White balance values are estimates. Low confidence usually means the frame lacks neutrals or is heavily stylized.
1. Load an Image
- Drag a JPEG or PNG into the upload area, or click it to browse.
- Use Upload Another Image to switch files anytime.
2. View & Grids
- Image is letterboxed inside 800×450 preserving aspect ratio.
- Toggle Rule of Thirds overlays a 3×3 grid.
- Toggle False Color overlays exposure bands.
3. Histogram & Scope
- Left is shadows (0), right is highlights (255). Switch Curve/Bars and Linear/Log.
- Vectorscope scale toggles 1x or 0.5x.
4. White Balance
- WB is estimated in Kelvin by sampling near-neutral midtones in linear space and mapping to CIE CCT. Clamped to 1800–12000 K.
- No changes are applied to the image.
5. Palettes
- Extracted up to 18 dominant colors; export PNG or TXT.
- Custom pick colors into 18 slots, copy from extracted, export PNG.
