Shutter speed determines how long the camera's shutter stays open, allowing more or less light in. A longer shutter speed can blur motion while a shorter speed freezes action, provided there is enough light. ISO refers to the camera sensor's sensitivity, with higher ISO numbers increasing sensitivity to light but also adding more grain. Aperture is the size of the opening in the camera lens, with a larger aperture admitting more light.

2. Shutter Speed
Shutter speed is how fast the shutter on the camera
stays open for which determines how much light is let
in, Generally a longer shutter speed blurs the pictures
and a short shutter speed freezes the action and makes
the image clearer providing there is enough light.

3. ISO
ISO is how sensitive your camera
lense is to light, a higher ISO
increases the sensivity and a lower
decreases it. The disadvantage of
having a higher ISO is it adds grain to
the image also known as noise.
ISO numbers typically start at 100 and
double each time.
ISO 100
ISO 200
ISO 400
ISO 800
ISO 1600

4. Aperture
Aperture is the hole within the lens through which the light passes through much like the
human eye. The larger the hole the higher the aperture.
