The film versus digital and the "real camera" versus smartphone debate reminds me of the "proof of work" concept in blockchain systems such as Bitcoin. In blockchains, a party establishes the truth of a statement by proving they worked hard to create that statement. Talk is cheap, but proof of work shows you put your money and time where your mouth was.
These days, anyone with a smartphone (and almost everyone has a smartphone), can make automagically-decent spray-and-pray images. There's almost zero work required to get a decently exposed smartphone image. Smartphone images are cheap!
By contrast, a person with "real camera," especially a person with a "real nice camera" (e.g., flagship) or a "real big camera" (e.g., medium format camera) has proved they invested a lot of money to get the camera and a lot of work to carry it around.
However, modern digital cameras, even the big, expensive ones, are still too easy. Put them in P-mode (aka "pro-mode"
), spray and pray, and some good shots are inevitable.
In the "proof of work" spectrum, the next step up is film, especially with a vintage camera (the larger the better). Good exposures aren't guaranteed, spray-and-pray isn't really possible, and the inability to chimp-and-reshoot means the photographer has to know what they are doing. Film images take work to both learn and execute a decent photograph.
Finally, the pinnacle of "proof of work" are techniques like wet-plate collodion that require significantly more work to make every single image.
Thus, whether fair or not, if one sees two images and knows that one was shot on a smartphone and the other was shot with 4x5 film camera, the smartphone image will be valued less than the film image even if they are similar in composition and subject matter (e.g., some street scene).
Camera makers know this and create cameras and lenses that enable photographers to prove their images show proof of work.
