Developing my own photos 

NileRed is making chemistry both fun and educational at the same time, and it's so professional!

Your description of making coffee is very scientific.

I'm a photographer and I definitely wouldn't consider 22:48 underexposed. Even the pre-toned one looked acceptable to me. You definitely lost plenty of contrast and thus some detail in the highlights, but if you'd exposed it any more, I think you'd have lost the detail in the storefronts and buildings (which comprises the majority of the composition). I think it looks quite nice.

Is no one gonna talk about how cool the stuff looked when he opened the coffee grinder?

Here's something I learned from making my own printed circuit boards. You should ideally actually mirror the image and put the toner side down. That way, light won't come in from the side and creep in under the toner through the transparency. This helps keep lines nice and sharp.

I love how NileRed independently discovered Reciprocity Failure just based on his own observations

I absolutely love watching Nile red videos although I have no intention of reproducing any of these reactions or the facilities to try. I'm living vicariously through him.

In chemistry-based photography there is the idea of reciprocity, where exposing film or paper for twice as long at half brightness will give the same exposure. ISO 200 film at 1/500th second is the same as ISO 100 at 1/250th. But in really long exposures, on the order of above a minute, there is "reciprocity failure": a ten minute exposure isn't the same as a fie minute exposure one stop down. From your experiment it seems like that may apply to cyanotypes too.

Man this brings me back to highschool being in a dark room trying to figure out what the hell I did wrong. As a teenager this was pretty fun and we were dealing with the real chemicals back there....mostly unsupervised. Gotta love it.

I really love the trial & error aspect of your videos , it feels a lot more organic and is much more entertaining to watch since it's more of an amateur experiment then it is a lecture ( and i use the word amateur really loosely cause clearly you know your science ). That's why i love your channel and cody's so much , keep it up man !

Hey. When you are done with the photo and just about to frame it, put 2-3 coats of transparent varnish with UV filter. From my experience it does help a lot to keep the picture protected.

"A Cyanotype of your choice". Careful, NileRed... that's a dangerous slope. : P

It's not difficult to picture Nile Red as the wild West _photocopier_ dude with his horse drawn development lab travelling around amazing folks with his "magic" cyanotypes.

"You don't have to be like me and make the chemicals yourself, and you can often just order them online" Where's the fun in that?

"The Gayest Person on Patreon", "I'm sorry mistress" and "I'm SURE I can fit them all in my mouth" are the best names on your Patreon :X

I think the underexposed ones looked pretty nice!

If you found the cyanotype process cool you should try the daguerreotype process (also called "wet plate")! Its mostly silver nitrate and a developer bath. You get really beautiful images on metal plates!

You'll soon be doing old skool dodge and burn to adjust the exposure of individual parts of the image!

The experiment is in-depth and professional. It's hard to find videos on RU-vid with such quality. As always, great video.

In the final scene, did you just expose FAC coated paper and then brush on PF? That's allegedly how Herschel did it though we haven't tried ourselves. Very enjoyable series seeing you come at it from a different angle. If you try other recipes doing your first rinse in 1% Citric Acid lowers the contrast and helps other tones to the party. There are also a few published curves for Photoshop to adjust the tones for better representation. A Photoshop script called Chartthrob (Free) can be used to generate your own curves. Lastly, we never have luck making laser digital negatives. Inkjet is much better but make a test to see which color ink in your printer blocks the most UV. Reddish orange Canon inks work much better than black for us.

I love how methodical your videos are. Much respect, sir!

That Photo from Singapore is really something like taken out of time. The development just amplified that. In my opinion this is nothing short of a work of art.

alot of this i already learned from a black and white photography class, but its very interesting to see someone with no experience's take on it.

singapore represent babey!! i love the photo at 22:48 and all of the reactions/timelapses. this was so cool to watch i hope i get the time/opportunity to do this one day

More of this please! This perfectly ties up all of the videos you've done about dyes/pigments etc. Curious about other chemistry + photography connections, there isn't nearly enough good info out there like this video.

I been waiting for this one, it was worth it. I love the results, especially the non bleached and toned one, beautiful colour.

