Two of these images were shot on P65 medium format backs. One on a Canon 5d2. Another on a Hasselblad 500 with Kodak Portra 160 film and the last a frame of Fuji 160 pro in a large format 4x5. I did a bit of minor color work to get them all in the same ballpark, and though the focal lengths and angles are not exact, AND the images I'm showing you are small, I still think it's an interesting discussion. More detailed post or posts coming soon, but I thought I'd put this up as a teaser. Let's see if you can guess which are which in the comments.
UPDATE: I've written more about this format comparison over here.
