    I just measured the actual image area of a recent 4x5 negative and it comes out to 3 11/16" x 4 11/16". So are THOSE the minimum dimensions we should be talking about? If we require an absolute of 4" as the minimum "short side" dimension I'm afraid we'll become a forum for 5x7 and above.

    Dang. I guess I'll have to resign from this fine forum. I don't have a 5x7 camera.

    Brian, I think you mean you don't have a 4 11/16" x 6 11/16" camera.

    Perhaps is should be stated as "film formats 4x5 and larger".......which would include the digital backs.

    Sounds good to me. Not what I would have expected (I felt that the definition was more camera-related than film-size related), but I can easily work with this definition.

    Good to hear that cutting a piece of 8x10 film in half (two 4x10's) makes the cut! I am a little concerned that those who are cutting 4x5 or 5x7 film in half (in camera -- using a modified darkslide or internal dividers) to make panoramic images, or significally cropping a 4x5 (or larger neg) to less than 4" on a minimum side, would no longer be classified as using LF.

    I would consider both of these LF...but more than willing to play by the new rules. (Both are on 4x5 film)

    Well, lets take roll film cameras a bit farther.

    This is the Linhof Aero Technika 45El shooting 5" (120mm) roll film on modified NATO spools. There is one shot of the camera and another of the astronaut Pinky Nelson using it on a Space Shuttle Mission. It was placed on the Shuttle program by the US Navy but imagery was done by NASA and assignments would come from NASA as well as other agencies.

    Here is another Linhof 5" roll film camera, the Linhof Metrika. It is the camera used to take the measurements of Otzi, the Ice Man that is 5200 years old that was found in the Alps in 1991. HABS also used two of them for documenting various places or buildings or rooms for the National Park Service. It has a Reseau plate in front of the film and made extremely precise non surface contact measurements when used with a photogrammetry program.

    So, would images on 5" roll film qualify? If so I can post one of the Otzi pictures if you like.

    Yes, they qualify as Large Format according to our definition...

    ... as do 4x5 pinhole cameras, Polaroids conversions and home-made fixed-lens designs we see from time to time.

    4x5 is where we have drawn the line, Jonathan's hair-splitting exactitude notwithstanding

    Other formats are also welcome, just not in the Large Format areas.

    that is why I feel that adjustable cameras are the definition of a view camera since all of you are using those adjustments to make images as opposed to others who just use straight images from cameras that do not have movements, regrdless of the size of the film. But then, of course, a T/S lens or a shift lens on a mirrorless digital camera could also qualify.

    But, representing a camera manufacturer, they do consider a 6x9cm view camera large format. And a camera like a TK23S can do more in the way of movements and corrections then many of the large 45 and larger cameras can do that are used here.

    But Bob they are not defining what a view camera is but what Large Format is.
    Thanks,
