Scala as positive?

[pierods]

I have an exposed roll of Scala that I don't care to process as a positive.

What happens if I process it as a negative? Is it possible? Should I process it as a regular 200 iso negative, say foma 200?

snip test it

snip off the first 4" or so - and then process the snipped part with another roll of film to simulate the effect of the developer working on a whole roll of scala that you want to develop. This should guide you as to any fine tuning of developer time for the rest of the roll to be processed at.

Works very nicely (for me) with Rodinal!

That gives ballpark times for many developers.

many thanks to all!

I noticed in the old Agfa pdf files that the spectral sensitivity graph for Scala was exactly the same as the one for APX100. I wondered if they are the same film, but perhaps with different base (the Scala being more transparent for projection perhaps). Some one gave me a few rolls of Scala in 120 that I've not used.

Piero, could you let us know how yours goes?

..as mentioned, rodenal or d23

I will.

I have tried it at ISO 160 in Rodinal Special, but it came out too thin. For me it is a true 100 ISO film. Try it in Rodinal, the tonality is truly exceptional.

Here it goes:

scala 200, id-11, stock, temp-compensated for 23.5 C -> 6:45 min, ilford agitation.

very clear and thin base, reminds me of rollei ortho 25.
