[1] In simplest terms, bright sun = f:16 @ 1/film-speed-number (aperture and shutter speed, respectively). For example: On a sunny day at ISO 100 ("100 speed film"), the aperture is set to f /16 and the shutter speed (i.e. exposure time) to 1 / 100 or 1 / 125 [ 2 ] seconds (on some cameras 1 / 125 second is the closest ...
The sun may too bright and too powerful for us to look at with the naked eye, even from nearly 92 million miles away on Earth, but a solar orbiter recently got an unprecedented up-close glimpse of ...

On Earth, sunlight is scattered and filtered through Earth's atmosphere as daylight when the Sun is above the horizon. When direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat (atmospheric). When blocked by clouds or reflected off other objects, sunlight is diffused.
Two sun dogs often flank the Sun within a 22° halo. The sun dog is a member of the family of halos caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun ...
The character of the lighting is determined by the sun's altitude, and the time for the sun to move from the horizon to a specified altitude depends on a location's latitude and the time of year. [4] In Los Angeles, California, at an hour after sunrise or an hour before sunset, the sun has an altitude of about 10–12°. [5]
A plage / p l eɪ dʒ / is a bright region in the Sun's chromosphere, typically found in and around active regions. Historically, they have been referred to as bright flocculi, in contrast to dark flocculi, and as chromospheric faculae, in contrast to photospheric faculae. [1]
Sea otter and sun glitter Sun glitter Sun glitter (blue arrows) in Punga Mare (central black outline) Sun glitter is a bright, sparkling light formed when sunlight reflects from water waves. The waves may be caused by natural movement of the water, or by the movement of birds or animals in the water.
