Taking whatever bands they use, or somewhat altered ones if that works better, why not let each sensor have more light? xyz causes confusion, We cannot use abc or pqr since those each have a letter overlapping rgb. Call my suggestion ijk i is r+g j gets all of rgb; it is just white k is g+b Use an ijjk pattern where rggb would be. If r, g and b have equal amplitudes, this lets 7/3 as much light through to the sensor. Even if you just use the middle jj's for monochrome, you get 4/3 the light at half the resolution. -- 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.
