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.
1 If the focal length is 50mm, then, the minimum shutter speed would 1/50s (1/60s). ( 2 not the corrected focal length for the sensor size). 3  For the focal length of 250mm, then, the minimum shutter speed would be 1/250s. 4  Adapting this guide to modern DSLRs with sensors that are smaller than full frame sensors.
