Just one general statement concerning what we are seeing - or are not seeing - out in the streets:
As someone who is doing very successful market research for a very long time, I can ensure that these anecdotical observations (both positve and negative ones) are often interesting and entertaining, but they are completely irrelevant for a proper market assessment.
Just three examples to make it more clear:
1) Several million digital ILC (interchangeable lens cameras) are sold every year. Demand is significantly declining, but nevertheless still millions of units every year. I know almost all the different types and different models. How many of these different models have I seen in the last years out in the street, or on photographer meetings, or photo fairs?
Maybe 5 - 10% of them, not more.
I know that manufacturer A is selling hundreds of thousands of units of this certain camera model XY p.a.. But I have not seen any of these units out in the streets. Based on my personal observation: Would I now make the conclusion that this model is not sold well, or sold at all? Of course not!! Because if I talk to camera distributors they show me the numbers and I see that quite a lot of this model is sold, the demand is there.
2) Film photographers here locally out in the streets:
Do I see some? Yes, but seldom.
But when I go to my local lab or camera store, I see them in big numbers. So I know: Yes, film is regularly used in my town. Despite the observation that I seldom see some "out in the streets".
By the way, and that is often forgotten in these discussions: What kind of photography can you as an enthusiast photographer do "out in the streets": Mainly architecture and artistic street photography. How many of us are into that? Certainly not the majority.
So the observation that we don't see so many film or generally enthusiast photograpers "out in the streets" may also be caused by the simple fact that our streets are not our main shootings locations, or our preferred genres as (film) photographers.
Here in my town I generally don't see so much enthusiast photographers "out in the streets".
3) Instax:
How often have I seen an instax camera used "out in the streets"? Only one time in the last two years: Some young girls used one at the neighbour table in a cafe.
But
- I know that friends of mine are using it
- my niece has started using one
- a friend of mine asked me just today which instax camera I could recommend for his 17 year old daugther, she wants one
- my local camera shop is selling 2.000 instax film packs every months
- Fujifilm has sold 10 million instax cameras in their last fiscal year
- my local drugstore chain shop offers it and the shelves are always getting empty and being refilled
- I am using it myself for years

.
So from the "have I seen it out in the streets" point of view you could come to the conclusion very few people are using it. But if you do proper market research and use the really relevant sources you immediately see that just the opposite is true: it's a booming product (Fujifilm itself assesses the market volume globally to be 40 million instax users).
The "can I see the product out in the streets" assessment is not able at all to give a really valid and proven market assessment. Not in photography (neither film nor digital), and not in most other product / market areas.
For film photography the data from the
- film manufacturers
- paper manufacturers
- film distributors
- photo chemistry manufacturers
are relevant for a valid film photography market assessment.
And this data is very clearly indicating a film photography revival, which has gained momentum in the last 18 months.
