My understanding is that the Bayer color filter array is attached quite directly to the sensor, underneath the microlens array. It's not a mechanically separate layer in the "sandwich" like the antialiasing and/or IR filters are. See for example: http://micro.magnet.fsu.edu/primer/digitalimaging/cmosimagesensors.html If the Pentax sensors are different, and you somehow managed to remove the color filters, I think you'd do OK shooting in raw. The dcraw software, for example, is capable of outputting a monochrome image without demosaicing. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
