@Ian: May I know the details of quick testing? I have a film(Fomapan 400 bulk roll) + Incident/Reflective meter + Developer(Rodinal 1+50 and Tanol from Moersch) + Adox vario classic paper.
I do not have any device to measure the densities or have any interest to send it to prof., testing services, if available.
How do I establish the personal E.I.?
