1. Why Mac?

All our team members are photographers and initially we are creating Dehancer as a tool for ourselves, because almost all existing apps for digital processing make no sense when we talk about film emulation and simple and straight forward workflow for everyday use.

Being Mac users we’re using the operating system that is the main and only suitable for us in everyday life — MacOS.

This project is not commercial at present, so we don’t yet have financial and other resources to create and support the second development team for other platforms. However, we don’t abandon these plans in the future.

2. Which MacOS version is required to run Dehancer?

Dehancer runs on any Mac model starting from middle 2012 and later with MacOS Mojave installed. Please note that we do not officially support “hackintosh” devices because Dehancer intensively uses hardware. Yet it worth trying anyway.

3. Is it really free?

Yes, currently Dehancer is free. You do not need to pay for the app nor integrated film profiles despite their uniqueness.

Maybe some paid features will be added in the future but we’ll respect everything our users got for free earlier.

Perhaps we will also open donations if you’ll want to thank us for our work.

4. How to install and run Dehancer?

1.1. Please make sure you have a Mac starting from middle 2012 with MacOS Mojave installed and updated.

1.2. Download Dehancer from official site http://www.dehancer.com.

1.3. Unzip archive and put “Dehancer Desktop” file into the Applications/ folder on your Mac.

1.4. Double-click to Open the file.

1.5. If you see this message:

1.6. Please open Preferences on your Mac.

1.7. Open Security & Privacy options.

1.8. Allow to open App downloaded from dehancer site.

1.9. Enjoy.

5. How to update Dehancer and included film profiles?

After installing Dehancer, it will automatically download all actual profiles from our server.

When we add or update profiles they also automatically appear and update inside the application.

When we release a new version of Dehancer, it will automatically alert you to update itself, delay or skip this action.

6. Dehancer does not work after update. What to do?

You are using the alpha version and must be ready for program malfunctions after next update. If you are faced with this problem please open Terminal application on your Mac and clear the cache using two following commands step by step:

rm -rf ~/Library/Application\ Support/com.dehancer.desktop
rm -rf ~/Library/Caches/com.dehancer.desktop

7. How do the “ISO, Index” parameter works?

It is known that films show different contrast and colors depending on how they were exposed.

Each film profile in Dehancer contains multi-LUT (not simple LUT) format and in fact consists of three profiles made from different film exposures:

  • -2 Ev Underxposed
  • Normal Exposure
  • +2 Ev Overexposed

It’s possible to choose one of three exposures or any number between them using the “ISO, Index” parameter.

8. How do the “Expand” parameter work?

Usually, a scan from film (or print) is a low-contrast image that needs post-processing to make it look good on the screen. At the same time, some photographers prefer a low-contrast picture, because it looks more like analog print.

Dehancer allows both scan interpretations. As well as intermediate options in between. To achieve this we added the parameter “Expand” that automatically processes the photo similar to auto-levels (channel-wise), but more sophisticated and accurate.

Expand = 100 means you see a “film-scan” with auto-correction up to maximum digital contrast. Expand = 0 means you see “film-scan” as it is, without post-processing.

Default “Expand” value is set individually for each profile, usually it’s around 80-100. You can change it according to your creative needs.

9. Why do some black and white profiles have color cast?

Print targets for Dehancer profiles are printed from negative films in our own darkroom, and only after that we capture digital data from prints. Therefore our profiles reflect all what is seen on the print (including real paper tone).

Some targets (for example legendary “Kodak Eastman Double-X 5222”) are printed on famous  “Bromportrait” paper by Slavich Ltd. This paper is known for its noble warm tone, with different hues of bronze color in shadows, middles and highlights. It’s hard to reproduce this rich tone with digital tools.

If you don’t like paper hue, you may use Saturation = 0 at any time.

10. Image file formats compatibility

Dehancer is able to open and apply non-destructive corrections to the following image file formats:

  • JPEG
  • RAW (with optional RAW develop settings)
  • TIFF
  • PNG

Digital camera RAW formats supported:
