three parts of this triangle are:<\/p>\n<ul>\n<li><strong>Shutter speed<\/strong> \u2013 How long the shutter stays open for the exposure,<\/li>\n<li><strong>Aperture<\/strong> \u2013 What size opening in the lens is made,<\/li>\n<li><strong>ISO<\/strong> \u2013 What the sensitivity the sensor is.<\/li>\n<\/ul>\n<p>Since most cameras these days have an \u201cAutomatic Everything\u201d mode, knowledge of the Exposure Triangle is usually not necessary to get a good exposure.\u00a0 Modern cameras choose the \u201cbest\u201d settings for each leg of the triangle and, more often than not, your picture is, as we say, properly exposed.<\/p>\n<p>The purpose of this manuscript is to describe the effects of each leg of the Exposure Triangle on the resulting photograph.\u00a0 These effects are broken down into<\/p>\n<ul>\n<li>The primary effects,<\/li>\n<li>The secondary effects, and<\/li>\n<li>The tertiary effect.<\/li>\n<\/ul>\n<p>Simply put, the primary effect of each leg of the exposure triangle is the exposure.\u00a0 Each leg can make the resulting image lighter or darker.\u00a0 The secondary effects of these legs are varied and, in my opinion, one of the more interesting aspects of the art of photography.\u00a0 The tertiary effects are, in my opinion, a nuisance.<\/p>\n<h2>This web site<\/h2>\n<p>The content of this website is a manuscript on The Exposure Triangle.
