I’ve been at a scientific meeting recently and (again) was surprised of the disconnect that sometimes occurred between a speaker and the audience. If the listener (me) does not understand a complex subject that is explained, it is not solely on me! Don’t blame me that I could not follow your cluttered slides and your jumbled train of thought! Sure, sometimes I will be uninformed or not smart enough. But sometimes it is on you, dear speaker.
Explaining an easy concept complicatedly is easy. Explaining a complex concept concisely is artistry. And while I’ve set through many talks cluelessly, I admired the few speakers who mastered the art: The ones that make you feel clever just by listening. The ones that explain intricate science so well that you think you designed the experiments yourself. The ones that let you rediscover what they did and make it seem like what they are doing isn’t difficult after all.
Giving a good talk boils down to the same things that are important in photography: The subject needs to be clear. Leading lines are necessary to guide the viewer. Help them navigate the frame. Unimportant stuff is left out (and there is a lot of unimportant stuff). And everything left in has to support the main subject. Tell a story.
The following pictures do not follow these rules at all, but I hope my own talk did at least…
