LUTs

Oraphim's LUT browser includes technical and creative categories such as ACES, camera-log transforms, film looks, HDR ST 2084, and imported LUTs. A LUT is a fixed mapping; it does not know whether your source is correctly exposed, balanced, or in the color space the LUT expects.

Apply a LUT deliberately

1. Select the clip and the node that should own the LUT.
2. Identify whether the LUT is a technical transform or a creative look.
3. Confirm the expected input space before applying it.
4. Apply the LUT and inspect both the image and scopes.
5. Build corrective or creative nodes around it in an order you can explain and revise.

When OpenColorIO/managed color already performs the required technical source/display transform, do not add an equivalent technical LUT again. Double transforms are a common cause of contrast and saturation errors.

Practical example

For log-camera footage, first decide whether source conversion is handled by managed color/OCIO or by a technical LUT. Use one coherent transform path. After the transform, balance exposure and white balance, then add a creative look only if the shot needs it.

Verify

Bypass the LUT, inspect highlights and saturated colors for clipping, and verify skin/neutral material on scopes. Save/reopen and render a short review so the LUT path is proven in final output as well as the viewer.
