In reply to Giving talk about type:
I would distinguish between typography as done by graphic designers and type design, and focus on typography.
If you are speaking with visual aids (Powerpoint?), you can demonstrate how a typographer can change the appearance of a page by altering the basic typographic parameters: typeface, size, leading, and paragraph style.
That way, your expertise in speaking and presenting will be demonstrated in the way that you strike a balance between what you say about the images, and the text that you have written for the descriptive captions in the images.
It does seem to me that you should be using images in your talk, as the subject is visual. However, if it’s just talking, you could discuss a non-visual aspect of contemporary typography, such as the change that was brought about by digitization; the “how it’s done” in this case would be the emergence of the independent foundry and how we go about our business: technology, design process, marketing, distribution, the difference between royalties from licensed products (passive income) and commissioned work for fee.
