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.
Aperture is how we describe the size of the opening that determines how much light can come into your lens (like an iris on your eye). Assuming two lenses have the same size opening, a wider aperture value (smaller f stop #) will let more light in than the same size lens with a larger minimum aperture value.
