Adox and Efke are coated on the same machine.. Correct? I guess i must have been lucky. I use to shoot Efke until i noticed missing emulsion on 4x5 sheets and losing half of my first frame on 120. I starting shooting Adox after this not realizing that its the same film just sold under two different names.. I know this does not make sense but i have never had any issues shooting Adox 25.. I hope my luck doesn't run out because i have a freezer pack with Chs 25.. I should be put on that hoarder show because of that. I only use Rodinal 1+25 with a water stop bath with Chs 25..
