When it absolutely, positively, has to be photographed overnight!
Created from a version of a personal spell, Anatoli’s Image Preserver, this device creates photo on a piece of Vellum loaded into the back. However, the image will fade with time, just like the version created via the spell, unless a specially prepared lacquer is applied.
While many copies have since been made and spread through gnome-dom as charged magic items, Anatoli retains the Prototype. Unexpectedly the prototype does not suffer from the charge limitation, and no application of lacquer seems necessary.
