There is a niche market, probably growing, for film photography of weddings. I read an article about this in the NY Times just a couple weeks ago
https://www.nytimes.com/2023/05/04/...edding-film-photography-has-a-resurgence.html - but you don't need an article to know this. Just go look at the websites of current film labs, and see what they are showing as examples of their work, for ex
https://thefindlab.com/ , or Richard Photo Lab or Indie film lab. There's wedding and portrait film photography all over it. Now, that's a generally different market from what the OP asked about for product / studio photography, and I'm sure wedding / portrait clients have a very different set of needs from art directors or other commercial photography clients, that may tend to support film as a viable niche.
