Colorful temperature

video art

Colorful temperature is a characteristic of the course of the intensity of the radiation of a light source as a function of the wavelength in the optical range. In other words, the color temperature of a light source is essentially the temperature (in Kelvin) to which an absolutely black body must be heated in order for it, roughly speaking, to glow in the same way as this source.

For example:

paraffin candle - 2000K,
electric lamps 40-150 watts from 2400-2900K4
lighting at sunset - about 3000K;
studio photo lamps 500 watts - 3200;
daylight, sunlight 5500;
overcast - 7000;
blue sky - 10.

The most common films in amateur and professional photography are produced for the photographic concept of daylight - marked day light (5500K) and studio use marked tungsten (3200K).

If you shoot on daylight film under electric light, the white color will be rendered as a dense yellow, and all other colors will be shifted accordingly.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
