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.
The aperture of a lens is the opening in the diaphragm that controls how much light is allowed to reach your focal plane (film or sensor). The aperture is usually rated as a fraction of the focal length, hence the f/x.y nomenclature. The wider an aperture is, the more light it allows through, and the smaller the number under f/ is.
