Colour Level 1, Assignment 1

Assignment 1 for Colour Level 1 looks at the relationship between ambient light and artificial light, ideally in the situation of sunset with the sun behind the camera. I had to make two attempts at this because the first attempt turned out to be an unsuitable sunset (totally cloudy) so I left half way through sunset. We were advised to start shooting 20 minutes before sunset, and photograph roughly every 2 minutes, and finish shooting 20 minutes after sunset. We were to keep aperture constant (f/11) and use ISO 100 setting, obviously using a tripod and preferably a cable release. I enjoyed this exercise. I don't get a whole lot of time for photography, most of it is slipped in between toddler naps and outings etc. So this was an hour to myself to go and take a set of photographs which I am fairly happy with.

I thought carefully about the scene, and chose to photograph a pedestrian bridge over the Brisbane river with the city in the background and the nice curving bridge leading the eye through the image. To get this I positioned myself on the William Jolly Bridge which is a lovely viewpoint over the city of Brisbane. The progression of light changes over a 40 minute period is fascinating. I managed to just capture the last light on the buildings, then just prior to sunset there is a certain grey feeling (fortunately a few boats went past at this time to maintain interest). Then as sunset arrives there is little change apart from shutter speeds getting longer and lights starting to come on first on the bridge, and then illuminated signs on the buildings start turning on. As the time after sunset increases the sky turns a beautiful deep blue and the ambient light becomes more obvious and fills parts of the frame with a lovely warmth.

Below are a dozen photographs of my chosen scene.

I like the effect enforced by the smallest aperture images - due to the longer shutter speeds the water has a smoother quality than the other photographs. However the building signs are somewhat burnt and blurred in these longer shutter speed images. The progression of light is lovely and I think well captured in this set of photos. Sunset was at 6:04pm and I note that only two of the twelve best photos were taken before this time - so waiting for the golden hour after sunset definitely appears true in this situation.
