I've just to use CHS 8x20 and 8x10 films and at the first used I didn't have pinholes or other problems. I use to pre-soak the film in water and a little hardener and after I use a pyro ABC developer, stop bath very light and a normal fix. The negatives I've taken so far are very good, no problems, and for me Adox CHS 100 is been a discover, I hope to use more of this film in future. Thanks to Adox and to Mirko for every news and for their Job.
