After you take the photo, what are you supposed to do: print it out? Load it onto the class computer to share? Distribute it via email?

Does he assume that everyone has a digital camera? *Does* everyone have a digital camera?

Most importantly, can you get your fees back if end up dropping the class?

FYI, the fact that the class meets at a time that doesn't work for you, doesn't mean he didn't get your email. That time may have been the least inconvenient for the group as a whole.

I hope this, or something like it, works out for you.
