Konical - Gosh, I wish I'd gotten this before I left for town! But for #10, this will be great. I had TMax film, but was thinking it had less latitude so didn't take it. rats. And the black card idea is a great one I never came close to thinking of on my own. I'll try that next time for sure.

#9 makes me think I may get nothing because I didn't have any exposures even close to a minute. You're right - further trips will be needed, and we're looking forward to doing it again. Thank you!

Phaedrus, I'm not at all sure how the -1, -2 applies to my camera. I guess I don't understand, but it's ok. Thank you for replying. I'll look into that.

Thank you both.
