Point, Line, Plane

Point

For my image focusing on "point," I took a picture of a door stopper. The original image is on the left, and the edited image is on the right. While editing, I added a colored layer underneath the image and then applied the "hard light" blending mode to the image. Then, I decreased the lightness of the image using the hue/saturation adjustments. 

Line

For my image focusing on "line," I took a close-up picture of an air vent. The original image is on the left, and the edited image is on the right. While editing, I decreased the hue and the lightness of the image, and increased the saturation.

Plane

For my image focusing on "plane," I took a picture of a table. The original image is on the left, and the edited image is on the right. While editing, I inverted the image, decreased the hue of the image, and increased the saturation.
