It's my understanding that the 'bleed through' phenomena came to attention of the makers of Shanghai GP3. As you can imagine, many people complained about the film and their response was that the 'bleed through' was a result of improper film storage, with high temperatures and humidity to blame. If that is the case, it's plausible that many batches held by retailers/wholesalers were not properly stored as temperatures and humidy can be quite high in parts of China/Hong Kong. This can account for the defects that many experienced when using this film.Is the what you have still in the red wrapper or has it been changed to the silver wrapper? I'm worried about the keeping properties due to the number bleed-through. My fresh stuff doesn't have it, but I'm wondering if it will creep in during long term storage? Time will tell I guess. JW
My advice is to freeze or refrigerate the film as a cool environment will mitigate these conditions. Regardless, it's not much comfort to those already burned, especially considering the manufacturer could have revamped their product to avoid being susceptible to such a common environmental condition. Nonetheless, there is no guarantee that this will address the problem and I have not directly read anything from the manufacturer to corraborate what has been relayed to me.
Despite the potential for problem, based on the user experiences in the past (prior to the 'bleed' problem) and my own personal use, Shanghai GP3 is quite a decent film. If you don't mind the risk, it is a worthy addition to your shooting arsenal.
