I have used many varying formats in the past. Currently I'm shooting with a Nikon Z9 with various Z lenes. However, I like mixing the new and the old technologies and have had success with 30 year old Nikkor lenses on the Z9.
The Arizona images were photographed using a medium format digital camera and the Potomac images were photographed with a Canon 5D. All of the landscape images were photographed with a Hasselblad Superwide film camera. The film was then scanned and digitized.
