Project Space and Light. Exercise 18 How Space Changes with Light.

What: The brief of this exercise was to visit one or two locations where I could return a number of times in different lighting and photograph on each occasion.

Where: Work

When: First thing in the morning as soon as the sun had risen and at the end of the day after the sun had set.

How: I had made note of these locations as viable locations as I was easily able to revisit these locations a number of times during the day and easily photograph the conditions.

The only slight problem I had with these locations are that I was unable to setup a tripod due to the space restrictions and the ability to transport a lot of equipment across the site to these places.

In the first location I really wanted to capture the difference in lighting conditions as although there was only a little difference in shadow there was a vast difference in the colouration of the light within the space.

During the day a lot of light comes in through the room which is then supplemented with the large lights around the roof of the workshop. When the sun sets the shapes in the roof supports are clearer and better defined but the shadows are coloured by the artificial lights giving them a yellow tint.

The floor also takes on the yellow tint making it more orange than in natural light.

I was surprised to find that I only had to half my shutter speed at the end of the day to capture the final image of the workshop. Even though I was in a slight different position, I can easily compare the light conditions and the shadows, the space looses height as it has lost the brightness from the skylights and I feel that the walls are slightly closer as they are not reflecting the light back into the workshop area.

I decided to revisit the link bridge to capture the differences in light even on a dull day. As the bridge runs east/west it captures a lot of light during the day and a lot of the shadows are completely lost in the brightness. Nearest the camera there is a small spot of shadow created by the building behind the bridge which blocks the sun coming in from the left hand side of the camera.

In the evening the bridge loses a lot of light as the darkness below and to the sides of the bridge creates a dark tunnel around the space and it spaces the space into a tunnel rather than a bridge. The inside of the bridge is light up by the small lights in the roof, as the main purpose of the bridge is to allow movement from A to B it is not covered in lots of light as a lot of light is not really needed, enough light is required to allow people to see where they are going and that is it.

There are small shadows created behind the supports of the bridge as they are thrown into relief by the roof lights.

I was surprised to find out how much light was lost as the shutter speed dropped from 1000^th of a second down to a 45^th of a second. I had expected the lights in the roof to produce much more light that what they actually did.

When I was at the bridge in the morning I took a modified camera which allows me to capture a colour Infra Red photograph, as an experiment to see if I could capture a completely different point of view on the lighting conditions of the space.

In the image I was able to capture a lot of repeating shadows which did not show up on the colour images. It also cast the other end of the link bridge into complete darkness making it a much sinister image, partially due to the image compression as I used the smallest focal length on a telephoto lens.

I am pleased to see that I was able to meet the brief and show that these areas changed with the lighting conditions.
