Adox Scala iso 50

[Steve@f8]

Although designed to be processed as a reversal film, I’m wondering what might be expected if it’s developed as a negative film, for instance using HC110 or Rodinal.
Few labs if any offer B&W reversal processing in the U.K., presumably due to throughput making it economically unsound.
Another aspect of the film I’m interested in is the clear base (apparently). Does that affect anti-halation?

(PS I did a search before starting the topic, so I don’t think I’m duplicating a previous threads - at least I think so.)

If you read the Fotoimpex/Adox sites carefully, you will realize enough hints on this film

-) being designed as negative film

-) not being made by Adox, but just converted by them to 35mm

-) and then with the ending of their Scala 160 in addition relabelled as reversal film

Fotoimpex offer this film in two different versions as negative film, one of them worked on by them. They furthermore offer a developer made by another firm rebranded by them as dedicated for negative processing of this film in the latter version.

Thus you got choices enough. Most work would be in reading their sites carefully. They argue that they do this different labelling to just not confuse users with choices of different processing of same film.
So to be able to pick a slide film off the shelves and sending it in to the very few dedicated labs without hassle.

Strictly speaking all classic films we use have a clear base, as otherwise, neither contacting nor classic enlarging would be possible.
What you mean is being undyed.
In this very case dying gives no benefit for its intended use.

Due to having an AH layer of the Agfa-type, thus between emulsion and base, there should not be halation forming, nor has such has been reported.

Another issue is the lateral light transmission of undyed PET base. This has been tackled at the many advices no to handle cassettes with such films in strong light, let alone store them in strong light.

The Adox site says in can be processed as a negative using HR 50 times.
Has anyone tried this, and if so can someone post an image or two to give an indication.

IIRC @relistan posted some examples of Adox HR-50 developed in his experimental two bath developer. On Facebook I saw some nice pics by Rudiger Hartung who used Rodinal for this film.

Have been off the site for awhile due to being overly busy. But yes! It works well in two batch developers or anything that does some compensation.