This is one of my favorite series you've done. As a photographer I love seeing the classic work you've done, as a nerd I love seeing how you're doing it. Bravo!

As a primarily analog photographer who specializes in this sort of photography, I really love and appreciate your interest in cyanotype and hope you decide to explore the chemistry of other photo processes as well, there's a lot of very interesting stuff that can be done in a darkroom.

I would love to see a video on 6,6'-dibromoindigo, AKA Tyrian purple. A very historically significant dye, and one that was incredibly expensive before it could be synthesized, due to how many snails had to be collected to extract a useful amount of it.

I very much love these practical applications of chemistry. Would love to see you cover more of these, including toning, in future videos!

the one you let sit directly in the tea looked the best! you could actually see the wetness of the rain on the tents!

7:30 "it can be a disaster" I actually sincerely enjoyed the rougher outcome more than the higher quality prints you produced later in the video; it gave it a lot of character that you lose with a perfect print.

I'm an artist and this video inspired make some prints! I ordered everything I need and can't wait to see how everything will turn out!!!

even the overexposed shot looked really cool..i LOVE the effects you are getting with this method!!

I always enjoy your videos greatly, but this one is, as of yet, my favorite video of yours. Some years ago, I started out with digital photography but not long after moved into film photography and darkroom processes, then followed by historical photographic processes. To see you go through step-by-step the recreating of what was done in the 1860s and on is quite fantastic. Trying to get the chemistry of the process properly working, to compensate exposure, to test different exposures and times of the day right for UV light, the way you test exposures by exposing the image for different times to check the density... You even got to the basis of density (Dmax) and reciprocity charts. It's all exactly what was and still is done in the making of a photographic print. *THIS* is the basis behind all the research and standardization in the photographic industry, creating UV-exposure units and emulsion-coating. It's what Kodak and Fuji, among many other chemical/photographic industries, did up until quite recently in 2004 when digital started to take over the market. As I said before, this is a fantastic work and video. Congratulations.

I wish my school chemistry lessons were this applicable.

"Tanin solution" Straight up cup of coffee 😆

22:48 that is just amazing!!! , i would never think twice before hanging this in my room , so good !

The one thing about Art is that even if these pictures aren't perfect, they're still beautiful. 😌

Would you mind uploading that photo from Singapore on imgur or something like that ? I really love photos like that with the rain and such

THANK YOU! i was going insane due to boredom this helps a ton.

This is outstanding. I'm getting ready to play with cyanotype (I got the premixed stuff), and all of your experimentation in this video got me all excited to get at it. Thank you for all this work.

As a person coming from the art side of this, I am quite impressed at what you accomplished in this series. It taught me more about the science of cyanotyping, and I really enjoyed seeing how you used the medium!

Also, I'd like to see more videos on early photographic processes. You still have all that mercury, right? Daguerrotypes, perhaps? (I may even be convinced to build you a simple camera for it in exchange for a beaker, I got a couple of old lenses laying around.)

My mouth dropped when you put it in the peroxide. I'm definitely making some of these!!!

What I really like about your videos is that the quality is so constant. As far as I can remember, your videos have always delivered and it makes me happy even seeing there's a new one to watch. It's a rare feeling these days on youtube. Thanks!

This is very satisfying to watch (development)

Here are a couple tips that I think could help. The negative is one of the most important things so you can convert the color image into a halftone first before inverting to a negative. This will allow you to adjust your levels more equally for just a single color exposure like your doing here or even for the duo tone. Also place the emulsion side of your negative closest to the paper, this will allow for less uv light to "bleed" under the blacked out portions which is a result of the very minute thickness of the transparent layer and you can also buy thinner transparency to reduce the amount of uv light to bleed. The closer you can get your negative to lay to the paper the better your result will be. In the print shop we vacume the negative down to the paper to get it as close as possible. Makes a huge difference. Also you could try a lower dpi "dots per inch" on the printer when printing the negative. Sometimes higher dpi washes out even though it's better quality some paper just can't hold it so try lowering the dpi to like 300 or 200 or 150 and see the difference in results. These are all things you can do that I feel would really help. I think it would be awesome to get some blueprints with lots of linework to expose. Like the Eiffel tower or the colleseum.

