I can forgive you the cynicism born out of ignorance, but not if it is born out of an hidden agenda or pure malice.But is a new emulsion? I doubt a little.
ISO 320 ????
If a new created retro emulsion would
be have ISO rates of 64/19`DIN I could imagine "Smart/Clever Marketing "
It's different from Fomapan 400 - the datasheets show this quite clearly.
I recall some testing found it was about a 200 speed film in the 'special' developer at a normal (mid 0.5s) contrast index. 2/3 under box in MQ developers is generally not surprising for Foma's films.
Ian Grant (I think) commented that a lot of manufacturers used to make 'soft' gradation films many decades ago. A 100-160 speed (pre-1960 ASA change) film of that type would therefore have not be totally unsurprising in their range in the 1940s/50s (Anyone got a 1950s Foma or Neobrom catalogue?). Anyway, I'd not be surprised if Foma had the formula for one, updated it etc, put it into production. That would go some way to explaining the fairly intense grain some have commented on. Foma themselves, it should be noted, recommend the sheet film 320 for contact printing on to Fomatone etc.
The preference for the 'special' developer also adds credence to a much older film design - it is quite an aggressive developer (relative of DK-60a?) to get the times down into reasonable ranges for useful contrast ranges.
I keep meaning to give some of the sheet film a go, but have been a bit too busy to get on with it & see how it behaves under different lighting etc.

"Retro" refers to a style of film, not a copy of an old style film. I would expect the style to reflect the fairly soft, wide latitude films that were available in the 50s and 60s, but not all retro films are like this. These old films could be developed to fairly high contrast in the aggressive developers of the time; Ansco recommended gammas of 0.7 to 0.9 and Kodak recommended 0.6 to 0.8 when developed in D-76 (undiluted), DK-50 and similar soups. In general, you should consider the new "retro" films just to be films, with their own peculiarities, that may or may not reflect an older style. Try them and get used to their characteristics, just like any other film. There are no promises, but you may like some of them.
As for speeds, the old ASA speed (ca. 1950) equivalent to ISO 320 would be in the 125 to 160 range. They measured speed differently then, so an exact comparison is not possible. There were a number of films in this speed range: Ansco Superpan Press and SSS Pan; Defender Arrow Press; Kodak Supepanchro Press Type B, Superpanchro Press Sports Type, and TriX Panchromatic; and others from European manufacturers. Most of these were pretty grainy and not very sharp, but they were useful as sheet films for press work. I would expect any modern "retro" film to have much better photographic characteristics, which may involve some compromises with latitude and contrast.
So, trendland, what have you decided to do in terms of trying or not trying Retro 320? A one sentence answer will be fine

It is the second time in 24 hours that you throw doubts at what manufacturers tell you.
Here is a link to a thread I wrote about this very different film.
All you had to do was to search this forum, instead of throwing mud to one film manufacturer that still does R&D:
(there was a url link here which no longer exists)
But you shuld know the risk with a houseI have bought houses with less research.
Why do you fear this may be in short supply due to "unspecific ancestry"?
Foma have told us what it is. It seems to be self sustaining in that they are selling enough to continue production.
What's the problem?
Sorry - may be you just missunderstoodTrendland:
Try it. Stop wasting your time with logorrheic & probably incorrect hypotheses. Write to Foma & ask them about the film if your existential crisis is that great. However, you appear to have a desperate urge to create pointless uncertainty & doubt around a number of well documented products in a way that some might increasingly construe as concern trolling. Asking ceaseless questions without reading the answers & experiencing the materials for yourself is not a useful learning experience.
I think most reasonable people will try a new film, see if they like it, buy some, use it, & if it is discontinued through a lack of demand possibly be a bit annoyed - but being forced to change your materials can be a good thing.
Part 2 of two parts:
But if thinking in this way would imply that the manufacturer - just in this theoretical example - is unable to reproduce the emulsion from his defective produktion run again.
So his new film should be from the market after few month - and every new
"Fan" of this film wouldn't be glad aboud.
But is it totally unrealistic at these days?
No - because of the very smal demand of
this marked we have today.
And with a very special emulsion like
Retro320 soft from Foma. ........... ...?
Thinking on Agfa - how many years after
Agfa was from the market - their latest pruduced bw films were sold?
WITH different names and to so many years.
Because of the smal market.
Looking to my roll 135 I noticed it is labled with paper!
That is nothing what tells us anything to
production at Foma Film but it strongly indicates a small production line - may
be because of a rare Film (Retro).
Coming back to your extraordinary experience with this special emulsion
Lachlan - I absolute understand you
corect in the way that it is imposible to say this Foma Film is anything else
than a totaly new produced film.
Because of the very special characteristic of this emulsion witch is first diferent than any other Foma Film
(sorry for saying this - but I have not any
experience with Foma at this time)
Secondly it is a character styled emulsion in the way of what is indeed
the experience of Ian Grand - made with
some emulsions from that time far behind. (pre 60th).
Do I understand this concerns correct from your statement ?
with regards
You open a thread with a question, yet you later come to your own conclusions and answer the question yourself.
What you want is a blog. This is not a blog, this is a forum. Create your blog and post there about the evil Foma factory. And about how films should always be ISO multiples of 100 (100,200,400...), never 64 or 320.
