VSCO Went Full MacGyver to Create an Authentic Kodachome Film Simulation

Last month, VSCO achieved a years-old dream of releasing a preset/filter that was based on Kodak’s iconic “Kodachrome” film stock. But creating the KC25 preset was anything but easy. In fact, it involved custom chemicals, custom hardware, and two years of experimentation to get this one right.

You see, when the folks at VSCO (formerly “Visual Supply Co.") set out to create one of their film simulations, they usually start with the actual film. Just one problem: the last roll of Kodachrome was processed in 2010, one year before VSCO was founded.

“We had made some eyeballed attempts based on historical film scans, but releasing a film preset that wasn’t built from real film didn’t meet our quality standards,” explains Kyle Hale, Senior Product Operations Specialist at VSCO, in a blog post titled Reviving Kodachrome. “Thus, the desire to find a way to create a digital version of Kodachrome from developed Kodachrome film remained dormant in our minds.”

Then, in 2017, the mad scientists in the VSCO lab decided to pick up some expired Kodachrome off of eBay, throw it in their fridge, and begin the long and arduous process of re-creating the developing process in-house.

The main challenge with recreating Kodachrome isn’t so much getting the film itself, it’s the incredibly complex developing process involved in turning the film—which is actually a black and white emulsion—into the final product that produced such iconic and strikingly colorful shots as Steve McCurry’s Afghan Girl.

“The process to develop Kodachrome, known as K-14, involved approximately 14 steps to develop the film,” explains Hale. “This process was comparable to how an inkjet printer applies cyan, yellow, and magenta dyes to a piece of paper to form a final color image.”

Since the exact chemicals used in the K-14 process are no longer in production, VSCO had to create them in-house. What’s more, they had to develop a detailed, automatic, and consistent process by which to test their work so that they could iterate their way to success.

“Progress was slow and tedious, as each run of a small strip of film took hours to process by hand in the dark,” says Hale. “Because of the myriad of variables, we were only able to run about 10 tests a week.”

Initial tests “fell flat,” explains Hale. As mentioned above, the process is incredibly complicated and their first attempts produced images with low contrast and poor density in the film. But, as time went on and their formulas improved, so did their results.

“After months and months of iterations in our experiments and roll after roll of Kodachrome developing, we finally achieved results for Kodachrome that we were proud of,” writes Hale. “We achieved acceptable film density (Dmin and Dmax), acceptable overall color balance, and consistent results on the same batch of film.”

You can see the final results below—from dye tests, to the final product:

This is how VSCO ultimately achieved many a photographer’s dream: they can now successfully process Kodachrome film. It’s also how, 10 years after the last roll of Kodachrome was developed, the company was able to release its “KC25” preset based on actual Kodachrome that they actually developed in house.

To the uninitiated, two years of tinkering, creating custom chemicals, and building custom hardware might seem like a lot to go through in order to create a film preset. But when it comes to a film as iconic as Kodachrome, there really is no other way. Kudos to VSCO for doing something awesome.

But of all the games, I prefer the one about the other Asterion. I pretend that he comes to visit me and that I show him my house. With great obeisance I say to him “Now we shall return to the first intersection” or “Now we shall come out into another courtyard” Or “I knew you would like the drain” or “Now you will see a pool that was filled with sand” or “You will soon see how the cellar branches out”.

amazing article

I cannot remember all the details. But I remember one peace conference with the French where the Vietminh were not invited. On Sept. 14, when ho signed this basically hollow document, he was heard to murmur, “I am signing my own death warrant.” But to a colleague he concluded, “there is noting else to do but fight.” Ho returned to Vietnam, but then fighting broke out in Haiphong, Mus said, that Ho had been betrayed, adding, “I use the word betrayed with full knowledge of what it means.” After that, Ho never placed faith in negotiations.

At one point, Ho went to Paris for talks again, but the French put him aboard a very slow ship while behind He’s back, they tried to install a French puppet government in his absence.

before my German friend left, we went to the place called “12 tables” to eat spas, amazing Armenian soup made from matsoun. I love it so much that I eat it every day. (:

When we were leaving it was late, the place is already closed. It somehow happened that we got acquainted with the owner (she also works there together with one assistant). She started discussion by noticing Mommintroll on my backpack. It turned out she’s from Artsakh. She said her mother was grown up and educated in Baku, and she does not know Armenian well. She married her father and moved to Martuni. They left it during the war, in 1992. By helicopter which took them to Yerevan. She described how they reached the helicopter in the night. She said “the toilet was in the courtyard, and we could not go to the toilet, because azeris would shoot us.”.

Then they moved to Poland, because they had relatives there. She returned to Yerevan several years ago, she spoke only Polish and Artsakh dialect of Armenian. She learned literate Armenian, the alphabet, and the grammar. She opened one of the best places in Yerevan, cafe-flat, with very tasty dishes. She’s proud she eventually made it completely smoke free.

She does not know if she’ll live here in the future. Because it’s not easy, even if you have business. I hope she will. Her assistant turned out to be a girl from Artsakh who came to study in Yerevan.

Her parents come to Armenia from time to time, but they don’t stay in Yerevan, they go to see their home in Martuni. “In Poland they live in rural area too.They don’t like big cities, many cars and noise” - she explained.

Once upon a time a boy have noticed that one of the games can turn off the power LED on his Amiga. There were two LEDs on Amiga, he could manage the other, but not this one. He didn’t even know it’s possible.

Boy could not live calmly until he found out the way to manage the LED. Then he lived happily ever after. (:
