A few years ago, a few people from Kolari Vision flew out to my place, and we tried exposing my autochrome plates in their potato pinhole. That batch of autochromes was a bit slow just with a regular glass lens, so exposures were absurdly long, on the order of 8 hours or so. It *technically* worked, but there was certainly quite a bit of room for improvement. They put together a nice little video on the endeavor that I would recommend.

[@Reddotzebra]

This was literally the first thing that came to my mind when I saw this potato-focused video about photography. "Hold on a second, are they going to talk about the Autochrome?"

yeah, the coolest part is that the thing that gives them the colour is also the thing that filters the colour going in, meaning that you can use it to take colour photographs in a monochrome camera

[@DatCupcake]

It's kind of a stretch, but there's also a type of color photography invented all the way back in 1903 called the Autochrome Lumière that makes use of potato starch. Making the plates is defintely a labor of love, but it's still cool to think you can take color photos with something you made in your garage.

As a biology student, I increasingly struggled with feeling like I had to find the one question or topic that I have a burning passion for, especially once I got into a PhD at an R1. I've come to realize that I'm driven by curiosity for everything and that focusing so narrowly on one topic just isn't right for me. A big part of that realization came from watching this channel. I've always been jealous that you have the ability to delve deeply into any question, regardless of field or discipline, and just pursue it doggedly until you're satisfied, then put it down. I've recently come to terms with the fact that I don't want to be an expert in a single topic, I want to be an expert jack of all trades. The thorough carefulness of your scientific techniques, ability to synthesize and distill knowledge, and excellent storytelling have been an inspiration to me for years

My biggest issue was that I'd study way too wide of a range of things instead of studying exclusively what would be on the test. So although I had learned an absolute ton, none of it meant anything, because I still got terrible grades, because it wasn't what was on the test. I fucking hate how our education system works, because it's built to make good workers, not to satisfy curiosity. Our education systems continuously fail people who have genuine deep curiosity, not because we can't keep up with the education, but because the education can't keep up with us.

A couple tips for curcumin anthotypes: 1) suspend the dye in gelatin, wet your watercolor paper, and coat the paper with a very thin layer of the suspension. Let dry. This will significantly increase your resolution, since you will have a denser and more even dye layer. 2) Before developing, wet your sensitized paper in ~10% H2O2. Keep it wet during development. This significantly increases the speed by which the UV light will develop the image. Using that method, I can develop an image of about 3x5” using the full frame of a 4,000 lumen DLP projector (really not the best tool for the job given the color wheel) in about 2 hours. Soak in normal water to remove the untreated H2O2 and then treat in a basic solution like you did. 3) Grab a transparent LCD meant for an SLA 3D printer. Use that for your exposures.

You can take a photogram with a leaf without applying photosensitive chemicals on it! Just treat the leaf like normal photogram paper, just with a much longer exposure time. The parts of the leaf exposed to the light undergo photosynthesis much more effectively than the covered areas of the leaf, which the illuminated cells store as starch. To develop the photogram, you just soak it in an iodine solution (both tincture & povidone work). The iodine reacts with starch to form a dark color, and an image pops out like magic! The awesome thing about this method is the leaf itself is the photosensitive component! The iodine only brings out the image that was already there, just hidden.

[@pseudomemes5267]

Little trick about silver nitrate stains. If you get silver nitrate stain on your skin you can remove it using iodine solution. It reacts with the silver making silver iodide which will be removed by your body faster than the silver metal.

The name stuck because of the traditional colour though the diazo ones were often more purple than blue.

Iodine turns starch blue, I thought that’s what you sprayed when the potato turned blue. Might be possible to create a light sensitive mask on the potato, expose it, wash off the unreacted stuff, then spray with diluted iodine to produce an image. Probably won’t be better than the cyanotype, but it’d be a neat experiment I guess.

[@xattakz2868]

I was thinking the same thing! Sodium iodide is somewhat light-sensitive, decomposing into free iodine, which can later react with more iodide iones to form I3-. That's the specie that is capable of reacting with starch to form the blue complex

I didn't expect to watch someone make a camera of potatoes, but I will watch it

[@Emile_Andre]

So as some people said, potatoes are the base of the autochrome process, invented in 1903 by the Lumiere brothers in Lyon (France). It is believed to be the first color photography process. The images are stunning and the resolution is great (I've seen some of them, it's really impressive). I'm not really sure how the process goes in details, but from what I know the starch is dyed with red green and blue pigments. It is then applied on a glass plate and a black and white emulsion (silver nitrate I guess) is applied on top of it. What is interesting though is that the Lumiere brothers realised that the resolution of the images was much better when the starch was crushed on the plate. So they had to invent a machine (the laminator) to industrially crush the starch evenly without breaking the glass. The pressure was something like 7 tons per square centimeter. If I remembrer correctly they won an industrial award only for the laminator. Anyway, I dream to be able to make autochromes prints one day, but from what I saw it's not impossible, but pretty difficult...

