Dear Philippe,

I cannot till you return the negatives for examination by us: I have checked for any outstanding or known QC's ( Quality complaints ) regarding 'spots' : We have none whatsoever, on any film products. We would need to examine the negs ( usually done with our electron microscope ) and we will give you our analysis, we then check control samples and unexposed samples from the same parent roll your film ( we hold unexposed slittings for 6 years ) was finished from to see if we can replicate or find a similar issue to one you describe.

Kind Regards
