Photographic silver halide material is captured on rainy nights, by opening and closing a 4x5” sheet holder. The toxics and chemicals in the raindrops (that contains high levels of nitric and sulfuric acids) determine a 1:1 impression on the negative. The light pollution at a specific site colors of the background of the image.

Light, sound and toxic pollution are disrupting the biorhythm of humans, animals and insects. It disrupts natural patterns of (wild)life and ecosystems, harms biodiversity, and contributes to an increase in carbon dioxide in the atmosphere. Many species are affected by light pollution, including amphibians, birds, mammals, insects, moths, bats, frogs, turtles, and birds.

The acidity in acid rain can cause damage to plants, aquatic animals, infrastructure, and buildings. Acid rain is related to the release of sulfur dioxide and nitrogen oxides into the atmosphere caused by human activities such as burning fossil fuels, industrial manufacturing, oil refineries, the meat idustry, generation of electricity, and transport.

It's less like an object and more like the weather. In an object you can tell where the boundaries are, but in the weather it's impossible to say when something begins or ends.
