Hi all,

I have always processed BW my self and I know nothing about labs. If a lab process 7222, could it process UN54 (orwo) similarly? Many thanks.

As far as I know, the processing for Orwo stock is the same as Kodak's. The PDF Data sheet on the film can be found here

The processing chemicals are the same but the time in developer to reach gamma 0.65 is longer on Orwo than on Kodak 5222. Every type of emulsion requires a different developer time and must be tested beforehand for best results.

At the aim gamma of 0.65 you will find a certain film speed to be used, don't trust the manufacturers speed information until you have tested.
