Assigment 2A

This week we were taught the uses of the Aperture and the Shutter Speed for taking pictures. They are also interdependent, as in, when one gets bigger, the other becomes smaller to complement the light coming into the camera.

Like 'The Fan' below, to capture a motion blur, the shutter speed has to be slow. While to freeze an action like freezing the rain drops in 'Droplets', we just need to increase the shutter speed.

The Fan

Motion Blur

Aperture: f/7.1 Shutter Speed: 1/4 sec ISO: 200 Focal Length: 35.0 mm

Droplets

Freeze Action

Aperture: f/5.6 Shutter Speed: 1/200 sec ISO: 800 Focal Length: 85.0 mm

Regarding the use of apertures, the size of aperture depicts the depth of field of the image. For example, a wider aperture would give rise to a shallow depth of field, such as the one in the first 'The Orchid (I)' image. On the other hand, a smaller aperture would lead to a deeper depth of field, showing a much sharper image at the background. 'The Orchid (II)' is one such example.

The Orchid (I)

Shallow Depth of Field

Aperture: f/5.6 Shutter Speed: 1/80 sec ISO: 800 Focal Length: 66.0 mm

The Orchid (II)

Deep Depth of Field

Aperture: f/20 Shutter Speed: 1/6 sec ISO: 800 Focal Length: 66/0 mm
