I will be attempting to photograph the Zion Subway with a medium format camera - facing down river. I will need to rent an UWA for this one.
To comfortably get the entire left "rib" (the curve part) and the entire right pool of the Subway, what focal length should I have prepared (in 35mm terms)? I have attached an approximate photo of what I'm referring to.
*Photo was taken from the Zion National Park site - https://www.nps.gov …anyourvisit/thesubway.htm
Thank you in advance for your helpful comments and suggestions.
