If you are 25-30, or right at the time that you are getting into home ownership, then your credit score is quite important. By the time you are 45 and have likely paid off your home (a good saver should have paid of their mortgage by this time) then what you said is more correct.
Letâs quickly review a summary of the Exposure Triangle as a refresher: 1  ISO â the level of sensitivity of your camera to available light. 2  Shutter Speed â the length of time a camera shutter is open to expose light into the camera sensor. 3  Aperture â a hole within a lens, through which light travels into the camera body.
In your camera's viewfinder, a shutter speed of 1/4 is displayed just as 4. A shutter speed of 4 seconds is displayed as 4  (with a double quotes afterward to indicate whole seconds). Shutter speed is the amount of time that the camera is permitting light from the lens to hit the film or digital sensor.
