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.
Slowest Practical Shutter Speed for Handheld? I have never heard of the film speed rule but I have heard of the lens focal lengh rule. I use the focal lengh rule alot but I have had good results at 1/8 and 1/15 of a second. I do mostly portaits so I use a tripod 70% of the time.
