I've recently seen, for the second time in my experience, a posterization effect on slow film -- this time Adox CMS 20, formerly on Kodak Tech Pan, and in both instances I used a similar developer. The developer in both cases was a phenidone developer. Anyone have any idea of the cause of the effect? I'll try to get an example to post.
