The color of night: Surface color perception under dim illuminations.
Several studies document rudimentary color vision under dim illumination. Here, hue perceptions of paper color samples were determined for a wide range of light levels, including very low light levels where rods alone mediate vision. The appearances of 24 paper color samples from the OSA Uniform Color Scales were gauged under successively dimmer illuminations from 10-0.0003 Lux. Triads of sampl...
متن کاملThe color of night: surface color categorization by color defective observers under dim illuminations.
People with normal trichromatic color vision experience variegated hue percepts under dim illuminations where only rod photoreceptors mediate vision. Here, hue perceptions were determined for persons with congenital color vision deficiencies over a wide range of light levels, including very low light levels where rods alone mediate vision. Deuteranomalous trichromats, deuteranopes and protanope...
متن کاملExercise attenuates the metabolic effects of dim light at night.
Most organisms display circadian rhythms that coordinate complex physiological and behavioral processes to optimize energy acquisition, storage, and expenditure. Disruptions to the circadian system with environmental manipulations such as nighttime light exposure alter metabolic energy homeostasis. Exercise is known to strengthen circadian rhythms and to prevent weight gain. Therefore, we hypot...
متن کاملThe Night-sky at the Calar Alto Observatory Ii: the Sky at the near Infrared
We present the characterization of additional properties of the night-sky at the Calar Alto observatory, following the study started in Sánchez et al. (2007), hereafter Paper I. We focus here on the night sky-brightness at the near-infrared, the telescope seeing, and the fraction of useful time at the observatory. For this study we have collected a large dataset comprising 7311 near-infrared im...
متن کاملThe Night-sky at the Calar Alto Observatory
We present a characterization of the main properties of the night-sky at the Calar Alto observatory for the time period between 2004 and 2007. We use optical spectrophotometric data, photometric calibrated images taken in moonless observing periods, together with the observing conditions regularly monitored at the observatory, such as atmospheric extinction and seeing. We derive, for the first ...
