Re: Digital ND Filter?

The compacts mentioned have it more because of a lack of latitude afforded by the tiny sensor .

As for getting it on Nikon's radar , it is more likely to be looked at by Pentax who have shown themselves to be more innovative .

As for how to implement it - I would be looking either at DLP technology , similar to that used in data projectors ( where you have pixel sized mirrors that flip one way or the other when energised ) , or for a simpler solution look at an optical filter with a reactive variable density , which darkens as the sunlight increases in intensity , exactly as employed in some sunglasses ; this would simply be a filter put onto the lens as per any other filter , the only difference being the variable density - or has this already been done ?
With kind regards
