Video: Find out how Kodak develops and applies light-sensitive coating to its movie (at nighttime!): Digital Images Evaluation

Final yr, Destin Sandlin of the YouTube channel Smarter Each Day confirmed the science behind movie growth. Sandlin defined how photographic movie is constructed, uncovered, and developed. Sandlin mentioned the movie’s chemical construction after which shot some movie.

Sandlin loves movie. It has a particular, distinctive high quality that’s robust, if not inconceivable, for digital cameras to match. He will get his movie developed at Indie Movie Lab in Montgomery, AL. You’ll be able to see the lab at work within the video above.

Sandlin wasn’t happy explaining how movie works, so he kicked off a three-part Kodak manufacturing facility tour. Sandlin launched the first a part of his tour in March. In that video, seen once more under, Sandlin mentioned the primary of three main manufacturing phases of film-making, the movie base itself.

Sandlin’s first tour at Kodak’s manufacturing facility in Rochester, NY, was led by Matt Stoffel, a 3rd technology ‘Kodaker.’ Kodak was based in 1888 when George Eastman created the primary Kodak digital camera. The Kodak constructing Sandlin visited was in-built 1891.

Sandlin simply launched the second a part of his three-part Kodak tour, specializing in how Kodak turns the movie help and base we noticed made within the first a part of the tour into light-sensitive materials.

Completely different sorts of movie use totally different coatings. The variations in emulsion end in a variety of tones, grains, and general look of your pictures. In Sandlin’s tour, he sees how Kodak applies the light-sensitive coating to Ektar 100 movie. Ektar 100 is a coloration movie recognized for its extraordinarily superb grain look.

It could appear apparent as soon as you concentrate on it, nevertheless it’s superb to contemplate that the manufacturing facility course of for making use of a light-sensitive coating to a movie base have to be performed in full darkness. In any case, exposing the emulsion to mild whereas making use of it to the movie will spoil it. The method have to be carried out in pitch-black circumstances with minimal human intervention. Whereas individuals are closely concerned in numerous steps within the movie base manufacturing course of, turning that movie help right into a usable movie requires a unique strategy.

The coating have to be utilized moist, too, which makes it very fragile. It additionally have to be dried with out being broken. The purpose is that there are loads of potential issues alongside the way in which. Kodak offered Sandlin with totally different engineering drawings exhibiting its movie coating facility, which he and his group then was 3D fashions. It is an extremely intricate, advanced course of performed in whole darkness, making it much more spectacular. ‘When you perceive how this facility works, it makes taking pictures with the movie even that rather more rewarding.’

Every layer of light-sensitive materials utilized to the movie help might be delicate to or filter out particular mild wavelengths. The totally different layers work collectively to make a movie that may report a full-color picture.

As a part of his tour of the Movie Sensitizing Division at Kodak, Sandlin met with Dr. Jeffrey Hansen for a few days. Hansen has been engaged on movie for over 30 years and is without doubt one of the world’s main movie design and manufacturing consultants. Hansen additionally explains the bodily construction and chemical composition of the light-sensitive layer of movie. The chemical construction determines the kind of movie and the way it works.

Whereas we do not wish to spoil the tour – and you need to watch your entire hour, particularly in the event you’re a movie pictures fanatic – the essential mechanical course of is sort of advanced. Keep in mind, that is all performed at nighttime. First, machines unwind the movie help base that we noticed produced within the first tour video. The help is then coated with gelatinous materials with suspended silver halides. It is moist, so it have to be solidified by chilling. It is then dried. The coated base is then coated with one other layer, chilled, and dried earlier than being rewound.

To see extra footage, Sandlin has uploaded further materials on his second channel. The primary video is about Kodak’s movie high quality management course of. One other supporting video is targeted on the chemistry of Kodak movie.
