If you are serious about your photography and want to understand the basics of shutter speed, aperture and, ISO – this one is for you!
Good morning everyone! Today we are kicking off the day with a little camera basics video by Toronto-based photographer, Peter McKinnon. We have a variety of readers on the blog, some of you have been in the photography game for some time, others are just starting out (or just starting to build a real interest). So we thought, getting down to some basics about shutter speed, aperture and ISO isn’t a bad idea.
You might have heard about these before, hopefully, you have anyway. Sure, you can shoot on auto and let the camera basically think for you. But trust me when I say, understanding shutter speed, aperture, and ISO will make a WORLD of difference in your photography.
What each element means:
Aperture – Basically it’s the size of the hole (or opening) in your lens when you take a picture. The bigger the hole, the more light passes through to the sensor. This is also what controls the depth of field in your picture. Aperture is typically expressed in “f” numbers, for example, f/1.4, f/2.0, f/2.8, f/4.0, f/5.6, f/8.0.
ISO – This is the measure of your camera sensor’s sensitivity to light. With a lower number, for example, 100 you will have less sensitivity to light. With a higher number, for example, 1600 you will have more sensitivity to light. It’s important to remember that higher numbers can cause grain or noise in your image.
Shutter Speed – In short, shutter speed controls how long your shutter stays open. In other words how much light comes through to the sensor. The longer the time, the more light will hit the surface. Shutter speed also controls motion, so if you want to freeze motion you will have a faster shutter speed. If you wanted to get movement in your image you will have a slower shutter speed. Shutter speeds are expressed in a fraction of a second 1/15 (1/15th of a second), 1/30, 1/60, 1/125.
But let’s head on over to Peter and let him explain…
