GOlden Hour Light
Using Side Light & Rim Light
Setting up so that the sun is at a 90 degree angle from your lens can allow you to great side light. If your background is dark the subject will pop out from its surroundings. If you place the subject in front of the sun just you can get rim light highlighting the edges of the subject. If you stop down or increase the shutter speed to darken the subject even more, you can create a perfect silhouette.
Sometimes you may encounter a situation where the light is being blocked by clouds. This soft diffused light will allow you to capture evenly lit animals but may not necessarily always give you the "pop" of color that Golden Hour light provides. Another scenario that you may encounter are rays of light that may partially illuminate your subject such as an owl in a dense forest.
