No I think you misunderstand me. From a chemical point of view. The photographic process can be a tricky subject. Please remember there are people who have Doctorate of Chemistry where their Thesis is the complexes of water! We can determine crudely what can ocure during the photographic process. BUT how do the photons excite, how much energy is released, why use certain salts ect. I'm speaking as a chemist not as a joe normal. ( In the words of a close friend chemistry is about minutia! ) I'll try to explain myself better. Kodak's understanding of the chemical process can be similar to a physicians understanding of cancer. Sure thay can know a lot. They may have even developed processes which can detect, reduce, and cure cancer BUT they REALLY don't KNOW EXACTLY all there is to know about cancer. Bsteph
