A truly dark sky has a surface brightness of 2 × 10 −4 cd m −2 or 21.8 mag arcsec −2. [9] [clarification needed] The peak surface brightness of the central region of the Orion Nebula is about 17 Mag/arcsec 2 (about 14 milli nits) and the outer bluish glow has a peak surface brightness of 21.3 Mag/arcsec 2 (about 0.27 millinits).

Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. [1] In other words, brightness is the perception elicited by the luminance of a visual target.
When seen from below by a predator, the animal's light helps to match its brightness and colour to the sea surface above. Counter-illumination is a method of active camouflage seen in marine animals such as firefly squid and midshipman fish, and in military prototypes, producing light to match their backgrounds in both brightness and wavelength.
Active camouflage is used in several groups of animals, including reptiles on land, and cephalopod molluscs and flatfish in the sea. Animals achieve active camouflage both by color change and (among marine animals such as squid) by counter-illumination, with the use of bioluminescence.
Animal-made art consists of works by non-human animals, that have been considered by humans to be artistic, including visual works, music, photography, and videography. Some of these are created naturally by animals, often as courtship displays , while others are created with human involvement.
The list is full of examples of this art style and movement that were created by artists from all around the world. So, check them out; maybe it will convince you to become a surrealism enthusiast.
Light Art is a fairly new construction, as a mirror translation from Dutch or German: Lichtkunst. The pioneers of light art, being devoted to it, felt the necessity to give it certain names in order to distinguish their art from any other genres of art like painting, sculpture or photography.
