Samsung Digital Camera, EXS30NB manual Iso, DON’T Forget Auto ISO

THE POCKET GUIDE TO THE SAMSUNG NX THE NX SYSTEM

ISO

The NX’s sensitivity to light can be altered to suit the conditions or left in auto for peace of mind

The ISO is a way of altering the camera’s sensitivity to light. The lower the number, the less sensitive the camera’s image sensor is and the longer the shutter speed needed to form a correctly exposed image. The higher the number, the greater the sensitivity and the shorter the shutter speed needed to expose an image correctly. In the past, as the ISO number increases, image quality decreases and ‘distortion’ appears as something called image ‘noise’ – an increase in coloured dots or ‘grain’ in the image mainly seen in shadow areas. However, sophisticated software within all NX cameras removes this ‘grain’, so now at even high ISO levels in low

16light situations, your images will have smooth tones, bright colours and virtually no grain.

It can be fun to get creative

and shoot high ISO images 17 even in brighter conditions

for effect, leaving the Noise Reduction option off to deliberately add grain.

If you’d prefer not to up the ISO, you could turn on the flash instead and use it as your main light source to illuminate your subject.

DON’T FORGET: AUTO ISO

Auto ISO mode will set the ideal ISO automatically so you can always get shake- and blur-free images.
