Treating Images – Decision Diagram & Example

Often images are considered to illustrate a case study. And there different opinions as to whether or not the image by itself is of sufficient quality.

The following decision diagram helps you on whether or not an image is (partially) usable and how to treat it. Scroll further below to also find a concrete example



The image below is not particulary well shot but it contains usable elements. The parts that can be considered most distracting are the personal elements on the foreground and some elements in the background. So we will first “crop” the image.


The result of the cropped image is visible below. There is now more focus in the image yet it still contains some distracting elements. So we will now smartly position captions and callouts.


As a first step, we will add a caption to  mask some distracting foreground elements:


In the last step, we direct the focus of the beholder by making him/her see the specific elements we want to focus on. Although the image has not been enhanced visually, by a few simple editing tips, the VALUE of the image has increased dramatically.


Aerial View

Aerial photography is the taking of photographs of the ground from an elevated position, often one of the following:

  • Another building
  • Helicopter
  • Drones


The use of aerial views is strongly recommended but if not possible, it’s okay to use non-aerial views for historical imagery. Note that often “aerial views” can be obtained using Google Maps or Google Earth.

Care has to be taken to select a view where the central object is to be approached using a 30 degree angle.

Top-down imagery is not recommended:


The use of fish-eye camera’s resulting in distorted perspectives is not recommended.
