    LF Clarification

    A number of members requested clarification of how the forum defines "LF" - essentially, what image formats are allowed to be posted, and where, on the forum. After considerable discussion among the moderators and the forum owner, we have changed the FAQ as follows:

    A. What is the Large Format Photography Forum all about? - The purpose of the forum is to provide a place for discussion of topics of particular interest to large format photographers. We especially encourage questions which will help build a repository of knowledge about the tools and techniques of large format photography. Commonly accepted definitions base large format photography on 4"x5" and larger sheet film, regardless of the style of camera being used. This is the definition we will use. We would also consider a digital back with a nominal sensor size of 4"x5" or larger to be LF, as well, regardless of technology.

    Over time, these definitions and boundaries have changed. The current definition was established in September, 2014. Prior threads that no longer fit this definition will be moved to the appropriate forum only if new postings are made within them.

    B. How is the LF Forum organized?
    LF-related Forums
    . . .
    Image Sharing (LF) & Discussion - Post your own large-format images (based on 4"x5" or larger format) for sharing and discussion. Critiques should only be offered if requested by the original poster.

    Image Sharing (Everything Else) & Discussion - Post your own images of other formats and types here for sharing and discussion. All rollfilm formats (rolls less than 4" wide) and medium-format digital formats belong here, regardless of camera used. Critiques should only be offered if requested by the original poster.


    You will note that this adds a sub-forum in the LF-related section for posting and discussion of images that are not "LF" as we define it. This should resolve the confusion created by our previous policy of "grandfathering" certain formats that weren't really "LF" but shared the LF working style based on the camera being used.

    Interesting solution. Having been in on these discussions previously I know how difficult they can be to arrive at a consensus. It sticks to a more traditional definition of what LF is while adding room for everything else. It should work. Of course like anything, not everyone will be happy. Thanks for your efforts.
    Thanks,

    So, does that mean 6x12 and 6x17 are "accepted" in the LF category, being ~4.5 / ~6.5 inches wide? Or are you talking about the "width" of the roll of film (2 1/4), meaning that all roll films shot on LF cameras w/ rollfilm back are now not allowed?

    Re: LF Clarification

    Images made on film whose smaller dimension is less than 4 inches, are no longer by our definition Large Format, even if they are very long in their other dimension.

    For example, a horizontal landscape negative or transparency that is 1 inch high and 10 inches wide, is not Large Format according to our definition, even though it might have been made on an 8x10 view camera.

    By contrast, a horizontal landscape negative or transparency that is 4 inches high and 10 inches wide, is Large Format according to our definition.

    Non Large Format photos and related discussion are still welcome, but not in the Large Format forums. They fall into the category of "everything else".

    There's discrimination there against 9x12cm which is the Continental European equivalent of 5"x4", modern DDS for both sizes share the same outside dimensions.

    After all identical Linhof models sold in Germany and and also Zeiss, Schneider and Rodenstcock lenses were marketed as for 9x12 while in the US for 5x4.

    Huh. Can't say I agree with that at all. I didn't think that was part of the discussion at all, but whatever...

    I disagree.

    Why not make the definition so that it includes cameras that have camera movements? This would then expand to 6x9 view cameras. Basically this would also exclude large roll formats like 612 and 617 unless they were taken on a view camera with movements.
    Then images shot with a 45 view camera with a 612 or a 617 roll back would qualify.

    I agree about cropping being commonplace and normal practice, but it's a matter of degree.

    Jonathan described a sheet of 4x5 film cropped-down to something "much less". The term "much less" is open to interpretation.

    If our definition of Large Format excludes a 6x7 image made with a roll-film back, but allows a 4x5 sheet-film image cropped to 6x7, is that fair or consistent ?

    One solution would be to extend the definition to 4x5 inches cropped by no more than x%. Is there a reasonable value for x ?
