So, i was thinking on doing a modern pulp scenario, that has to do with ghosts. One of the first ideas that i had, is that the players, will use some sort of weird science device, similar to the camera obscura from the game fatal frame, witch i'm still pretty new to it, just like the idea.

So, the players may be part of a paranormal organization, that got in their hands this device. My only problem is, how will this camera be created? My first idea was, that is just an enchanted camera (i don't know if there is a spell for this, i still need to get The Grand Grimoire), maybe it has a spell that makes it possible to exorcise the ghost, or maybe it can make incorporeal beings, corporeal (maybe they aren't ghosts).

The other idea, would be, that it's made of some sort of unknown material (maybe the lense, when it's used with a flash), that has the ability to make you see this creatures or ghosts. I'm also thinking, of giving them a limitation for using this device, maybe it needs batteries, or they need to change the film (maybe a polaroid?) Also, should they be ghosts or should i make some sort of creatures? Maybe related to a mythos creature.

Thanks, and sorry if my english isn't that good.
