*Hydrocephalus facts medical author: Melissa Conrad StÃ¶ppler, MD. Hydrocephalus is a condition characterized by excessive accumulation of fluid in the brain. Hydrocephalus may be congenital or acquired. Communicating hydrocephalus occurs when cerebrospinal fluid (CSF) can still flow among the ventricles. Noncommunicating hydrocephalus, also called obstructive hydrocephalus, occurs when the flow of CSF is blocked. Hydrocephalus affects about 1 out of every 500 children. The most obvious indication of hydrocephalus in children and infants is often a rapid increase in head circumference or an unusually large head size.
Local color (visual art). From Wikipedia, the free encyclopedia. In painting, local color is the natural color of an object unmodified by adding light and shadow or any other distortion. Local color is best seen on a matte surface, due to it not being reflected, and therefore distorted. In fine art realism, local color is the color the brain perceives an object to be. For example, an apple is red.
Color temperature is conventionally stated in the unit of absolute temperature, the Kelvin, having the unit symbol K. Color temperatures over 5,000K are called cool colors (bluish white), while lower color temperatures (2,700â3,000 K) are called warm colors (yellowish white through red).hotographic film is made for specific light sources (most commonly daylight film and tungsten film), and used properly, will create a neutral color print. Matching the sensitivity of the film to the color temperature of the light source is one way to balance color.
