Re: Back to the black spot issue

I do not really beleive in problems with manufacturing: within the same 
package of IR-film (Kodak 4x5), I hade some with and others without. There 
was a clear realtion between the processing and the occurence of the spots 
(either the neg's processed at the same time do have the spots or don't), 
although I proces my neg's always exactly the same...
