On another thread, someone suggested developing ortho film in very-weak Dektol, like 1:15 for 90 seconds or so. Since my first shot at inter-positives on Ilford Ortho were too contrasty, this sounds good to me. The Ilford literature recommended only film developers and didn't mention Dektol. I'll give this a try next. Anyone have any experience with this? How about Rodinal 1:200 or something like that?
