Bottom photo taken with the same camera, but with additional wide angle lens. The effect of aberration is visible around the dark edges (especially on the right). LCA is defined as the "variation of the eye's focusing power for different wavelengths". [14] This chromatic difference varies from about 400 nm to 700 nm across the visible spectrum ...
Monochrome photography is photography where each position on an image can record and show a different amount of light , but not a different color . The majority of monochrome photographs produced today are black-and-white , either from a gelatin silver process , or as digital photography .
Averted vision works because there are virtually no rods (cells which detect dim light in black and white) in the fovea: a small area in the center of the eye. The fovea contains primarily cone cells, which serve as bright light and color detectors and are not as useful during the night. This situation results in a decrease in visual ...
The nystagmus and photo-aversion usually are present during the first months of life, and the prevalence of the disease is estimated to be 1 in 30,000 worldwide. [3] Since patients with RM have no cone function, they lack photopic vision, relying entirely on their rods and scotopic vision, [ 3 ] which is necessarily monochromatic.
A stereoscope presents 2D images of the same object from slightly different angles to the left eye and the right eye, allowing the viewer to reconstruct the original object via binocular disparity. When viewed with the proper vergence, an autostereogram does the same, the binocular disparity existing in adjacent parts of the repeating 2D patterns.
The dress was a viral phenomenon, which was either seen as blue and black or as white and gold. Its true colours were eventually confirmed to be blue and black. [2] Ebbinghaus illusion: The Ebbinghaus illusion, or Titchener circles, is an optical illusion of relative size perception. The two orange circles are exactly the same size; however ...

In film photography, monochrome is typically the use of black-and-white film. Originally, all photography was done in monochrome . Although color photography was possible even in the late 19th century, easily used color films, such as Kodachrome , were not available until the mid-1930s.
