Here is an edited recording of the class 3 session. It runs 53 minutes.
Here is a pdf of the slides.
In the first part of the class we talk about how to pick up visual clues in the images. You can see larger still images here.
In the second part of the class we talk about dialing in the prompt to make it accessible to a group of people. We then go through a quick exercise on the ImageCenter to show how that works.
