Regarding original 35mm negatives. This film format does deteriorate over the years, but the negatives will make nice scans and can be tidied up with software like Photoshop. Many negatives will be, forty or fifty years old and will therefore have some imperfections, they always do. If your unhappy with this statement then please don't buy!
