The Magic of Caffenol

[@lukeisafinename]

Completely forgot to put the research/recipe links in the description at first, but they're there now!

[@Isaacfess]

Thanks Luke!

During one of his recent videos on film development, Alec from the channel Technology Connections made an offhand comment regarding Caffenol. I thought that it was just one of his silly jokes until I got a notification for this video!

[@lukeisafinename]

I know just the video you're talking about. Big fan of his!

[@Ali-hu3tr]

I quite like the grainy photos tbh. Thanks for all the great videos this year :)

So glad Clint mentioned your channel in the old Cybiko video he did with you! It’s a shame I didn’t know about your channel until know! Really enjoying your channel so far! I have laughed quite a bit more than I was expecting, not really sure what I was expecting to be honest, but thanks for the laughs and the knowledge regardless😂!!! Really enjoying your unique style and humor! Going to have to binge watch your videos! P.S…Stupid question, and I know you must have been asked this a million times, so feel free to just ignore my question: “Are you and Clint twins?” Maybe a subscriber can fill me in on this one… sorry for asking 😂, just curious and it’s bugging me way too much, for me not to ask…

Loved the layed back format! And loved the history and exerment!

Ok, so, suggestions: 1.Try measuring by weight instead of volume, you'll have more repeatable results. 2.Soda first, then ascorbic, then coffee (chemically you want the soda and ascorbic acid to interact before coffee is introduced) 3.Try to get some potassium bromide (KBr). It acts as a restrainer, leading to much less base fog and smaller grain. 4.Per the Caffenol cookbook I do 10 inversions at the beginning and then 3 every minute. Total time for the BW films I've tried is around 15 minutes. What film did you use? I didn't have good results with any speed without the KBr. Too much fogging without it. Since starting to develop BW at home I have only used Caffenol and I'd be interested in a side by side comparison with rodinal as a baseline comparison but nobody has done that. When Intrepid send me my enlarger I'll also be able to judge the printability of my negatives. Will you do more Caffenol experiments? Sadly I haven't found anyone routinely using it or at least showing any familiarity with it on KZbin. Most try it haphazardly, get mediocre results and abandon it as a developer... Cheers from another Luke.

Oh and start with 20C water (68F)

[@lukeisafinename]

I've got so much coffee, vitamin c, and washing soda so there will absolutely be more caffenol content. Maybe some comparisons between developers, different films, etc. For this developing session, I used Arista 400, which is not my preferred film but it's what I had. Got some Kentmere 400 recently that I'll have to try since I'm much more familiar with how that stock is "supposed" to look. Thank you for the suggestions! I'll be sure to come back to this comment next time I try it out.

[@loukashareangas4420]

@@lukeisafinename According to one of the guys who did a lot of recent research on Caffenol, without any KBr you should only develop iso 100 and lower speed films. For higher speed you need the restrainer to keep fog down. Some have also reported good results with a generous amount of table salt in that role, though I don't know anything about it. Looking forward to what you do next!

Never have I clicked on a video so fast, now to watch the video!

You know, I usually despise grainy film. But honestly, I think these pics look really great! Congrats on the subs, and on the coffee negatives! Great stuff!

[@lukeisafinename]

Thanks! I'm pretty pleased with the graininess on display in a lot of these. Some of the ones I left out are, uh, a bit much though

[@stevenjlovelace]

Good point about the environmental impact. Developer seems like "chemicals" that are "bad" for the earth, while coffee, washing soda and vitamin C seem less scary.

[@GMCLabs]

Defiantly get a scale, spoonful's of powders can vary greatly just based on how ya scoop it. You'll defiantly have greater consistency going by mass. Pretty cool though!

[@gatsbye53]

My 2021 is made! 😁 Glad to see you gave this a try. Great video! I've got the fixings to give this a go too. Might give it a try this weekend. Take care & Happy New Year!

[@petronius100]

Please don´t let your camera strap dangle around like that on your F2! Cameras make those nasty sounds when crashing on the floor;-) Nice video btw!

[@TheStwat]

Very informative and enjoyable vid. Thanks.

[@theJellyjoker]

I've come to realize that "room temperature" water is actually "slightly chilled" water.

[@lukeisafinename]

Pretty much. Guess it all depends on what temp you like your rooms!

[@theJellyjoker]

@@lukeisafinename I live in Florida, so Ambiant room temperature is in the 70's.

Im here from your bro's channel and oh boy there are two of them nice

[@RanFuRe]

This is really cool. I never developed any film (other than way back in my schools photolab), but now I kinda want to ^^

[@c0ldsh0w3r]

I fuckin love it. Thanks.

[@LastofAvari]

Could cream help with coffee grainy-ness? ;)

[@lukeisafinename]

Ha! I mean you're more than welcome to try 😂

[@deedd4401]

science is pretty straight forward, consistent and systematic .. it's the english pronounciation that's not :D

[@NeedlessJ93]

Their study gave them some negative results, or actually positi... Gave them results 😁

[@dalehammond1749]

There is this great myth that shooting and developing film is simple. Taking pictures with a digital camera is simple. To do film consistently well takes a lot of study, practice, and money. It's always been this way. That's why they invented digital.
