Shana: The curator was given access to the images after hours (when the museum was closed). I don't know what equipment was used. Additional images were solicited from the public, and interested donors were asked to contact the curator at the museum. The curator met with image donors at the museum, during regular work hours. The book's acknowledgements thank the museum and state that "unless otherwise credited the images in this book are from the museum's collection." When asked about paying fees, the curator responded "If I have to pay for the images, I am not doing the book." This was my red-flag moment. (I am not the curator).
