Shutter speed – Learning Activity 1.2

“Train your skills with manual settings using your DSLR camera with aperture, manual focus and shutter speed.
This task focuses on shutter speed.
Use an active environment, and capture two photo series.
1. Freeze the pictures – short shutter speed.
2. Create illusion of movement in the pictures – long shutter speed.

First of all, I was really unlucky last week, weather was gorgeous, but I was working all week, and there was no daylight left for me when I was finished in the evenings – that’s why I’ve had to do my tasks in a bit of a different order than intended.

Some technical terms explained:

– Shutter speed: How long the shutter remains open on a camera when taking a photo. The longer the shutter speed, the more light is allowed to get in to the sensor (or film on an analogue camera), the brighter/exposed the image gets.

– Aperture: In optics, aperture is a hole or an opening through which light travels.  The aperture of an optical system is the opening that determines the cone angle of a bundle of rays that come to a focus in the image plane.  If an aperture is wide, then un-collimated rays are admitted, resulting in a sharp focus only for rays with a certain focal length. This means that a wide aperture results in an image that is sharp around what the lens is focusing on and blurred otherwise. The aperture also determines how many of the incoming rays are actually admitted and thus how much light reaches the image plane (the narrower the aperture, the darker the image for a given exposure time).

– Manual Focus: In the field of photography, a manual focus camera is one in which the operator has to adjust the focus of the lens by hand. Before the advent of auto focus, all cameras had manually adjusted focusing.

– ISO: Refers to the sensitivity of light. ISO is a common short name for the International Organisation for Standardization.
The lower the ISO is, the less sensitive it is to light. The higher the ISO is, the more sensitive it is to light.

So, these pictures were taken one night in my photography room in my basement:

First five pictures shows short shutter speed (ss). As you can see, the longer the shutter speed gets, the more movement in the pictures.
Last five pictures, long shutter speed, creating an illusion of movement.

All pictures taken with a tripod – and the room had no natural light. Therefore, the high ISO value in most of the pictures.

Learning activity 1.1 to be added tomorrow.
