ISO and shutter speed
  This two things were which I had learned about the Nikon D7OOO camera on my first class. In digital photography, ISO measures the sensitivity of the image sensor, if younselect the high numbers of your ISO, your sensor will be more sensitve to light which allow you take images in a darker environment, I can choose the appropriate ISO on my camera to take images, and different ISO will make differnet impact on your images.
  Another important thing on camera is shutter speed, it can have a dramatic impact on the appearance and quality of your images, especilly when moving objects are involved, very short shutter speed can be used to freeze fast-moving subjects, for instance, when you are taking images at sports events, very long shutter speed are ued to intentionally blur a moving subject to effect, there are different shutte speed on the camera, for example, there are shutter speed on 1/30s, 1/60s, 1/250s, 1/2000s and 1/3200s, just like ISO, you should choose the most suitable shutter speed when you take photographs.
