So, we have to add one more constraint to the design process: consistency. Some visualization ideas might just not work given the overall context of the presentation, sorry.
In the design process, I always start with the most important slides that convey the heart of the message. Brainstorm, sketch these, and then freeze the look and feel of the entire presentation based on these few slides:
- Position of titles
- Type of images (cartoon, nature, vintage, people, color)
Think of your presentation as a movie that runs in the background, it is set in a time, a place. You pick them all, but stay inside the world of your presentation.
