These are the three camera settings that affect the photography exposure.
ISO speed- Film speed is a standaridised measure of the speed at which the film reacts to light.
•Use an ISO of 100 or 200 when taking photographs outside in sunny conditions.
•If the sky is overcast or it is evening time, then use an ISO within the range of 400 to 800.
•Night time or in cases of low light you might need to set your digital camera ISO to 1600. If you don't then your photo will appear too dark if at all.
SHUTTERSPEED- The precisely controlled time the shutter stays open during exposure- usually measured in fractions of a second.
In photography and digital photography the shutter speed is the unit of measurement which determines how long shutter remains open as the picture is taken. The slower the shutter speed, the longer the exposure time. The shutter speed and aperture together control the total amount of light reaching the sensor. Shutter speeds are expressed in seconds or fractions of a second. For example 2, 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000. Each speed increment halves the amount of light.
APERTURE- Is just another word for hole. Adjusting the size of the hole controls the intensity of te light passed by the lens. A device that controls the amount of light admitted through an opening. In photography and digital photography, aperture is the unit of measurement that defines the size of the opening in the lens that can be adjusted to control the amount of light reaching the film or digital sensor. The size of the aperture is measured in F-stop.
A very informative video!!!
