Cool. He’s a legendary photographer. I ran the numbers in this online tool and it checks out.
A 40mm medium format equivalent lens at f/64 will render everything from 0.37m onwards in focus. So if his ding dong was at 0.4m from the camera, it would be about 20-25cm in length, 9-10inches.
So it turns out he was using a high f-stop and has a cannon as epic as his landscapes.
A few discrepancies: Yes i know he used large format but do you know how difficult it is to set one up for a dick pic. The numbers are all over the place but it mostly lines up.
