Third-party material

This product bundles third-party material under its own licenses, listed below. The per-file
list (author, source, license) is in assets/ATTRIBUTION.md.

Inter (assets/fonts/Inter-*.ttf) — SIL Open Font License 1.1. The licence text is
assets/fonts/OFL-Inter.txt in the source tree; release packages ship it beside NOTICE as
OFL-Inter.txt (Windows installers include it in FONT-LICENCES.txt).
Showcase photographs by Ansel Adams, Dorothea Lange and NASA (docs/images/) — public domain. See assets/ATTRIBUTION.md.

crates/raw/src/spectral_table.rs (lightcraft-raw) holds camera colour matrices derived from the
camera spectral sensitivities, training reflectances and model alias list of rawtoaces-data
(https://github.com/AcademySoftwareFoundation/rawtoaces-data, v1.1.0), an Academy Software
Foundation project licensed under the Apache License 2.0, and from the CIE 1931 colour-matching
functions it ships (CIE, CC-BY-4.0). The matrices were fitted by the LightCraft contributors
(2026) with tools/spectral_camera_table.py. See assets/ATTRIBUTION.md.

crates/inpaint (lightcraft-inpaint) ports the inpainting (PatchMatch completion) and Poisson membrane
fill code of PhotoCraft (https://github.com/storytold/photocraft, crates/algo/src/inpaint.rs and
poisson.rs), Copyright the PhotoCraft contributors, licensed under the MIT License or the Apache
License 2.0, at your option. The port was modified by the LightCraft contributors (2026); each
ported file says so.

crates/segment (lightcraft-segment) ports the SAM 3 model code of Hugging Face Transformers
(https://github.com/huggingface/transformers, src/transformers/models/sam3 and sam3_tracker),
Copyright The HuggingFace Team and Meta Platforms, Inc., licensed under the Apache License 2.0.
The port was modified by the LightCraft contributors (2026): translated from Python/PyTorch to
Rust on candle and restructured; each ported file says so. Because of this, crates/segment is
licensed under the Apache License 2.0 only (LICENSE-APACHE), not under the MIT option.

The SAM 3 weights are not part of LightCraft and are never distributed with it. A user downloads
the facebook/sam3 checkpoint only when they choose to (in the app, or by hand), under Meta's SAM
License (https://github.com/facebookresearch/sam3/blob/main/LICENSE), a separate, non-OSI
licence. See docs/ai-masks.md.

AI denoise weights are not part of LightCraft and are never distributed with it.
The default build offers user-supplied models only. The optional rawnind-model
feature offers a separately downloaded RawNIND UtNet2 Bayer checkpoint under
GPL-3.0 (https://www.gnu.org/licenses/gpl-3.0.html), after the user accepts its terms.
Commercial use is subject to those terms, including applicable source, licence and
notice obligations on redistribution. Enabling that offer in releases remains a
maintainer decision. The ONNX reader and CPU/GPU executor are our Rust implementation;
no darktable, RawSpeed, LibRaw or other GPL decoder/runtime code is included.

Builds made with craft-fonts (the optional CRAFT_FONTS_DIR build input; all official releases)
also embed the default fonts listed in
https://github.com/storytold/craft-fonts/blob/b076417b5880bd4154bd22f00695b1d28c6bea83/ATTRIBUTION.md (BIZ UDPGothic, BIZ UDMincho,
Shippori Mincho, Noto Sans CJK SC, Noto Sans Arabic, Noto Sans Thai, Noto Sans Georgian,
NanumGothic, Noto Sans Symbols, Noto Sans Symbols 2, Noto Sans Hebrew and
Noto Sans Devanagari), under the SIL Open Font License 1.1. The opt-in LXGW WenKai Lite face
(fonts/simplified-chinese-manifest.txt in craft-fonts) is not embedded. The web build embeds
BIZ UDPGothic Regular, Noto Sans Thai Regular and Noto Sans Georgian Regular, and loads Noto Sans
CJK SC separately. Release packages include each font's licence as OFL-<family>.txt; Windows
installers include their texts in FONT-LICENCES.txt.

