Minimal RAW developer for Windows

Fukon

Develop your RAW photos straight from your folders. No catalog, no database, no fuss.

Always free

What is Fukon

Fukon starts from a simple idea: your photos already live in folders, so the program should simply work there. Open a folder, pick a photo, develop it. Your edits are saved in a small file next to the original (.dop), and ratings, colors and tags are also written to an .xmp file that other programs can read.

Your RAW files are never touched. The program is light, fast and made for people who want to focus on the photo, with a dark, neutral interface that does not bias your judgement of color.

Free. Always.

Fukon is freeware: free today and free tomorrow. No ads, no account, no subscription. If it is useful to you, you can support its development with a voluntary donation, but it is never required.

What it already does

All of this is already in the program.

Nikon and Fujifilm RAW

Nikon NEF and Fujifilm RAF files (X-Trans included), decoded with LibRaw and demosaiced at 16 bits per channel.

No catalog

You browse your real folder tree, with nothing to import and no database to maintain. Edits live in a .dop file next to each RAW; rating, color and tags also go to an .xmp file.

16-bit linear pipeline

Development in 16-bit linear ProPhoto RGB, with smooth zoom and pan up to 100% and beyond.

Basic adjustments

White balance in Kelvin and tint, exposure, tone, saturation and vibrance, plus texture, clarity and dehaze.

Curves

Luminance, RGB and single-channel curves with smooth, monotone interpolation.

Color grading and mixer

Color wheels for shadows, midtones, highlights and global, with blending and balance, and an eight-band hue, saturation and luminance mixer.

Detail

Sharpening with masking, luminance and color noise reduction, with a 100% view.

Geometry

Crop with aspect ratios, rotate, flip, straighten and perspective correction.

Local masks

Linear and radial gradients, brush, luminosity and color ranges, automatic subject detection; combine them by adding, subtracting and intersecting, and give each one its own adjustments.

Red eye

Click near the eye and Fukon finds the pupil.

Undo and before/after

Undo and redo for every adjustment, and a one-key before/after comparison.

Filmstrip and ratings

Fast thumbnails, stars, color marks, review status, tags and notes, all editable from the strip.

Metadata

EXIF with GPS, IPTC, ICC profile and the camera's maker note, read without loading the picture.

Interface in 5 languages

A flat, neutral-gray dark interface in English, Italian, French, Spanish and German, with live language switching.

Graphics card (experimental)

Optional drawing on the GPU with Direct3D 11, off by default and switched on in Preferences.

How it is made

Fukon is written in Delphi Professional with the FireMonkey (FMX) framework. RAW files are decoded with LibRaw, loaded as an external dynamic library.

Thanks

Thanks to the LibRaw team and contributors for their outstanding work (LGPL 2.1 / CDDL 1.0 license), to Embarcadero for Delphi and FireMonkey, and to the SQLite project.

What about macOS?

I develop on Windows and I have no Mac to build and test the program on. If enough donations arrive, I will buy a MacBook Pro and we will build Fukon for macOS too.
