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 vs. Shutter Speed. In photography, aperture (also called f-number) refers to the diameter of the aperture stop (the stop that determines the brightness in a photo at an image point). Shutter speed on the other hand, is the total amount of time the shutter of the camera is open.
