets in
the field.
In practice, this ND filter might resemble a
Cokin-style square filter and holder, in
front of the lens, but this filter substrate is
actually electronically able
to vary density
locally, perhaps using a technology like
LCD (and ensuring colour neutrality), so
that specific gradient forms may be
tailored.
A further advancement might allow
localised grad tints, too, for colour effects
such as the often-overused 'half tobacco'
grad that was done to death for sunsets in
the late 80s in Miami Vice and Top Gun
types of material.

You need a Spatial Light Modulator (SLM -
see link) - it's basically an LCD array of
addressable pixels which you can pass
light through. I did an electronics project
at university using one of these in the
80's, where I got to use the department's
very exciting Argon Ion laser, and write
BASIC code to put different patterns on the
SLM. |

I saw the title and thought this would be some method to keep me from hearing about Brady Quinn anymore. |

Eh? Never heard of such a person.
Someone you know personally? |
