In the narrow streets of Paris, we moved between light and shadow. We created two pieces reflecting different aspects of light and shadow in space.

In our first sketch, we (mis)used Photoshop by pulling the “shadow” value on a series of photos up to 100%. By doing this we radically increasing the contrast of the images and experimented with the affordances of commercial design software.

In our second sketch, we showed shadows’ ephemerality through a collection of ellipses, and their contrasting relationship to the “real” — represented by particles with simulated mass and force.
