Read through text that you aim to lay out on a page. In your mind, determine what the main messages are in the text. Keep in mind that words already are being comprehended by readers using a basic principle of Gestalt theory --- association. Readers do not see words as a collection of individual letters, but as entire characters.
Group text together to give off a message of association, following the Gestalt law of proximity. Use paragraphs, text boxes and columns to achieve togetherness. Text should be encapsulated entirely into one space; avoid having any hanging text in an adjacent boxes or columns by cutting down the text so it fits or making the box or column larger.
Emphasize words, ideas or concepts in the document by visually separating that text from the rest with bolding, italics or color following the Gestalt law of anomaly. Or refocus readers' attention to a particular idea by putting into the middle of text a "pull" quote that has particular importance or value to the text.
Guide readers through the remaining ideas using spacial indicators such as uniform subheadings and bullet points. Following the Gestalt law of similarity, allow readers to make associations between subheads by giving them the same font size, color and indentation, or allow readers to understand a list of ideas as such by prefixing them with a bold bullet point.
Pay attention to the background when looking through the view finder of your camera. Gestalt visual theory points out that our brain often perceives two-dimensional things in close proximity as a unified group. This can serve as a useful technique for unifying objects in a frame, or is something to watch out for --- as Michael Fulks illustrates with a photo of a woman who looks like she has a branch going through her head, due to the proximity of the branch to her head.
Create or capture lines in the environment through the photo framing. According to the Gestalt concept of continuation, a person follows the visual path she perceives. Paths can be real --- such as capturing and framing a road winding up a mountain --- or paths can be created with proximity --- such as a group of children walking in single-file toward something, or the path of a leaf's edge. Drawing readers' eyes through a photo using a path will exercise their imagination about a particular place or meaning of the situation.
Frame a photo by using a grid in the camera view-finder or by dividing the space into a grid of virtual and horizontal tri-sects in your mind. Place the object of your attention not into the center of the photo, but into one of the intersections of the tri-sects, which will give your eyes somewhere to move as they look at the image. Gestalt theory is precipitated on the idea that people view the figure and ground as whole.
