Lighting is one of the most important aspects of photography. Here's one tip that can have a huge impact on the success of your photography:
Use soft and diffused light from an overcast sky on macro photography, outdoor portraits, autumn colors, glaciers, wildlife, pets, and flowers. The contrast is low and the colors of the subjects will really pop in this kind of light
Most people think a bright sun means great color. It's usually the opposite. Soft light means that the color is particularly saturated, such as in the accompanying Vermont scenes.
In autumn, if you find yourself shooting in bright sunlight, wait until a cloud covers the sun or until the sun goes below the horizon. Your pictures will be infinitely better.
