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.
An Explanation of Shutter Speed. Shutter Speed refers to the amount of time the shutter is open. This is usually measured in fractions of a second, a 'normal' (hate that word!) shutter speed would be around 1/125th of a second with a standard lens or mid-range zoom lens on the camera.
