When taking a photograph, we want to accentuate the best parts of the scene, while making sure that our camera settings aren't adversely affecting the final image. In the field, we need to pay attention to the "dynamic range", which is the difference between light and dark areas of your shot. We might shoot a landscape on a particularly sunny day, and some of our images may appear "blown out" (or overly bright). To avoid this, we need to pay attention to our exposure settings. Below, we've outlined how to adapt to light sources and create great exposures, so that our subject looks as appealing as possible.
What is exposure in photography?
Every exposure depends on three parameters: shutter speed, ISO, and aperture. Essentially, these settings form a triangle, and each side of the triangle affects the others. To find the perfect triangle for your scene, each parameter must be adjusted until they are all in balance. In the past, point and shoot cameras had limited exposure settings, and you couldn't change the shutter speed or aperture, so you were forced to shoot daytime and flash photography. Today, you can adjust this figurative triangle to capture amazing sunsets, breakneck action shots, and late-night scenes. Let's break down the triangle's three sides:
