ISO
ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain. Higher ISO settings are generally used in darker situations to get faster shutter speeds. For example an indoor sports event when you want to freeze the action in lower light. However the higher the ISO you choose the noisier shots you will get. I’ll illustrate this below with two enlargements of shots that I just took – the one on the left is taken at 100 ISO and the one of the right at 3200 ISO

(PHOTO IS FROM GOOGLE IMAGES)
As you can see, the photo demonstrates the difference from a low ISO, to high ISO. The picture on the left represents and clean and polished photo, where as the photo on the right is noisy. This is because when the ISO is too high, the image is more bright, and in this case if it doesn't match the setting, it washes out the colour from the photo, thus creating noise.
