One page of notes (The Rule of Thirds: A Simple way to improve your images)

• Dividing the photo into thirds and lining the subject with one of the lines makes the photo look better because it's not centered. 
• The rule of thirds is about the lines! Not the rectangles you see on your photo. Don't pay attention to the rectangles!
• This rule is especially useful when taking pictures of horizons or landscape type of photo.
• When having a detailed sky, photographing the horizon under the third line strengthens the composition and brings out the sky.
• The closer you are to your subject, the harder it is to use the rule of thirds.
• Having your subject in the photo full body will make it so that you can aline their body with one of the lines.
• However, when taking the photo close up, it is a good idea to make the main focus of the portrait the eyes. Aline the eyes with the intersections of the lines
• If you put the subject's face on the top right third lines, the viewers will have more to look at
• Having the subject on the right side will cause some viewers to scan the whole image to get to the subject
• Some cameras provide the grid to use while taking photos
• Having a visual of the grid is better than having an idea of it in your head
• When editing your photo you may apply this rule when cropping.
• Training yourself to use the rule while shooting will help you open your mind to more rules
• This rule is not something that you have to use, but it is suggested for more attractive pictures
• The rue is not always a good idea to use. In some cases it maybe better to center your photo or use your own opinion to say where to place the subject
• Using the rule of thirds you have to reframe the scene
