What is your definition of "commercial use"?
I would like to take photos of the exhibits and/or plants at the show that would be potentially used for outreach and/or promotional material at the 501(c)3 nonprofit I work for. Is this allowed?
Yes, you would be able to take photos for your social media and charity (non-profit) purposes. "Commercial Use" would apply to professional photographers who intend to sell their products for commercial purposes. You would not be in that category. But thanks for checking in, and enjoy the Show!
