I recently developed a 35mm HP5 film, and found that messuring base + fog with my Heiland Splitgrade, this was 0,33. The develope before date is 2009. Admittingly this film has been through aerport control twice. Is this level of base + fog to high? I developed in Ilfotec HC 31+1 for 7 minutes. What level of base + fog should Ilford films give if fresh out of the factory? Should a question like this be asked on the Ilford website?
