THE POCKET GUIDE TO THE SAMSUNG NXTHE NX SYSTEM
30
EVF (ELECTRONIC VIEWFINDER)
This is an optional accessory for
some NX models that attaches
to the Smart Shoe giving you the
choice to compose on the display
or the EVF. You’d use this when you
can’t see the display clearly in very
bright sunshine or to save on battery
power.
IMAGE SENSOR This is the part of
the camera that turns light into an
image. The sensor sits behind the
lens and is a grid of tiny photocells,
14.6 million to be precise. The image
sensor in NX cameras is the same
size as in most digital SLR cameras
so produces excellent quality images.
COLOUR CAST Every light source
we encounter, whether natural or
man made, emits a coloured hue that
the human brain, and the NX’s auto
white balance function, automatically
counterbalances. These casts are
managed and corrected via the
white balance function (see page 22)
on digital cameras.
NOISE/GRAIN As the ISO number
increases, from 100 to 6400, image
quality decreases and ‘distortion’
appears in the picture as something
called image ‘noise’ – an increase
in coloured dots or what looks like
‘grain’ into the image that can mainly
be seen in shadow areas. It can be
used for creative eect or removed
by the camera with High ISO Noise
Reduction software that’s built-in,
found via the Menu.
CAMERA SHAKE AND OIS In low
light shooting situations it is possible
to get blurry images from something
called camera shake. It’s caused
when the shutter stays open longer
to allow enough light in to expose
the image correctly. To help prevent
this, NX cameras have something
called an Optical Image Stabilizer
(OIS), an automatic feature built into
the lenses to help counteract tiny
movements when handholding.
