I'm 2/3 through Daniel Park's surprisingly excellent book Camtasia 5: The Definitive Guide and have found more than enough I didn't know and am glad to have learned to justify reading it. I've also ripped through Timothy J. Koegel's The Exceptional Presenter… so I'm geared to improve my videos (we'll see if they actually get better!)
|The Exceptional Presenter: A Proven Formula to Open Up and Own the Room
by Timothy J. Koegel
|Camtasia Studio 5: The Definitive Guide (Wordware Applications Library)
by Daniel Park
I have two more books on this theme on the way, and I'm quite eager to see what they have to offer:
|Presentation Zen: Simple Ideas on Presentation Design and Delivery (Voices That Matter)
by Garr Reynolds
|Beyond Bullet Points: Using Microsoft® Office PowerPoint® 2007 to Create Presentations That Inform, Motivate, and Inspire
by Cliff Atkinson
Who knows what nuggets these might yield?
Note, I've tagged these "Videos and Presentations" on my Library site and will tag some more as soon as I wake up. If it turns out anyone has an interest, I'll create more tags for other relevant topics. For now, the books I think are among the best are tagged "required"
