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.
Shutter Speed Values. Shutter speeds change as shown below. Choosing a shutter speed one step faster than the current shutter speed (by, for example, changing shutter speed from 1/60 s to 1/125 s) is referred to as âincreasing shutter speed by one stepâ and halves the amount of time the shutter is open.
