    Plug your headphones into an amplifier connected to your computer or MP3 player and listen very carefully. (Don't worry, this is going somewhere.) Keep the volume down on your computer or MP3 player and then turn up the volume on the amplifier. You'll notice that while your music gets louder, noise (usually a gentle hissing sound) gets louder as well.

    This is not entirely dissimilar to the function of your ISO setting! Your digital camera's sensor only has one inherent sensitivity, which is its actual physical sensitivity to light hitting it. If a picture is too dark (as will happen with a too-slow shutter speed), then your digital camera can amplify the signal from the sensor, just as you can turn the volume up on your amplifier to make your music louder. The downside is, camera quan sát không dây just as with your music, amplifying the signal also increases the amount of noise (grain) in your photographs. So there is a trade-off: if you want faster shutter speeds, you'll have to increase your ISO ("turn up the volume"), at the cost of bringing out noise. We'll explore these trade-offs some more.
