Film Simulator

NEW: Film-grade grain on export We replaced the previous digital-style noise with a proper film grain emulation — multi-octave fractal noise, per-channel layer sizes, and density-weighted blending. Exports now read as real 35mm grain instead of pixel-level static. Previews keep the fast path so the slider stays smooth while you dial it in. LUT Intensity goes up to 200% The slider now extends past 100% to amplify subtle film stocks. Default is still 100% (full LUT); anything above pushes the look harder without needing a different LUT. Smoother Contrast and Shadows We softened the per-unit response on both sliders. Small movements no longer blow out the image, so you get finer creative control at low values while keeping punch at the extremes. Real progress bar during export The export dialog now shows actual progress instead of an indeterminate spinner. Large files no longer look like the app froze.
