As for photos in my gallery, they are all positives (i.e.. slides), not prints. Scala was designed to be reversed, that is processed as a positive rather than a negative so I assumed that's what you wanted to use it for?? (Why use old Scala to be processed as negative then printed from if you can use many other, better and fresher films?)
Dr5 is a lab which chemically reverses b+w 'negative' film into b+w positives, i.e.. slides.
Hope this makes things clearer. (Although I often confuse myself )
