Complete ISO-Shutter Speed Work and Conduct Research on Daguerreotypes and Calotypes

You may take up to half the the class completing the review on ISO and shutter speed. Make sure your name is on your SD card when you give it to Mrs. Hogan.

For the rest of the class you will be continuing your research on the History of Photography. Today you will explore the Daguerreotype and Calotype.

On a google doc shared with me find the following:
What is a Daguerreotype? 
What does it look like? 
How does it differ from photographs of today? 
What length exposures were needed?
What were the styles of typical early daguerreotype portraits?
What were post-mortem photographs and why were they taken?
What is a Calotype? 
What does it look like? 
How is it similar to the process that we use today?
What is The Pencil of Nature? Who is the author/artist? 

Was the daguerreotype or the calotype preferred for most portrait photography uses in the early decades 

of photography? Why?
