According to semiotic theories by Jakob von Uexküll, each organism has its own Umwelt, that is, a limited reality it can perceive through its sense organs. We humans can only perceive a tiny fraction of Umgebung, the bigger reality or the absolute world (if there is such). For example, we humans cannot perceive magnetic force but it does indeed exist. Likewise, we cannot perceive spectrums outside the range visible by humans. The great part of the Umgebung cannot be perceived by us.
To make the invisible visible, I devised a new photographing technique. I took three or more shots and used only the red, green or blue channel of each shot and then merged them together. If nothing moves, the result would be a normal photograph. It, however, reveals hidden colors when there are moving objects in the image.
