Dehancer is a suite of color grading software products that specialize in film emulation. It achieves this by digitally replicating the stages of analog image processing.

History

edit

Working with real film required a laboratory, which was challenging to find because, by the mid-2010s, photographic film was experiencing difficulties. Due to rising film prices and the increasing popularity of digital cameras, processing and printing images from analog media was becoming an increasingly untenable business. Handling film became a pursuit for film studios and enthusiasts.[1][2]

Dehancer has incorporated key concepts from earlier Photoshop actions[3] and applications[4] designed for image processing and the addition of various film simulation effects.

The company has developed its own engineering software for creating film profiles. This process involved extensive experimentation, including photographing color targets on film, developing the film, optically printing the images on both black-and-white and color photographic paper, and subsequently scanning the results.

The main goal was to imbue images with the look and aesthetics of real film, complete with all its characteristics - grain, bloom, halation, contrast etc.

The software is available as a plugin for photo[5] and video editors[6][7] and as a mobile application for smartphones.[8][9]

Technology

Film grain example

In Dehancer, film emulation is based on the principle of interpreting the image as consisting of grains, similar to real film where the image is stored in a layer of photographic emulsion. This approach allows the software to more accurately replicate the characteristics and aesthetics of analog film in digital images.

When photographing with real film, silver halide crystals react to light, either darkening or leaving parts of the image light. Different grain sizes, reflections from the camera or the film itself, and other artifacts — all contribute to a distinct film aesthetic that is unique and unmistakable.

Dehancer's approach involves breaking down the processed image into grains and then reconstructing it according to the selected film profile, based on a microcontrast map.

SREDA film laboratory[10] was selected for conducting the research. This laboratory specialized in processing, cutting, and repackaging photographic film (their own SFL brand) and possessed all the necessary equipment and specialists to support exotic processes.[11]

To achieve authenticity, film scanners were not utilized; instead, direct optical printing onto analog media was employed. The film was shot in three variations — normal exposure, underexposed and overexposed — to fully replicate the conditions of film. This is the only method to accurately interpret the negative and achieve the color rendition intended by the film manufacturer.[12]

To create specific profiles, the characteristics of historical films, such as Kodak Portra 160 or Agfa Agfacolor 100, were examined, and models were developed.

The adoption of presets has grown increasingly popular as film production diminishes and the cost of maintaining analog equipment escalates.[13]

Dehancer Online

edit

Dehancer Online is a simplified web-based version of the main Dehancer software. It provides users with a streamlined interface for applying film emulation effects to digital images.

  • Users can choose from a variety of film presets and image options based on print proofs.[14]
  • The application offers quick options for modifying brightness, contrast, and exposure.
  • Users can apply simplified versions of film effects such as grain, halation, and bloom.
  • Dehancer Online runs in a web browser, requiring only a stable internet connection.

This web-based tool makes Dehancer's core functionality more accessible to users who may not have access to or need for the full desktop version, while still providing the essence of film emulation capabilities.
