35mm Film + Hydrochloric Acid = This!

2

We love all sorts of analogue experiments and this one by a Chemistry and Physics teacher from South Carolina is pretty damn cool. Check out the picture he tweeted of 35mm film dropped into hydrochloric acid! Can you guess what happened?

We here at Lomography love all sorts of experimentation on film, especially film soaks! From hot water to baking soda to laundry detergent, Lomographers love to get wet and wild!

So when we saw this tweet by MattAttackPro (a science teacher who possibly works for NASA launching rockets), we just had to share it with you!

“The beauty of chemistry! Soaked a piece of unused film in Hydrochloric acid.”

So what’s the lesson for today? When undeveloped 35mm film is dropped into a beaker of hydrochloric acid, the emulsion separates from its clear plastic backing. Yup, those yellow swirls are the coats and layers of light-sensitive salts suspended in gelatin that make up film’s emulsion (dull) side!

Warning: Don’t try this at home as liquid may be toxic. Also, it’s a waste of good film so keep shooting instead! ;-)

Sources include Boing Boing and PetaPixel.

The Lomography Color Negative 35mm 400 film delivers vibrant colours and superb saturation and contrast. You don’t have to worry while you’re shooting, even under low lighting conditions. See our selection of Lomography films here.

    I am a Mad Analogue Scientist: New Experiments with 35mm Films and Chemicals

    Unfortunately, it happens sometimes that your resulting pictures are not what you expected - the image doesn't look that good, the colors are bland, and the subject is banal. Indeed, it couldn't be picture of the year! Herein I propose a second chance for your pictures by modifying your 35mm negatives. Just pick up some ideas from here, experiment, and scan your negatives with the Lomography Smartphone Scanner. Anything is possible: burning, scratching, putting on hydrochloric acid, balsamic vinegar, nail polish, bleach, or raspberry juice... use your imagination and write down your new film soup recipe! You can find a sample of the effects in this article.

    Fourth of July Celebrations Throughout the Years

    On July 4, 1776, the redrafted version of Thomas Jefferson’s Declaration of Independence made it to Congress. Some 90 years later it was made into an official holiday. Since then, Americans have celebrated Fourth of July in full regalia. Some parade in flag-themed costumes or party in their best dresses, while others bond with friends over beer in the park.

    A Salute to the Masters: D-Day in Como? (A Tribute to Robert Capa)

    This article is dedicated to one of the most important masters of photography, Robert Capa. Capa is well known for his photos of war, from the famous image of the Republican Spanish soldier collapsing backwards after being fatally shot to his images taken in Indochina. He was also a co-founder of the famous Magnum Photo Agency, the first cooperative agency for freelance photographers worldwide. For this article, I took advantage of a rare event held in my city, Como, some weeks ago: a military drill for civil protection purposes.
