Understanding the exposure triangle is fundamental to good photography. Tonight we will be refreshing our knowledge of the triangle – ISO, shutter speed and aperture. We will have a brief overview before three members look at each of the sides individually. Paul Shelley will take on ISO, hopefully telling us all what ISO actually stands for, what happens when you adjust it (from a technical perspective) and when to use auto-ISO. Peter Colbeck will explain similarly explain aperture. Colin Page will tackle shutter speed. All three will consider the technical aspects of their part of the triangle, but also how to use them to get the results they are trying to achieve, and how to use them creatively. The evening promises to be entertaining and informative and should appeal to all photographers of all levels…and encourage those who are still on ‘automatic’ to become more adventurous.
