Re photography, I was thinking first of metol (1891) which (apart from its early confused history) up until about the 1960s was thought to contain paraphenylenediamene impurities sufficient to the be the cause of 'metol poisoning', the contact allergy that was noted in many users. It was thought by Grant Haist that modern metol does not contain this impurity and is not particularly allergenic. But that could mean that for the first 70 years of its use, there would be a solvent or fine grain effect from the ppd which would not exist in metol made later. As with so much in photographic engineering, there is no published proof. Re audio compression, I have often wondered about that. I would say it is only now that I am finally learning to use dynamics effectively in my own playing (classical piano). But I've always tended to work with German pianos made from 1890 to 1920, which tend to have the largest dynamic range. Also there is the fact that truly soft playing is hard to record, and often comes out louder than you are hearing live. But take everything together, and I believe you are right. One thing that makes it hard to discuss is the stark difference between analogue headroom (gentle and long) and digital headroom (sharp and short). My eyes were opened by a Horszowski recording where the phrases mostly follow a suggestion I heard Casals make, that, in most cases, when the phrase goes up, there should be a crescendo and when it goes down there should be a diminuendo.

Fascinated by this post. I have used some of Fraterworks' raw materials and love them. And would gladly spend all I had on ordering more. It seems that there is the same issue in perfumery that there is to some extent in photographic chemistry, that improved methods of synthesis can sometimes lead to unwelcome results. And with restored audio and films, they are often so clean that the magic is simply not there. The modern version of 'Bird of Paradise' loses the poetic luminosity of the original film. The reconstructed soundtrack for 'City Lights' is missing some essential something, even if that something is just noise that, paradoxically, may help us reach towards the essence? Would love to hear your opinions of their raw materials and their bases. Some of the bases can be hard to find on their site.
