Closed form A closed form photo allows you to see the entire photo.
Closed Form The photographer zooms in so that the part of the object is off the page.
Linear Perspective Lines recede back to a vanishing point at the horizon line. They get closer and closer together as they go back into space. Using perspective in your photographs makes them have depth or go back into space.
Scale Objects of the same size look bigger when they are closer to you and smaller as they move into the background. Scale also gives depth to your photos.
Atmospheric(aerial) Perspective Means that objects in the background are cool colors and are hazy. Objects in the foreground are warmer with greater details and contrast.
