IN THE FIELD Podcast #1-The exposure Triangle

Hello and welcome to the first edition of what I hope to be a recurring event.  Initially I will do 5 podcasts and based on the reaction, more may come.  The podcast is aimed and new and advanced amateurs.

I don’t use professional gear and one of my goals is to show you how you can get “pro” results without spending 7k on pro gear.  I believe with a sound knowledge of photography and an intimate knowledge of your equipment and its limitations you will be able to produce some amazing shots.

At this point I should introduce myself.  My name is Todd Williams and unfortunately I am currently based in Halifax, you may have noticed an accent, it’s not local.  I spend my days running sales for a panmedia marketing agency and nights playing with my two gorgeous daughters, any spare time is devoted to photography.

I will start with an inventory of the equipment I will be using in this series.  When not shooting film I use

  • Nikon D50
  • Nikon SB 600 Speed Light
  • Nikon F3.5-5.6AF-DX , 18-55mm
  • Nikon F4-5.6AF-G , 70-300mm
  • Nikon F1.8AF-D 50mm
  • Nikon F3.5-5.6G 28-80mm
  • 52mm Circular Polarizer
  • Tripod & Monopod

You can achieve similar results without a DSLR, but as you advance in your photography career you will find limitations in non dslr cameras that can only be rectified with the versatility of a dslr.

Enough on introductions, now let’s look at the exposure triangle.

Understanding the exposure triangle will let you handle any photographic situation.  The exposure triangle consists of ISO, Shutter Speed and Aperture.  There is a direct relationship between the three elements, ie the easiest way to properly expose a low light situation is to bump the ISO up.  When you do this you can step down the aperture and increase the shutter speed, or you could do the opposite, it depends on the depth of field and amount of light you wish to create.

Depending on your camera, if you increase the iso you will increase the amount of “noise” ie grain in the photograph, my D50 has excellent noise characteristics up to iso 1600.  Results will vary with your camera.

Now lets head out to the field:

I’ll use the example of changing the shutter speed.  In the two examples below iso and f stop are constant.  The first photograph is brighter because the lens was open longer and let more light in.  Which one is properly exposed?  That’s your personal preference. Photography is your personal interpretation of light, don’t let some old wanker determine your preferences, shoot for your own enjoyment first.  After all, most of it can be fixed in post production, but the whole point of DSLR ownership is to get it right in the camera.
