The door to the Muggle Studies classroom stands open, though no adult is in sight to bid you welcome.

Something else, however, is far more likely to capture your attention. Across the corridor, above the door of the room opposite the classroom, a peculiar red light glows steadily, bathing the surrounding stonework in a faint crimson hue. It is difficult to remember ever seeing it before. Had it always been there, unnoticed? And if so, why was it glowing now?

Walking inside the classroom, instructions written across the whiteboard can be read:

Before taking your seat, please collect the following materials:

• 1 pair of nitrile gloves (put these on immediately)
• 1 pair of safety glasses
• 1 film protector sheet
• 1 pair of scissors
• Your processed negative film strip

An arrow beneath the list points toward a table beside the board. Several bins have been neatly arranged there, each containing the required supplies. Gloves are sorted by size, safety glasses are stacked in orderly rows, and scissors rest in a small plastic crate.

To the side, a heavy curtain conceals part of the classroom. Behind it, a clothesline stretches from one wall to the other. Hanging from it are strips of developed camera film, each clipped in place and labelled with masking tape bearing a student's initials. Tiny images are visible within the dark negatives—familiar faces, pets, castle corridors, the grounds, and countless other moments students have chosen to capture.

Once you have gathered your materials, go ahead and get settled into your seat. The lesson, led today by a guest lecturer, will begin shortly.

OOC: Students in Muggle Studies with Professor Berry (NPC) have been exploring a variety of Muggle inventions, with the most recent lessons focusing on cameras and the art of photography. Each student was provided with a mechanical film camera and tasked with documenting moments of life at Hogwarts that could be included in the school's time capsule. During the previous lesson, students learned how exposed rolls of photographic film are processed into strips of developed negatives. Today's lesson, under the guidance of a guest lecturer, will showcase how images preserved on film emerge as finished photographs.
