Hi guys
Thanks for the replies - they have given me some useful ideas.
I have had a look through my Darkroom Cookbook where there is a short section on Negative Intensification.
I don't fancy giving Chromium Intensifier a go as one of the main ingredients is hydrochloric acid and the other potassium dichromate - both of which are hazardous.
However, it says Ansel Adams used Selenium Toner to intensify some of his negatives at a 1+2 solution for 5 minutes - which sounds pretty easy - so I'll give it a go let you know.
I also still fancy having a go with Beers Two Solution variable contrast developer and mixing up the developer to a high contrast solution.
The Darkroom Cookbook has the recipe and Firstcall have all the chemicals available.
I remember the keeping properties of the made up solutions as being very poor, so I'll need to get myself set and ready to go, if I want to try it out.
Thanks for your help.
Martin
