Up-thread it has been stated that E6 film is a little easier to manufacture than C41....but while we might be happy to see more E6 film of good quality, that's not what the audience for this social media campaign seem to want....nor are Kodak or Fuji having difficulty supplying their E6 films. There *is* a gap for a faster E6 film for sure, but it's one of those "niche within a niche within a niche" products. I can't see it paying off for Harman if they've invested any kind of significant sum on this. The market, and money, is in amatuer 200 or 400ISO C41 films in 35mm....and if they achieve a good reputation and good sales in that they might then branch out into 120 and other speeds.
My favoured local lab near home doesn't do E6 but can send off to a small lab that does....or I can send there directly. I do have a reasonable choice of E6 labs but that requires mailing my films at considerable cost (Royal Mail price hikes in recent years really do add up) compared to walking into the shop with the mini-lab that does C41. Notably, what was "Snappy Snaps" near my workplace has now reopened after a four year closure as an independent photo lab complete with mini-lab and both Kodak & Ilford film on sale. I might pop in soon to get to know them and see what services they offer.
Bellamy saying "it's not what you think" is intriguing though. As for his hatred of Fuji, their lack of transparency regarding their future intentions of 35mm and 120 film production seems to really anger some people. There's at least one UK film retailer who regularly bashes Fuji for this too, to the point that I believe they actually hate Fuji. But they're just being Japanese....and Japanese business culture really isn't anything like as open as American, British or European - and even we have our trade secrets. I'd never expect Fuji to actually be forthcoming about their future intentions.
