Project 2: ‘Layered, complex and mysterious…’
This section is all about daylight or what some call natural light.
In manual mode take a sequence of shots of a subject of your choosing at different times on a single day. Briefly describe the quality of light in each image.
I used my camera on a tripod to ensure that each image was taken from the same viewpoint to give consistency. I set the aperture (f/8) and ISO (400) as constants and at each point an image was captured I brought the camera’s light meter back to 0 (zero) by adjusting the shutter speed to ensure the exposure was consistent, according to the camera’s light meter.
The light started out quite blue. Sunrise on the day that I took these images was 07:23. The light became less blue as time passed. There was more light as the sun rose and the light moved to a warmer colour. Peaking at ‘golden hour’. Nearer sunset it moved back to blue tones. Sunset on this day was at 16:02.
Comparing the quality of light in these images is difficult as it depends on what look and feel you are trying to achieve in your images. The word quality implies that there is a time of the day where light is generally better for taking images.
With regards to the tone of light I think it depends on what you want to achieve as to which part of the day has the right quality you seek,
e.g. golden hour approx. 1 hour before sunset is a beautifully glowing experience and a brilliant time for taking images – here is one I took at just that time of the day:
Intensity/brightness is a quality of light but not in the sense that to have high intensity light is necessarily better or worse than not having it. The intensity of light might help facilitate a specific exposure setting to be achieved e.g. when a fast shutter speed is needed to freeze motion of a fast-moving subject, which also requires a deep depth of field.
For further information the start and end times for other light measures on this day in Gillingham, Kent were:
|Morning astronomical twilight||05:25||06:05|
|Morning nautical twilight||06:05||06:46|
|Morning civil twilight||06:46||07:23|
|Sunrise and sunset||07:23||16:02|
|Evening civil twilight||16:02||16:39|
|Evening nautical twilight||16:39||17:20|
|Evening astronomical twilight||17:20||18:00|
Twilight is the illumination of the Earth’s lower atmosphere when the Sun itself is not directly visible because it is below the horizon. Twilight is produced by sunlightscattering in the upper atmosphere, illuminating the lower atmosphere so that the surface of the Earth is neither completely lit nor completely dark. The word twilight is also used to denote the periods of time when this illumination occurs.
This completes my submission for Exercise 4.2, which concludes Project 2. Now on to Project 3 – ‘The beauty of artificial light’ and Exercise 4.3.
