Sunrise or sunset?
If you want to shoot during the golden hour, it is good to check when the sun rises or sets. You can do this by googling or by downloading an app. Useful apps are:
Will you be shooting on location? If so, leave on time so you arrive at your destination before the golden hour. Half an hour in advance is sufficient. This allows you to look around and explore the place and, who knows, you might see a scene, composition or place you like better than the one you originally thought of. Also, consider in what season you want to take the picture. For example, winter is great for taking a picture of the sunrise because you don't have to get out of bed as early and chances are you'll have beautiful fog. Summer, on the other hand, is perfect for photographing sunsets. The weather is beautiful, and you don't have to skip your meal to capture that pretty picture.
Shadow play
The light emitting from the sun during the golden hour is soft and not as bright. Softer light means you are able to look towards the sun without a lot of discomfort. In addition, you don't have to deal with harsh shadows. Because the light changes quickly, you do need to keep a close eye on your ISO settings. You may need to correct your settings from time to time. If there's a bit of cloudiness, light will be reflected. The reflected light produces beautiful colours! Without clouds, the colours are limited and your photo quickly becomes dull. Do you want some extra sparkle in your photos? Lens flares are beautiful during the golden hour. These flares occur because you have internal reflections in your lens. You can create flares by tilting your camera slightly or by using an UV filter.
