The Ilford Ortho Plus spec sheet gives developer information as well as how to adjust for reciprocity for exposures longer than 1 second. That's important, because this film would be great for photographing waterfalls. Also, note that if you use it under tungsten lighting, the ISO rating is 40.
Anyhow, I look forward to testing a roll or two and see how it performs.
