I realise product comparison posts have caused problems in the past so I hope this thread is reasonable. In his toning book, Tim Rudman gives a particular recommendation for the Maco selenium toner. I have been using the Fotospeed product. Has anyone made a comparison of selenium toners, or noticed any significant differences between the various brands? I'm aware of these brands on the UK market: - Kodak KRST - Fotospeed SLT20 - Maco selenium toner (apparently contains 3% sodium selenite) - ILFORD Harman selenium toner - Moersch MT1 (via Germany) Tom.
