The Exposure Triangle: Three Part Photography Workshop

Do you have a hard time taking clear photos indoors or have washed out photos on a sunny day? Do you wish you could take your camera off the automatic setting? These three workshops will help you discover how the settings on your camera affects your images and will help you gain confidence with the technical side of Digital SLR photography.

These workshops are intended for beginner and intermediate users of DSLR cameras or digital point and shoot cameras which have a fully manual setting (i.e. a setting that allows you to change both shutter speed and f-stop). If your camera does not allow for adjusting these settings, you may still find these workshops interesting, however, you may not be able to apply all of the principles being taught to your own camera.

The workshops will cover:

Saturday, November 8, 2014 – ISO and Kelvin scale

Indoors or outdoors; sunny days or cloudy days; fluorescent lights, tungsten or halogen – each of these light sources has a different “colour” and provides different amounts of light. Your digital camera has two main methods to compensate for lighting extremes. The Kelvin scale compensates for different “colours” of light. The ISO (“film speed” in the old days) compensates for bright days and dark rooms. This section will teach you which settings to use for everything from a sunny day at the beach to a candle lit dinner.

Saturday, November 15, 2014 – Shutter speed

It’s a simple concept – how long the shutter is open – but knowing how it affects your photo is key in choosing the correct setting. This section will go over when it’s best to use fast or slow shutter speed. We’ll also explore how to use shutter speed to create interesting effects..
If you have a tripod, bring it with you for this class.

Saturday, November 22, 2014 – F-Stop/aperture and Depth of Field

You can use your f-stop to get that cool blurry background look that some folks call “bokeh.” You can use your f-stop to take better pictures at music shows, in dark rooms and outdoors at night. You can also set your f-stop to make sure everything in a landscape is in focus from the flowers at your feet to the mountains in the background. This section will cover the way that aperture affects your final image and how to control the part of the photo you want your viewers to look at.

Workshop leader bio:

_MG_1959_cropEsther Vincent was inspired by her father’s enthusiasm for photography when, at a very young age, he let her accompany him in his darkroom where he taught her the magic of manipulating light and shadow.

As a commercial photographer her focus is on portraits, events, journalism and archiving performance. Her photographs have been published in The Globe and Mail, The Toronto Star, Pearl Magazine, The Peterborough Examiner, Canadian Organic Grower and The Dance Current among others.

When shooting for herself she turns her eye on the weather and environment around Peterborough as well as urban life and culture. She uses her camera to reveal her iconoclastic vision.

  1. Hello Esther – I am a new user of a digital slr camera and keen to learn of your workshop. Unfortunately I am out of province for the first session, and concerned that I would be missing important basics. Do you think I could still benefit from attending the 2nd and 3rd, or should I wait for another time? Ann

    1. I think it would be fine to take the last two classes. I will do a short review at the beginning of the second class and there are handouts from the first that you can use to get up to speed.
