Provide for ES values of up 2.4 for alt pro work.
My current cyanotype sensitizer has an ES of 1.9
The base ES value that shows in ExpoDev is actually set by the film test analysis in Plotter. In Plotter you can set ES values up to 2.0. In order for them to show in ExpoDev, you then need to export that film test and load it into ExpoDev. Ideally you would have separate film profiles in ExpoDev for the different ranges of papers you wish to print on.
