  DarkRoom 0.7.0 — Film simulation Stable

  dtourolle released this 2026-08-26 16:14:23 +00:00 | 929 commits to master since this release

  Film simulation, and the library that can keep up with it.

  Film simulation

  DarkRoom now renders a film stock from that stock's own measured
  characteristic curves rather than from someone's approximation of the look.
  The stock is chosen per photograph and remembered with it.

  • Five Ilford stocks — Delta 100, Delta 400, FP4 Plus, HP5 Plus and
    Pan F Plus — alongside the colour stocks. The profiles state plainly
    that they are constructed rather than measured, so nothing here claims
    an authority it does not have.
  • Grain counts silver instead of adding noise on top: density drives
    the grain, so it behaves the way the stock does rather than the way a
    noise generator does.
  • Black-and-white negatives are printed rather than shown as a scan,
    and development runs from the measurements rather than a contrast slider.
  • The whole stock renders on the GPU and takes over the render path, so
    choosing a film is not a reason to wait.

  Library

  The grid stopped re-answering the same questions every time the window
  moved. It pages along an index rather than re-sorting the library, loads
  the window around the whole view instead of its first cell, and fetches
  what is on screen before what is not. Shift-click now takes the whole run
  it names rather than the part that happened to be loaded, and shows which
  cell it is measuring from.

  Build and CI

  Most of this is invisible unless it was broken, and it was.

  • The segmentation model reaches CI again. Git LFS was being sent two
    Authorization headers and Gitea answered 400; the Android image had no
    git-lfs client at all, and then no file(1) for the API-level check.
  • The Android build produces an installable APK, assembled by the same
    script package.sh uses locally, and signs it with a real key when one
    is configured — see docs/android-signing.md.
  • The test build stopped filling the runner's disk: no debug info, no
    incremental state, 24 GB down to 3.3 GB.
