Chromatic aberration occurs when a lens fails to focus all colors to the same point, causing blurriness and color halos. It can be corrected with achromatic lenses and is present in cameras, microscopes, and the human eye. It can be corrected in post-production, but may not be immediately noticeable. Other issues may also cause problems […]
Chromosomal aberrations are abnormalities in the structure or number of chromosomes that can cause serious birth defects. They can be diagnosed with a karyotype and are caused by problems during cell division or exposure to mutagens. Aberrations can be numerical or structural and can be passed on to offspring. Some can be identified during pregnancy […]
Light aberration is a shift in the apparent position of an object caused by the relative motion of the object and observer. The aberration of light affects the perceived positions of stars and planets for observers on Earth. James Bradley discovered that the observed shifts in the position of a star were due to the […]
Spherical aberration is a visual effect caused by light distortion passing through a spherical lens, degrading contrast and blurring details. It can be corrected by reducing aperture size or adjusting light waves. Correct calculations are necessary for correction. Special filters can create special effects. A spherical aberration is a visual effect caused by the distortion […]
