Sunlit subject shot on a digital camera set to ISO 100, exposed at f/8 at 1/400 second which is the same exposure value as f/16 for 1/100 second, the recommended "sunny 16" exposure In photography, the sunny 16 rule (also known as the sunny f /16 rule ) is a method of estimating correct daylight exposures without a light meter .
For daylight photography, there is a similar rule called the Sunny 16 rule. The basic rule is: "For astronomical photos of the Moon's surface, set aperture to f /11 and shutter speed to the [reciprocal of the] ISO film speed [or ISO setting]." [1] With ISO 100, the photographer should set the shutter speed to 1/100 or 1/125 second.
This allows the camera to use a longer exposure and/or a longer focal length lens or even be attached to some form of photographic telescope co-axial with the main telescope. Telescope focal plane photography. In this type of photography, the telescope itself is used as the "lens" collecting light for the film or CCD of the camera.
Field of view is the area of the inspection captured on the camera’s imager. The size of the field of view and the size of the camera’s imager directly affect the image resolution (one determining factor in accuracy). Working distance is the distance between the back of the lens and the target object.
Star trail photography on salt lake in Lut desert in Iran. A star trail is a type of photograph that uses long exposure times to capture diurnal circles, the apparent motion of stars in the night sky due to Earth's rotation. A star-trail photograph shows individual stars as streaks across the image, with longer exposures yielding longer arcs.
A star-trail photograph shows individual stars as streaks across the image, with longer exposures yielding longer arcs. Star trails over the ESO 3.6 m Telescope [ 2 ] A star trail photograph showing the apparent motion of stars around the north celestial pole ; Polaris is the bright star near the pole, just above the jet trail.
Some cameras provide options for fine-tuning settings such as sharpness and saturation, which may be referred to as "Styles" or "Films". Some cameras offer color-altering settings to do things such as make the photograph black-and-white or sepia, swap specific colors, or isolate colors.
Current cameras do not allow direct setting of EV, and cameras with automatic exposure control generally obviate the need for it. EV can nonetheless be helpful when used to transfer recommended exposure settings from an exposure meter (or table of recommended exposures) to an exposure calculator (or table of camera settings).