Place names for reverse geocoding (Photo > Fill Location from GPS) are not part of LightCraft and
are never distributed with it. On the user's request (Photo > Download Place Names) the app
downloads cities15000.zip, admin1CodesASCII.txt and countryInfo.txt from GeoNames
(https://download.geonames.org/export/dump/) into the settings folder. GeoNames data is licensed
under Creative Commons Attribution 4.0 (https://creativecommons.org/licenses/by/4.0/);
attribution: "GeoNames, geonames.org". The lookup code (crates/geocode) is our own.


epaint_default_fonts, the egui default-font crate LightCraft builds with, also bundles Hack Regular
and Ubuntu Light, and Noto Emoji Regular when egui's `monochrome_emoji_fonts` feature is on (the
LightCraft workspace enables both `default_fonts` and `monochrome_emoji_fonts` on egui 0.37). The
LightCraft binaries embed these faces unmodified, registered through egui's default font definitions.

Ubuntu Light (Ubuntu-Light.ttf) is Copyright 2011 Canonical Ltd., was designed by Dalton Maag Ltd,
and is licensed under the Ubuntu Font Licence 1.0 (not the SIL Open Font License).
The following text is reproduced verbatim from UFL.txt; that file carries no copyright line, so the
copyright notice above is taken from the font's own name table:

-------------------------------
UBUNTU FONT LICENCE Version 1.0
-------------------------------

PREAMBLE
This licence allows the licensed fonts to be used, studied, modified and
redistributed freely. The fonts, including any derivative works, can be
bundled, embedded, and redistributed provided the terms of this licence
are met. The fonts and derivatives, however, cannot be released under
any other licence. The requirement for fonts to remain under this
licence does not require any document created using the fonts or their
derivatives to be published under this licence, as long as the primary
purpose of the document is not to be a vehicle for the distribution of
the fonts.

DEFINITIONS
"Font Software" refers to the set of files released by the Copyright
Holder(s) under this licence and clearly marked as such. This may
include source files, build scripts and documentation.

"Original Version" refers to the collection of Font Software components
as received under this licence.

"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to
a new environment.

"Copyright Holder(s)" refers to all individuals and companies who have a
copyright ownership of the Font Software.

"Substantially Changed" refers to Modified Versions which can be easily
identified as dissimilar to the Font Software by users of the Font
Software comparing the Original Version with the Modified Version.

To "Propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification and with or without charging
a redistribution fee), making available to the public, and in some
countries other activities as well.

PERMISSION & CONDITIONS
This licence does not grant any rights under trademark law and all such
rights are reserved.

Permission is hereby granted, free of charge, to any person obtaining a
copy of the Font Software, to propagate the Font Software, subject to
the below conditions:

1) Each copy of the Font Software must contain the above copyright
notice and this licence. These can be included either as stand-alone
text files, human-readable headers or in the appropriate machine-
readable metadata fields within text or binary files as long as those
fields can be easily viewed by the user.

2) The font name complies with the following:
(a) The Original Version must retain its name, unmodified.
(b) Modified Versions which are Substantially Changed must be renamed to
avoid use of the name of the Original Version or similar names entirely.
(c) Modified Versions which are not Substantially Changed must be
renamed to both (i) retain the name of the Original Version and (ii) add
additional naming elements to distinguish the Modified Version from the
Original Version. The name of such Modified Versions must be the name of
the Original Version, with "derivative X" where X represents the name of
the new work, appended to that name.

3) The name(s) of the Copyright Holder(s) and any contributor to the
Font Software shall not be used to promote, endorse or advertise any
Modified Version, except (i) as required by this licence, (ii) to
acknowledge the contribution(s) of the Copyright Holder(s) or (iii) with
their explicit written permission.

4) The Font Software, modified or unmodified, in part or in whole, must
be distributed entirely under this licence, and must not be distributed
under any other licence. The requirement for fonts to remain under this
licence does not affect any document created using the Font Software,
except any version of the Font Software extracted from a document
created using the Font Software may only be distributed under this
licence.

TERMINATION
This licence becomes null and void if any of the above conditions are
not met.

DISCLAIMER
THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF

INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM OTHER
DEALINGS IN THE FONT SOFTWARE.

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font
creation efforts of academic and linguistic communities, and to
provide a free and open framework in which fonts may be shared and
improved in partnership with others.

The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply to
any document created using the fonts or their derivatives.

components as distributed by the Copyright Holder(s).

components of the Original Version, by changing formats or by porting
the Font Software to a new environment.

writer or other person who contributed to the Font Software.

binary files as long as those fields can be easily viewed by the user.

3) No Modified Version of the Font Software may use the Reserved Font
Name(s) unless explicit written permission is granted by the
corresponding Copyright Holder. This restriction only applies to the
primary font name as presented to the users.

4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
Software shall not be used to promote, endorse or advertise any
Modified Version, except to acknowledge the contribution(s) of the
