Hi Mirko: Is the Adox CHS 100 and the Efke 100 film made at the same plant using the same machines? Are the products exactly the same? Again-is there any discernible difference of any kind between the two films, i.e., does one have "built in" hardeners? I ask because there is apparently continuing confusion about the series of emulsions that are the same as the older Adox emulsions, and I would appreciate your "setting the record straight" once and for all. Thanks.
