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 best way to understand aperture is to think of it as the controls for the pupil of an eye â the wider it gets, the more light it lets in. Together, the aperture, shutter speed and ISO produce an exposure. The diameter of the aperture changes, allowing more or less light onto the sensor depending on the situation.
