Kodak has anounced a new colour filter that is supposed to be twice as sensitive to light. This means is that you will be able to take great photos in even darker conditions than you can presently. You can go pretty dark as itáis, butátypically you need to either keep the shutter open for longer (forcing you to use a tripod) or you need to up the ISO making photo grainy.
It is set to start appearing in some camerasáas soon asá2008. I’m not sure how it will be incorporated into other brands like Nikon (which I use).