[@airiannawilliams3181]

None of this is my field of expertise, But I was thinking about the potato as film aspect. Perhaps if you were to take your sliced potato and cover it with smooth mashed potato it might actually work better, as a smoothe mashed potato shouldn't have as many pits in it when a thin layer is applied. Smooth mashed potatoes do end up with extra salt, butter, and milk added to it after it's peeled and boiled, then mashed till all clumps are removed. Either way, it makes for a nice side dish especially if you add a bit of cheese or gravy... Ooops, film. ;)

[@brooksvaughn4787]

The quality of the pin hole will make all the difference in image quality and exposure. In my early teens, I used the a flat peice of aluminum pie plate and placed a small dimple in the surface. Flip over and lightly sand with 1200 grit emery paper to remove the dimple to the desired pin hole size. This should be the side facing the photo sensitive medium. Attach the pin hole piece to the desired light tight apparatus (hollowed out potatoe). I preferred using oatmeal cartons as the camera body, which works outdoors since it was light tight. With the clear lids of today, place aluminum foil over the opening and hold in place with the lid.

From my own experiments with calotype photography (aka salt print), silver iodide is more sensitive than chloride and you can produce it using drug store iodine tincture, having an excess of nitrate in your plate helps sensitivity. Calotype paper can be developed with caffenol (a homebrew instant coffee-based developer) and the developer can be substituted with plain ammonia solution from the hardware store but I dont recommend this, it is foul. I just used it because stores in my country don't carry thiosulfate for some reason

@@thethoughtemporium This is a great video like all you have made. Adding a further warning somewhere (pinned post?) about silver nitrate in the eye would be beneficial to those that follow your experiments without further reading and understanding the dangers.

This whole video is cool, but I definitely liked immediately at the house hippo commercial. Best Concerned children's advertisers commercial

[@ethanmartinez808]

Hey man how's the neurons going?

[@monkeeet]

theyŕe still thinking, soo good i guess. Thanks for asking :)

[@akashashen]

You got my hopes up on that pin hole vs lens tease. I thought with all the KZbin videos of making various things like veggies and wood transparent, you had worked out a potato lens. De-brining the potato (ironic, as the potato is usually a debriner) and using a wire rack in that process, a long with a bottom draining pan, you were going to pull the whole thing together. Either way, it's better than the Packard Bell PC Buddy or whatever it was called in, like, 1996.

This man's content is just really really amazing and underrated

[@Lizlodude]

I love how many of your and Nile's projects seem to come from questions that you'd ask a buddy at 3AM, like can I take a photo with a literal potato or turn gloves into grape soda, and then spend weeks or months making it a reality. 18:50 r/brand new sentence

this fucking guy is always up to something. can't wait to see what he gets up to next

[@FroggyGamingV]

That commercial brought back so much as a Canadian child growing up up lmao

[@OmniversalInsect]

Potato AI when?

[@TheChzoronzon]

The "blueprint" etymology bit killed me... awesome!

don't kill me for this guys, i am an android user myself

it's exam season and instead of studying i'm now once again hyperfocusing on old timey photographic methods. amazing.

I WAS NOT EXPECTING THE HOUSE HIPPO APPERANCE BUT OMGGGG, as a fellow Canadian, the house hippo is a part of my soullll

[@Neptunium]

that`s a very cool project! and the blue picture results are very impressive! nice work!

[@minxythemerciless]

Seeing potato and blue image I was expecting that it was some starch / Iodine process. Maybe some future video?

[@ShiraCheshire]

I'd love to see an actual video taken with a potato. Could do it stop motion style and have like 10 FPS for maybe 3-5 seconds, then put it together in editing.

[@mintakamothkind]

My favorite version of that particular turn of phrase is "was this recorded on a pinecone"

More science supplies as merch is super exciting!

20:45 Silver nitrate is also used to cauterize serious nosebleeds. 🙃

[@KallePihlajasaari]

Yep, also for shaving nicks and removing warts back in the day. One has to be careful though, it is not called Lunar Caustic for nothing. Styptic pencil I think came later after the Caustic pencil.

[@user-jd1zj3bh2g]

Hey, I had an idea. You could get potato starch / potato flour and mix it with water and a binding agent and make thick potato papyrus. This could possibly be used as an alternative to the slab of potato you put on the back of your potato camera to achieve more consistent and more successful results. Just my two cents.

[@coughcpr3911]

I used to develop Panatomic-X with a direct positive method that, after the developer solution a very harsh wash was used to remove these exposed crystals. The film was then re-exposed to light, and a second developer was used to convert these previously unexposed crystals to black silver nitrate. I have no idea how Ilford managed to do that on paper,

[@williamwalters3796]

Awesome to see you make a video on this. When I was in my analog photography obsession I made a big camera for tumeric anthotype photos. Exposure time was days lol.

[@DeclanDoesCameraThings]

I'm loving all of these photography videos

[@kpturn42]

I would like to argue that your first attempt with the turmeric solution is the best illustration of the concept of “potato-quality image” 😂

[@clonkex]

I didn't realise how much I want to see you making custom, high quality film stock until today

This video was SO COOL!! I just want to say how SUPER PROUD I am of you. You do some of the coolest stuff. I truly enjoy learning from you. ❤

[@StephenPickells-bi2ii]

I heard a theory that the shroud of Turin is a photograph made by Leonardo in a camera obscura, basically a pinhole camera that you can get into. He made a statue and exposed it onto linen soaked in a silver solution
