5. A "talkie" picture is shown starting around time code 21:15. How does the audience in the film react to the "talkie"? What influence do audiences have on film and theatre performances? How do film and theatre actors influence audiences?

Photography has changed its subject matter quite a lot over the past few years. in the 1800's, it was considered normal for families to have  post mortem photos of their loved ones, and now that would be completely unacceptable. i think that photographers have always pushed boundaries and have been eager to capture everything, it is just society that changes their boundaries.

This would be tesserae.
