Shutter SpeedThe shutter speed is a measurement of how long the camera is allowing light to enter it to make a picture. Shutter speeds are measured in fractions of a second, so a shutter speed of 60 would be one sixtieth of a second.
Take a photo of a race car traveling at 200mph. With a shutter speed of 60, you'll see a blur, but not much of a car. With a shutter speed of 500, you'll get a sharper photo of the car. With a shutter speed of 1000, you'll get a car that is clear and frozen in time. The faster the shutter speed the sharper the image! |
ISOISO is the sensitivity of the cameras image sensor. ISO settings are often rated at 100, 200, or 400 but go as high as 800, 1600,
and even 3200 on some advanced models. In a bright scene you would use a lower ISO because you will want less light in the cameras sensor. |
ApertureAperture is how much of your photo is in focus. The smaller
the aperture, the more your depth of field. In other words, everything in the background will be in focus too. Sometimes, you don't want the background in focus, so you have a higher aperture setting. |
