*Freebie Photography 101, the Exposure Trifecta Part 1 : Aperture

exposure trifecta aperture part 1

Welcome to a new series on the blog, FREEBIE PHOTOGRAPHY 101 where we will explore both technical and artistic aspects of photography and our cameras.  The aim with the Exposure Trifecta (the relationship between Aperture, Shutter Speed and ISO value) is to learn how to better understand and control our exposure manually through examples and exercises to gain a better grasp on some of the seemingly daunting exposure modes and tools involved.  I’ll add articles about metering, exposure compensation, white balance and other often automated, yet powerful to understand settings that our cameras provide us the ability to control as time goes on as well.  It doesn’t matter if you’re shooting with a phone camera or a fifty thousand dollar medium format machine, understanding how an exposure is created, how a camera works while perhaps overwhelming at first, is easy, it really is.  With just a little time and effort, you’ll be understanding the hows and whys of different photographic effects and how to apply them in different situations.

When starting this blog 5 years ago, I did it to help friends and family who were interested in photography, to share techniques, and help answer questions I’d field to better understand basic photographic principals.  The site has grown and evolved into what you see today, chalk full of camera, lens and software reviews, gear-centric comparison pieces, lighting explanations or post processing tutorials, travel ramblings and editorial articles for the design collective I work with.

As is the cyclical nature of life, I’ve recently been having more and more conversations lately with friends and friends of friends who have shown interest in better understanding these powerful image creation tools and I thought it would be a good opportunity to refresh my original Exposure Trifecta article, written over 5 years ago.  Getting back to the roots as it were, and perhaps act as an introduction to some new friends we’ve gathered along the way here on the site.  So, grab your camera and a cup of coffee, we’re gonna have some fun.

If you feel like you could use a refresher, would like to add your input, or know someone just starting out or looking to better understand the Exposure Trifecta of Aperture, Shutter Speed and ISO sensitivity, come one, come all.  Through my amazing ability to ramble on, and the community we’ve built through this site, we’ll get you sorted and knowing how, and when to adjust these exposure variables to understand how to completely control your photographic vision.

*How do aperture and focal length affect the DOF or exposure on different sized sensors?

Okay, much like the “effective focal length” discussions, there seem to be many “effective aperture” discussions going around as many of these mirrorless interchangeable lens compact system cameras begin to really round out their lens offerings.  Well, I guess the micro 4/3 system has while the Samsung NX is getting there and Sony NEX system users still have a small handful of options, but not really here nor there.  The fact that so many lenses can be adapted across various formats can complicate the discussion.  Along with those who shoot with APS-C DSLR cameras, all references for focal length and depth of field seem to fall back to a full frame/35mm sized sensor as the benchmark.  There are some misconceptions as to how the aperture, or focal length affects the exposure or depth of field in these varying formats.

C’mon in, we’ll straighten this all out.
