If you want to use natural light in your photography, it’s important to understand the angle of the sun and how that will affect your composition. For example, for most of the day, the sun is directly overtop so your subject will be lit from above. A sunny day without clouds will result in more intense shadows, while a sky full of clouds will diffuse the sunlight so that the contrast of light on your subject is less harsh.
