Rights and use
You may teach with everything here. The formal terms are being finalised, and this page will carry them in full once they are.
Use the lessons in your classroom. Print the student handout, project the photographs, adapt the sequence to the time you have. That permission is not in question and never has been.
All photography is © Greg Smith. The exact licence for the lesson materials, and the scope of the grant covering the photographs, are being settled now — publishing terms before they are agreed would be worse than publishing none. If you want to do something this page does not yet cover, ask, and the answer is usually yes.
