In Get the Basics, you'll get explanations and photos to build understanding. In Explore, you'll find additional online resources to learn more. It's important to review and learn from these resources also! You'll have opportunities to practice in Build Your Skills. Finally, answer the questions in Record Your Findings at the end of this topic, be sure to include information you learned from the Explore resources.
Get the Basics
When you look at a landscape, you’re used to seeing a level horizon. Even with your head tilted, your brain still registers the horizon as being level. It's just the way our brains are wired. The horizon should be horizontal (horizon – horizontal – get it?) This is true indoor as well. Floors and ceilings should be horizontal. When you see a photo with a tilted horizon, it doesn't look right.
Another thing to keep in mind with the horizon is the rule of thirds. You’ll want to place the level horizon one-third from the bottom of the photo if you want more sky or one-third from the top if you want more land or water. Here are examples of each.

Before shooting your own level horizon photos, learn more about why you need a level horizon at Photography Lesson - The Importance of Straight Horizons from About:

Build Your Skills
Shoot four or more pairs of photos. For the first photo in each pair, let the horizon tilt. For the second photo in each pair, concentrate on keeping a level horizon. Choose a variety of subjects: landscape with some sky, sky with some landscape, sky-horizon like a sunset or sunrise, and indoor with the floor or ceiling line showing.
Compare your level horizon photo pairs. Select FOUR pairs. Share your photo pairs with your teacher, and be prepared to discuss how they show what you’ve learned. Download your photos to a computer to keep them for the portfolio you’ll create in the end-of-course final project.
