Item description:

Select the chapters where there are photos and follow a video guide to take pictures. Just redeem the photos already taken to unlock the respective trophies. Once done, select the final chapter for each episode and play it again. I think in 1 hour it sinks.
I think you can unlock platinum in 1 hourGood game to all!
Don't mind if you've already unlocked everything. To get the trophy to unlock all the 10 optional photos you just need to have taken the previous photos already. I tested everything on an empty account and it works. It seems as if the trophies unlocked are recognized and therefore it is as if the trophy of making all 10 chapters is a kind of platinum trophy that unlocks automatically.
I advise you to play a game if you have not finished this game yet because it is a masterpiece!
