Digital BW, The Print

The sensors only measure intensity. To get color color filters are 
overlayed over the sensor and data processing is used to fill in the 
colors between the pixels of the same color. To measure full spectral 
intensity you would have to remove the filter array.

However, wouldn't it be nice if someone made a B&W digitical camera - 
then 6 megapixesls would rally be six megapixels. The processing would 
be minized since you would not need to worry much about white balance 
(could use a filter to do that).  A true B&W digital camera.
