When you are composing your photos one way to capture the attention of visitors, and lead that attention to something specific within a photo, is to make use of leading lines. These leading lines will guide interest and allow you to create some really powerful and intriguing photos.
Taking photos just before sunset allows you the opportunity to get a beautiful backlit effect. Backlit photos tend to work great with portraits, which makes the golden hour just before sunset a great time to shoot.
Silhouettes can create very interesting photos that grab the attention of viewers. Many silhouette photos are captured at sunset with a personal/people or outline of the landscape creating a powerful image.
The same scene will look drastically different when being photographed at night, as opposed to during the day. Night photographs can be very interesting and intriguing.
Animals and wildlife can be the subjects of amazing photos, but capturing that great shot can often prove to be quite difficult. Finding the wildlife is often a challenge in itself, and then once you find it you will need to be able to get the shot before the animal moves or runs/flies away.
Buildings and other types of architecture are all around us, and they can make excellent photography subjects. It could be the architecture in your own city, or unique architecture that you come across when traveling.
