I see what you are saying. If I understand correctly, the name Kodak no longer means retail, as in home users? Just wholesale for giant users? At least that's what it sounds like to me, anyway. Yes, the Photrio crowd might be small, but they would be a good indicator as to what the "home photo enthusiast" elsewhere would want. Matt, your last sentence leads me to what my 2nd and 3rd sentence above are getting at. I guess us small photo-nuts are just plain too small for Kodak, but not too small for Adox, Bellini, Foma and that's OK by me.
No, not really.
In fact, it is almost the reverse.
Historically, when it came to chemicals, Kodak meant high volume, commercial users.
Plus they did some small packaging for the home user, because they were already servicing that market with film.
Kodak did their own distribution, so they could easily add small packages of darkroom chemicals to the regular deliveries of film that went out to the type of dealers who serviced that sort of customer - the "camera store" dealers. Most film, of course, was delivered to grocery stores, drugstores, stores serving tourists, etc. The business focused on home users was simply an offshoot of other business, that could be serviced profitably because of that other business.
That entire distribution network is gone. That world has almost gone. The infrastructure that supported it was hugely expensive, and when the world switched away from film, the costs related to that infrastructure bankrupted Eastman Kodak.
The photo chemical business that Photo Systems recently set up again has no such low cost and efficient retail distribution system to trade into - they are having to get Cinestill to supply as much of that as they can. I expect Photo Systems has made their package size decisions based on the need to minimize how many SKU's they support, while having product that is packaged in sizes that might be useful for both individual small users, as well as larger, commercial users, to the extent that they are still around.
Adox, Bellini, Foma, Arista, Photographers Formulary and the like are able to service their own niche businesses, and they have chosen to do that. Geographic and other realities mean that they are able to trade profitably in some markets with small packages. But they probably can't compete against some other choices offered by Photo Systems' Kodak branded products, at least in some markets.
Personally, I find a 5 litre package of X-Tol to be eminently practical, and I'm a small volume user.
By the way, I don't think Photrio does provide a good market indicator, because of the concentration of experienced people here. I think the profitable market that needs to be served is a larger one, with a higher percentage of less experienced people - ones who don't rely on forums like this. And to a great extent, they buy based either on reputation - where the Kodak brand probably helps - and price - where the distribution realities make it difficult for Photo Systems to compete if they intend to sell small packages.
