Our vision is our most acute and dominant sense. It helps us process and recall information quickly. When you're explaining a concept with pictures, it is more appealing and effective to your audience, therefore, we should combine good pictures with minimum words ( good, and explanatory ) to make an impact.
In visual storytelling you can keep your watcher/reader's interests alive by making good use of colour, texture, perspective and composition, graphics. For example, stop-motion, people are attracted to things that change pace and keep focused.
Coming across this new knowledge , we should try and use it in our future presentations and use minimum text and more images! :D
