What is ISO?• ISO is the measurement of how sensitive a digital camera's
sensor is to light.
• The higher the ISO, the more sensitive the image sensor and therefore the possibility to take pictures in low-light situations..

ApertureAperture is the opening through which light travels towards the
sensor.

How To Use Aperture?• A large aperture (low f
number) allows more light to hit the sensor. That means that you can use a faster shutter speed, either to capture fast paced action, or to take photos in low light. In high light a small aperture decreases light and prevents over exposure.
• Changing the aperture, changes the depth of field. Depth of field is a distance where the subject appears sharp. Large aperture (low f number) has small depth of field. So if you want a tiny part of your scene to be in focus, use a large aperture.

Shutter Speed• A camera's shutter speed can control exposure, but it's also
one of the most powerful creative tools in photography. It can convey motion, freeze action, isolate subjects and smooth water etc…

Creative Shutter Speed

Your Task!!
• Create a series of photographs which illustrates the use of ISO, aperture and shutter speed in digital photography.
• A series of six photographs. Two contrasting photos for each element. E.g. for ISO you would shoot one image using a low ISO creating a fine grain image and another with a high ISO creating a grainy image.
• Using Photoshop present your images side by side in a single A4 or A3 image.
