Creating presentations What you already know but haven't had time to think about. Everyone has probably seen convoluted slide shows or unintelligible figures in journals, and hopefully everyone has seen or read something that got a complex idea across with what seemed effortless and simple. You know the difference between a good presentation and bad presentation because it is the same as the difference between an effective teacher and a poor teacher. A good place to gather presentation ideas is from going to talks, cruising the Net, flipping through journals and books in your field as well as other fields. Photographers scour magazines and newspapers to see what other photographers have done.
Interior designers go to other people's home to see what they've done.
Get an idea what others are doing. Figure out what you like. Pick and choose. Find an idea and run with it. Now that you know what is out there, visualize how the final product will look.
