Higher and lower sensitivity



 Pictures taken at iso of 200 / 400 / 800 showing different amount of grain 200 (Less) 800 (more).  Generally higher values give less clarity and auto iso on my D7000 can be selected to limit at a higher value such as iso 800.  However reading the web suggests that the camera can give clear pictures up to 1600 in ideal conditions.  It lectures it has been suggested to me that the D7000 as a Nikon has a 'sweat spot' at iso 200 meaning that this is the clearest image although generally the lowest iso of 100 is thought to give greater clarity
