A new camera system can take photos and videos of nature in the same colors that animals see. The system records in four color channels: blue, green, red, and UV. It then converts the data into “perceptual units” that replicate animal vision. 

The camera system uses a process called “linearization and transformation” to adjust and change the colors to match how animals see them. This process creates colors based on photoreceptor quantum catches, which is how many tiny particles of light (photons) are caught by cells in the eyes called photoreceptors. 

The new camera system can simultaneously record video in four color spectrums: UV, red, blue, and green. This is different from previous attempts to recreate the colors seen by animals, which used a method called spectrophotometry. This method was time-consuming and unable to capture moving images. 

The new camera system can help scientists better understand how different animals navigate their environments. For example, researchers used the new camera and software to replicate the photoreceptors in the eyes of various animals to see how they perceive the world differently

A George Mason University scientist and team of researchers developed a new camera system that allows ecologists and filmmakers to produce videos that accurately replicate the colors that different animals see in natural settings, according to a report in the open access journal PLOS Biology

Scientists have developed a camera system that can capture videos and photos of nature in the same colors that animals see. The system records in four color channels: blue, green, red, and UV.It then converts this data into “perceptual units” that replicate animal vision. 

The camera system uses a beam splitter to separate UV light from regular light. It then sends each to two independent cameras, which record all colors at the same time. 

The camera system also uses cutting-edge camera software to record and process videos under natural light conditions. This allows scientists to accurately represent what animals see.

A camera system can record video in four color channels: blue, green, red, and UV. The data is then processed into “perceptual units” using the programming language Python. This creates a more accurate video of how animals perceive those colors. 

The system is based on existing knowledge of the photoreceptors in animals’ eyes. When tested against traditional methods, the system was found to predict perceived colors with an accuracy of over 92%. 

The system can capture light simultaneously from four distinct wavelength regions. This allows viewers to easily swap cameras, lenses, or to visualize color appearance for a variety of animal viewers.

Animals have different types of color vision. Some animals have poor color vision, while others have excellent color vision. Some birds and bees can even see colors that humans can’t

The range of colors an animal can see depends on the combination of color-sensitive pigments in their eye and the processing by the brain. 

Humans use three cones to see in full color: red, blue, and green. However, cats and dogs only have blue and green cones. This means they have a much more muted perception of color, which is similar to color blindness in humans. 

Many mammals like cats, dogs, rabbits, cattle, sheep, and goats can only see a small amount of color. These animals are mostly dichromats (they can only see two colors) and may only see pastel shades of blue and yellow. 

Some animals see the world in just shades of blacks, whites, and greys. These include whales, sea lions, and some bat and mice species.

Many animals have different combinations of photoreceptors, which means that they see the world in their own distinct color palettes. A butterfly that looks pale yellow to us might appear entirely different to an avian observer

Here are some other ways human vision differs from animal vision:

• Field of vision Some animals have multiple eyes, which gives them a wider field of vision and allows them to see in different lighting conditions. 
• Eye size Some animals have much larger eyes than humans, such as the giant squid, which can have eyes up to 10 inches in diameter. 
• Tapetum lucidum Many animals have a special structure called the tapetum lucidum behind their retinas. This structure works like a mirror, allowing light to pass through the retina, hit the tapetum lucidum, and bounce back through the retina again. 
• Cone and rod receptors Humans have more cone receptors than rod receptors, while cats have more rod receptors than cone receptors. This is why humans can see colors better, but cats can see better at night. 
• Visual acuity Humans can see four to seven times more detail than dogs and cats, and more than 100 times more than a mouse or fruit fly. Humans with perfect eyesight are said to have 20/20 vision, meaning they can distinguish objects at a distance of 20 feet. Dogs typically have 20/75 vision, meaning they must be 20 feet from an object to see it as well as a human standing 75 feet away. 

Whereas human eyes contain three types of colour-detecting cells, called cones, dogs have just two. Their cone cells are specialised for picking up yellow and blue-to-ultraviolet light. Each cone type contains a pigment sensitive to particular wavelengths of light
