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.
You set the Aperture and the camera can determine a Shutter speed and the ISO needed to get a good exposure. 1  Manual (M): If you want control over depth of field and the way movement is captured use this mode. 2  You set the Shutter speed, Aperture and ISO. 3  Don't forget to use the Exposure meter to check your exposure.
