I am watching unfold a handful of discussions online, as usual, and recently I've been seeing a particular breed of photographer crop up. These fellows are the guys who are pretty sure that a large format film camera is what they needed all along to make their pictures awesome. They're wrong, of course.
What's interesting to me is that I remember being that guy. I still own a large format camera, and keep meaning to get it out. But somehow it never happens.
The discussions have the usual back and forths about the superiority of film (no! the resolutions and ranges of dynamic stops and and) but what it always seems to boil down to is some vague notion of feel. "There's just something about..." is a phrase oft repeated in several variations.
Here's the thing. Outside of certain obvious clues which are easily managed if you know what you're doing, you cannot tell. It is not even hard to take a digital photo and edit it into shape to appear like film. Large format film has no special creamy tonality, it just has very fine grain and, potentially, some interesting properties in the field of focus. Those giant 8x10 negatives with all their incredible detail and beautiful color rendition and choirs of angels? You can do that all with a good modern digital camera, except for the angels. Angels are notorious for hating on the digital.
All the amazing properties of film vanish when you start blinding the tests, as long as you avoid the obvious giveaways (which are either errors, or not properties of film vs. digital).
More to the point, nobody cares what medium you used. What they care about is content, invariably. Over "basically pretty sharp" the only people who care how sharp your picture is are other photographers, and not the interesting ones. Beyond "skin looks like skin, sky looks like sky" ditto for color rendition. As for "tonality" I don't even know what that means, and nobody else does either. It appears to be a bullshit term used by photographers to mean "special properties that only very sensitive people like me can see and I can't explain it to you because you are a philistine but it is super important. trust me.'
I've said it before and will, no doubt, repeat myself. The reasons for using film, be it large format or otherwise, have zero to do with the technical properties of the medium. The reasons are, nonetheless, excellent. If you prefer to use film, then you should definitely use it. It does not change the pictures, but it changes you, and of the two, you are the more important one.
