O que (quem) é exposure time - definição

LENGTH OF TIME WHEN THE FILM OR DIGITAL SENSOR INSIDE A CAMERA IS EXPOSED TO LIGHT
Exposure time; Exposure duration; Shutter speeds
  • Nikkormat EL]]
  • An extended exposure can also allow photographers to catch brief flashes of light, as seen here. Exposure time 15 seconds.
  • Different shutter speeds for a CPU fan. Shutter speeds from first to last: 2/1, 1/1, 1/10, 1/100, 1/200, 1/500, 1/1000, 1/2000, 1/4000
  • Images taken with a lower shutter speed evoke a visual sense of movement. Exposure time 3 seconds.
  • Shutter speed can have a dramatic impact on the appearance and quality of photographs, especially when moving objects are involved. For instance a slow shutter-speed often results in a blurred image as the slight shudder of the shutter itself, or the motion caused to the whole camera by the index pressing on the shutter-release button create vibrations that are faster than the shutter itself; this will cause the appearance of the objects in the view-finder and on the photographs having moved when in fact it is the camera that moved.
  • Sparklers moved in a circular motion with an exposure time of 4 seconds. This is an example of [[Light painting]].
  • 2000}} s
  • Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects.

Shutter speed         
In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter is open) when taking a photograph.
Radiation exposure         
  • Types of electromagnetic radiation
  • Linear graph
  • Dose quantities used in radiation protection
ELECTRIC CHARGE OF IONS PRODUCED IN AIR BY X- OR GAMMA RADIATION PER MASS OF AIR, WHEN ALL LIBERATED ELECTRONS ARE COMPLETELY STOPPED
Radioactive exposure; Radiation Exposure; User:Rwflammang/Sandbox; User:Rwflammang/Exposure (radiation); Draft:Exposure (radiation); Exposure (radiation); Exposure to nuclear radiation
Radiation is a moving form of energy, classified into ionizing and non-ionizing type. Ionizing radiation is further categorized into electromagnetic radiation (without matter) and particulate radiation (with matter).
double exposure         
  • Hand-coloured processed double exposure image of a woman in the Canton Region of Late Qing Dynasty, 1870s
  • Composer [[Karlheinz Stockhausen]], double exposure made using a film camera, 1980
  • Multiple exposure of one person, made using Adobe Photoshop
  • Double exposure made in the darkroom
  • Double exposure made using a film camera
  • An 1886 chronophotographic study of horse motion, by [[Etienne-Jules Marey]]
SUPERIMPOSITION OF TWO OR MORE EXPOSURES TO CREATE A SINGLE IMAGE
Double exposure (photography); Multi-Exposure; Multi Exposure; Double exposure; Multi exposure; Multi-exposure; Iskiography; Lothar Schiffler; Double-exposure
¦ noun the repeated exposure of a photographic plate or film to light.

Shutter speed

In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter is open) when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time. 1500 of a second will let half as much light in as 1250.

1. At 110 dBA, the maximum exposure time is one minute and 2' seconds.
2. According to the National Institute for Occupational Safety and Health, US, [1''8], the maximum exposure time at 85 dBA is 8 hours.
3. The Sun‘s light takes four hours to reach Pluto, and it is so gloomy that photographs will require a long exposure time. ‘That means we will not be able to speed too close to either Pluto or Charon, but keep a good distance – about 5,000 miles – so we don‘t blur the images,‘ added Bagenal.