I bought a kit. I fell in love with the process and can't wait to try it myself. Thank you!

It’s important to note that the art paper is not only thicker and more durable but acid free which could likely help with the cyanotyping process

I am not gonna lie I nearly screamed when he said he took the photo in Singapore Singapore gang where y’all at

The non-linear exposure response over time has been known for a very long time in the film world. A specific example is film-make star trail images. If an exposure is made over 2 hours, the stars move, making a trail for each visible star. However, on film, each trail begins to fade out, as the exposure time / effect begins to diminish. This effect is called reciprocity failure, and is exactly what you describe here. Charts are/were even distributed to help photographers deal with the phenomenon on long exposures. www.ilfordphoto.com/wp/wp-content/uploads/2017/06/Reciprocity-Failure-Compensation.pdf

This video is truly awesome. I love the cool combination of chemistry and technology as well as your scientific approach to things. Brilliant!

You have an eye for photography too! Well done - I’ve really enjoyed this series.

You should consider a video about photoresist!

SCIENCE

Your videos are wonderful. Please keep making them!

Best run through of the cyanotype process Ive seen so far!

This is a very useful video. I have started trying to replicate your process since the previous video and this one adds quite a few helpful details! I loved the extra bit on toning the prints at the end, beautiful results!

Could you somehow mask part of the photo during the toning? Like block the sky so it stays blue while the subject turns brown?

I love this. Particularly fascinating to me since I've recently gotten into developing my own film and making prints (old darkroom equipment is super cheap right now).

Thank you very much for sharing your experiments with such a patience and attention to detail. Super helpful.

13:45, This graph does not show exponential, it shows rational, just for these math purists.

The cover of the Elliott Smith album "Elliott Smith" was done in cyanotype. It was the first thing that I associated with the thumbnail of this video.

After watching this video, the history of photography I learned about in my intro art class makes so much more sense!!

Your content is constantly high in quality and creativity. Looking forward to your next chemical exploration.

Great video! How do you recommend a lay person become competent in chemistry? I can’t afford to take a ton of classes outside my major, but I want to become knowledgeable at a high level in chemistry

You could have used these strips as a dosimete- Oh.

Wow, these just keep getting better. Bravo!

Been waiting for this last video for over a month now FINALLY

1:32 Yeah sure, “ferric ammonium citrate”

Hey nilered why don't you make iodoform?

This is my favorite of your videos. I just started shooting large format, and you've inspired me to try this with film negs

Hell yeah Nile! It’s good to see content from you :)

8:03 am I colour-blind? It looks greenish blue to me.

Careful with NordVPN, i saw Louiss Rossmann read there contract, it was really bad.

Loved learning about this. Ordered the transparency...will give it a try. Thank you so much.

Yess!! I was so excited for this video!

Will you be doing a video on making psychedelics from scratch for educational purposes (no, literally for educational purposes)

Science is cool

make more vids nile, i really like your channel bro, it's educational and absolutely fun to watch.

I’ve always been more into physics than anything, but your videos have really peaked my interest into chemistry again thank you

Too much of 'though'. Just an observation.

Early

That Singapore photo was perfect for this! All the prints of that shot were beautiful imho!

Prussian blue is so gorgeous, you did a fantastic job

1 view :O

I did that in college: we made iron-based photosensitive pigment and coated paper, then used that in a 4x5 box camera. I recall one student had a photo of a clock and you could see the motion blur in the minute hand, showing how the exposure was so slow.

Love this video and really explains the process well! Would love to see some more photography based videos! As a photo major I'm curious of the other photographic and even printmaking processes chemically

thank you so much for all the hard work!

This is the most artistic corner of chemistry 👍

really digging these photography themed videos!!!

I think it is my new favorite work of yours. Bravo!

Yess! Been waiting for this!

Yes! Art! I love seeing you do art!!!!

That was an amazing print of Singapore. Brings back some good memories.

Ooh this is artsy as heck!

Those custom beakers look really cool.
