Shanghai GP3 funkiness...

[Athiril]

When I soaked this is water for a minute (120 roll) before developing... the water came out a bright blue... like high school crystal growing copper sulfate experiments blue...

The film came out fine though...


What gives?

[Thomas Bertilsson]

No sweat. Don't presoak. If you can find one single instance where a manufacturer of photographic film recommends pre-soaking, I'd be very interested to see it.

[Athiril]

It was very startling to see :/

[Thomas Bertilsson]

Yeah, the colors can be pretty funky

Maco advises presoaking for the Rollei R3 in their datasheet.

Ever seen the 'juice' after pre soaking Tri-X 400/120?
BTW, I think I remember reading about pre soaking in 'The Negative' by A.A., I will check it...
I am pre soaking for about 35 years now and every time I did not, I had troubles, regardless the type of emulsion.

What's the problem? It's just the anti-halation coating.

Of course it is.

Thomas...Adox CHS 50.....presoaking recommended on the web site.....as well as only using water as stop. K

The benefit of presoaking in a water bath is more even development, as the "pores" of the gelatin emulsion are "opened up" before going into the developer.
