That's true of almost every DSLR I know of. The only exception would be for sensors with analog gain stages between the CCD and the A-to-D converter which could have separate gain for the different colours. In practice this would have to be a sensor with four-channel readout; the noise introduced by switching the gain for every pixel would be prohibitive. There was speculation that the high-end Nikons could do this, but I'm not sure if it was ever confirmed. -- 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.
