Lukkertid

Vi lærer om speilreflekskameraets hovedfunksjoner og startet med begrepet Lukkertid.
Gaute viser og beskriver det slik på bloggen sin:
"This assignment taught us more about the cameras more advanced options, namely Shutter Time.
With a quick shutter time, the picture is taken quickly, letting small amounts of light in, so one needs to increase the ISO and aperture. 

On this escalator you can see that the stairs look flowing, thats because the shutter speed is slow, almost like taking a bunch of pictures and layering them. the shutter speed was 6 seconds. 

This picture has a slow shutter speed too, 0.4 second. with the movement of the camera and the shutter speed, the cars headlights dance in the picture."
