Chemistry Behind Film Photography

[@mrsnulch]

Who thought this adorable school project would be the best video on film on KZbin lol! Hope you guys got 100% - although maybe I’d deduct a mark for saying there aren’t any negatives switching to digital. FILM PHOTOGRAPHY FOREVER!

[@prathameshhalade8230]

Yeah I mean they got a good pun there and nice video btw, but the intimacy of film photography cannot be replaced. It's like mass produced commercial goods vs delicately and intimately created piece of artifact.

[@nativesun7661]

But they were being deliberately sarcastic. Full 100% still!!

[@Fishies125]

Was this a school project? Either way, very informative; I learned exactly what I needed!

[@BrianPLawler]

Film negatives are not processed in red light. They are processed in total darkness. Film is panchromatic, meaning it’s sensitive to all colors. Photographic paper is orthochromatic, making it insensitive to red light. So after the negative is developed and fixed, you can move to a red light darkroom to make prints. For color photography, it all has to be done in total darkness.

[@Morgott2nd]

Unless you are photographing on ortho film, as it is still produced. It's much less common nowadays, though.

[@GanjaBro99]

Holy mother, I hope you get an A+ for this presentation. Very concise and informative, good job!

[@worminator15]

Wow that's literally just basic redox chemistry Thanks for the compact and well presented video

[@phandinhthanh2295]

Developing photographs back in those days seems like an art.

[@DavesFilmLab]

Just have to point out, the mention of red light in the darkroom is not entirely accurate. A red light can only be used if the film is orthochromatic. Most films, both black / white and color, are panchromatic and hence, would be exposed by the red light. Most black and white paper is orthochromatic, but very few film stocks are. All this said, still an exceptional video.

Awesome 👍 and informative.... 🤭🤭🤭Fun-fact: At 3:35 I spot one our you smiling and giggling coz the other stutter a bit🤭🤭 Happy to see you guys are enjoying your work and having fun.

good observation lol

[@coleymissions]

this is the best photography video on KZbin.

[@Dodl1]

Finally a video that explains me what actually goes on there. Thank you!

[@dmytrochaika7570]

Great video! One small caveat: the vast majority of modern black&white films ARE sensitive to red light too. So they should only be processed in TOTAL darkness. Red light will destroy them. This is not the case for photographic paper though, and a few select filmstocks that are called orthochromatic. In the past, there were a lot more orthochromatic filmstocks.

This was really helpful, like honestly this is so useful thank yoou

[@h.h_team2660]

The explanation was great,.👌 I could really understand the topic in simple terms.

[@pianoslayer2516]

Why is an emulsion necessary? My understanding is that it's the crystals suspended in the gel, which are silver bromide in this video, that react with the light. In that case, why do you need the gel?

[@VivekKumar-op7sc]

I really wish if you make more videos like this ...

[@prajeethk4348]

Awesome. The animation helps as well. Very good job. Thanks...

Lol.. love it! Great job ladies!

This is so useful thanks a lot for clearing my concepts about this topic

This is very in-depth. Thank you for this knowledge

[@SHDEdits]

BRO what kinda school project is this. Bravo

[@hemaurr]

thank you so much for this!

"there aren't any negatives"

*badum tssss*

[@BboyGraphicx]

Thank you for making this, brilliant!

[@phonybuddha5999]

So photos with longer exposure times take a shorter time to develop?

[@sethreissig1391]

Not necessarily. For example if you use a 1 stop longer exposure time with the aperture stopped down 1 notch then the actual amount of light collected on the film is equal to the amount of light collected if you used 1 stop faster shutter and 1 stop wider aperture than the previously described situation. The goal for perfect exposure actually has to do with how much light you collect. Too much light = overexposed, which means if you develop it for the same amount of time as all the other exposures on the film roll, it will be way too bright. (if the other exposures are perfectly exposed.)

[@charleshines2506]

I have a digital camera but many phones come with really good cameras also. While phones don't always take the best images you would have to look closely to see that really.

What a cute video -- and helpful!

[@manikduggal]

When the film is exposed to light , Ag+ is reduced in those particular regions exposed to light , then what is the requirement of a developer solution ??

keep postin

[@samiranphukan8441]

If we dip the film in developer solution then why fixer?

[@annagizziatlas62]

It prevents the negative from changing from additional light exposure. You could take it out in daylight and it wouldn't change the image on the negative. (can others confirm?)
