Could you say that the dark image on the photographic film is due to fluorescence why?

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.

Why do you store silver chloride in dark coloured room?
TO prevent the siver halides from decomposition...as when it comes in contact of light the photo decomposition takes place.....BY- MOHIT GAUTAM
Image of emission or absorption spectrum of manganese?
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.
What two colors make a lava color?
i am thinking that maybe if you use dark orange with light red or light orange with dark red with a little touch of yellow it could make a lava colour
What colour do you get if you mix yellow and orange?
the colors vary depending on how much yellow or orange you put in.sometimes a soft/light orange or if you put in a lot of orange it could be a redish or dark dark orange color
Why do some tree roots glow in the dark when exposed?
This could be due to the phosphorus in the roots that is exposed to the air causing a chemiluminescence .

What are fluorescence agents in relation to uranium glow in dark?
Fluorescence is visible after UV irradiation; some substances as phosphates enhance the uranium fluorescence. Other substances can quench the uranium fluorescence.
Who discovered that wrapped uranium ore could develope photographic paper when stored in a dark drawer?
Henri Becquerel in 1896.
Can people with photographic memory have glasses?
if you eat carrots you can see in the dark.
What is solarisation in photography?
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.
Was i supposed to open my brand new pack of photographic paper?
If you weren't in a dark room, no.
What does the idiom 'in the dark' mean?
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?"
What is the pattern of dark bands on photographic film that is made when DNA fragments are separated by gel electrophoresis and tagged?
DNA fingerprint
How does Photographic plate work?
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.
What experiment will you conduct to identify the radation emitted by the uranium salt?
For gamma radiations: gamma radiometry, gamma spectrometry For fluorescence: irradiation with UV light in a dark room
