no, photographic films contains silver iodide which converts to gray-black metallic silver via photo reduction. Photo reduction is a light-dependent reaction which converts solar energy to chemical energy. when UV rays or visible light (basically sun rays) interacts with the silver chloride in the photographic film, photo reduction takes place.
try pouring some silver chloride on a piece of white cloth, then leave it out in the sun, the area where the silver chloride is exposed to the sun will become dark coloured.

Scorpions glow in the dark because of a substance in their exoskeleton that reacts to ultraviolet light, causing them to emit a blue-green fluorescence. This ability is thought to help them detect prey, communicate with other scorpions, and possibly protect themselves from predators.
Europium can be used in an assortment of glow in the dark paints. The metal itself does not glow.Europium:Symbol: EuAtomic Mass: 151.9Atomic Number: 63
TO prevent the siver halides from decomposition...as when it comes in contact of light the photo decomposition takes place.....BY- MOHIT GAUTAM
The word phosphorescence is a material similar to fluorescence but it does not give out light quickly. It does this because it slowly absorbs radiation.
This would consist of several series of lines corresponding to the energies of electron transitions. They are bright lines for an emission spectrum and dark for absorbtion.

Fluorescence agents are chemicals that emit light upon excitation. In the context of uranium glow in the dark items, such as glassware or jewelry, fluorescence agents are often integrated to enhance the glow by absorbing energy from UV light and reemitting it as visible light, resulting in a brighter and longer-lasting glow.
Tintype photos were popular in the 1860s to 1870s. This photographic technique involved creating a direct positive image on a thin iron plate coated with a dark lacquer or enamel. Tintypes were a relatively inexpensive and durable alternative to other photographic processes of the time.
if you eat carrots you can see in the dark.
Solarisation is a phenomenon in photography in which the image recorded on a negative or on a photographic print is wholly or partially reversed in tone. Dark areas appear light or light areas appear dark. The term is synonymous with the Sabattier effect when referring to negatives, but is technically incorrect when used to refer to prints.
If you weren't in a dark room, no.

If you are "in the dark," you do not understand something. The image is of a person fumbling around in a black space, trying to find something. The antonym of this is "to see the light," which means to suddenly understand. If you just don't know what something means, you could say "I'm in the dark on that subject, could you explain it to me?"
The plate is covered in a light sensitive compound, containing Silver Halide crystals. When light falls on the Silver-halide, it causes the silver atoms to clump together. When developed with chemicals, the silver is left behind, causing dark areas where light has fallen. This makes a negative image, where light is dark and dark is light. To get a positive print, simply shine light through the developed plate onto paper covered in the same Silver-halide compound. After the same chemical process, the picture is reversed again giving the positive image.
