By the definition of ISO is a measure of the level of the camera sensor sensitivity to light. The higher the ISO setting, the more sensitive we terhada sensor light.
To get a clear picture on our camera ISO setting (ASA in the case of photographic film), think about a bee community.
1.An ISO is a worker bee. If I set the camera at ISO 100, which means I have 100 worker bees.
2.And if my camera set at ISO 200 means I have 200 worker bees.
Is the duty of every worker bees collect the light coming through the lens of a camera and make a picture. If we use the identical lens and aperture together we set at f/3.5, but I set the ISO at 200 while your 100 (think again of worker bees), the picture had who would finish faster?
In broad outline:
1.When we increase the ISO setting from 100 to 200 (the aperture is always a constant - we lock the aperture at f/3.5 or through Aperture Priority mode - A or Av), we shorten the time needed in making a photo on our camera sensor by half (2 times faster), shutter speed of 1/125 to 1/250 sec.
2.As we add more ISO to 400, we cut back on the manufacture of the photo until half: 1/500 sec.
3.Whenever esksposur shorten as much as half, we call esksposur increase by 1 stop.
You can try this sense in the case of aperture, shutter speed we try to set constant at 1/125 (or via the Shutter Priority mode - S or Tv), and change-change your ISO setting in multiples of 2; missal from 100 to 200 to 400 ... etc., look at the amount of change your aperture.
