Small eco-footprint living room light
Here is my animation.The device on my bicycle wheel is a S.W.I.M. stick driven by an accelerometer + micro-controller, displaying the gravity values in a range from -1 to +1.
There are three image composites to see.The first composite shows basic long exposures of lights moving a long a track. First image in the upper left is a single blue light, the image the right of it has a red light added to it, while the third image below it is of telegraph poles being lit by the two lights. You may notice that the blue and red light is not evenly distributed over the poles.The second composite image shows what happens in a scene where the subjects may respond differently to the light sources, depending on the correspondence of colours between the light sources and subjects. The first image in the upper left shows how the blue people brightly reflect the blue light, while the red people appear quite dark. Under the red light in the image to the right, the red people appear a little more bright than the blue people. The image below the two shows the whole scene in bright white light, so that you may see how the red and blue people for what they are.The last composite image explores how light and shadows can overlap to create quite complex patterns. The last image shows all of the "equipment" used, as well as my co-operative assistant. In all of the photos, the locomotive was carrying a forward pointing blue light. It was pulling a car to which was attached either a red or green light pointing backwards.
The first set of this series was used to determine the N value for my Canon Powershot S50.The next two composite images show the result of applying the N value for cementing 3 images into one.
So the first set is from the super-posimetric exercise of deriving the "n" value for my camera, while the second is a result of applying it to other images.
