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.
2. High-speed sync flash is used when you want to use a shutter speed that is faster than your cameraâs native flash sync speed, or when you want to use a wider aperture setting that requires a higher shutter speed as is often the case with outdoor daylight shooting.he flash instantaneously lights up the subject (it does travel at the speed of light), so the flash doesn't last nearly as long as the shutter remains open even though this is very fast (1/60s, 1/125s 1/250s, etc.). There is a limit to the shutter speed, and this is the cameraâs native sync.
