Understanding About ISO Sensitivity in simple ways
The ISO (International Standards Organization) determines the
sensitivity of the sensor in camera. ISO determine the exposure of a photo,
along with aperture and shutter speed.

| Camera 3 main Features The iso rating typically rangs start from 25 ,50, 100 to continues to double from this point: : 100, 200, 400, 800, 1600, 3200, 64,000, etc.  |
ISO
Speed vs motion Blur
The lower ISO rating means ,this producing a smoother,
cleaner image.
The lower the ISO rating, the less sensitive the image
sensor is and therefore the smoother the image, because there is less digital
noise in the image.
The higher ISO rating means, thus producing “rougher” or
grainier images.
Iso sensitivity And images Noise
The
higher the ISO rating (more sensitive) the stronger the image sensor. which
thereby produces more digital noise.
The
lower the ISO rating (less sensitive), which thereby produces less digital
noise.
So
what is digital noise? It is any light signal that does not originate from the
subject, therefore it creates random color in an image.
Image Quality
Image
Quality is important to remember that the lower the ISO rating the better the
image quality.
Lower
ISO images will
be more color-accurate images and
smoother. ISO between 100 and 200 will
give you the best results, and depending on the image sensor
