  <h1>Raspberry Pi Camera Tuning Tool</h1>
  <p class="sub">A web front end for creating libcamera tuning files for Raspberry Pi camera
    sensors.</p>

  <div class="card intro-steps">
    <h2>How it works</h2>
    <ol>
      <li><strong>Create a project</strong> — one per sensor or camera module, from the
        <a href="{{ url_for('projects') }}">Projects</a> page.</li>
      <li><strong>Capture calibration images</strong> — Macbeth chart images across a range of
        colour temperatures and lux levels, flat-field images for lens shading (ALSC), and dark
        frames for black level. Use the <em>Capture</em> tab with a connected camera, or upload
        existing DNGs on the <em>Images</em> tab.</li>
      <li><strong>Run CTT</strong> — generate a tuning file from the captured images.</li>
      <li><strong>Inspect and refine</strong> — review the generated parameters on the
        <em>Results</em> tab, and hand-edit values on the <em>Tuning</em> tab.</li>
      <li><strong>Preview</strong> — capture live images with the new tuning applied and compare
        against the current default.</li>
      <li><strong>MTF</strong> — optionally measure lens sharpness with a slanted-edge target;
        this is independent of the tuning run.</li>
    </ol>
