Set iso to 320 or what ever low iso and use exposure compensation -1, -2 stops. then adjust in PS or what ever process you use for exposure. It seems to lower the noise significantly. I know Doug got this from someone else here on the LUG. Also I noticed the latest firmware for the M8 seems to give lower noise for the higher iso speeds.
