I am trying to understand the logic behind what is considered or not LF in this forum, according to the FAQ.

If I read it correctly:
- Direct positives, regardless the size, are not considered LF because it is paper, not film. Unknown to AA, most of his work with Polaroid is not considered LF here.
- Scanning backs listed as 4x5 are considered LF, even if the image captured size can be as small as 2.8x3.8".
- The film in a 665 (3.25x4.25") is not considered LF because is smaller than 3.5x4.7" (9x12cm)

I hope the discussion will help to improve our understanding of what we should or not consider LF.
