How to apply a LUT in Lightroom.

Updated November 6, 2026

In Adobe Lightroom Classic, creative looks usually land through the Profile Browser in Develop—not through Photoshop's Color Lookup → Load 3D LUT dialog. A free-standing .cube is most reliable as an imported .xmp profile (often converted from the LUT with a free tool), or by applying the .cube in Photoshop Color Lookup / DaVinci Resolve on a Rec.709 still or timeline. Lightroom (cloud desktop) likewise leans on profiles rather than a native Load 3D LUT path.

Before you start

• Unzip the download so you have a real .cube file (not a .zip).
• If the source is log, convert to Rec.709 before any creative look. See Log vs Rec.709.
• Decide the delivery app: stills destined for Lightroom-only delivery often use a profile; mixed stills/video pipelines often keep the .cube and apply it in Photoshop or Resolve.
• Prefer 33-point cubes for everyday social work; keep a 65-point copy if soft gradients matter.

Step 1: Pick the honest path for your file

1. Profile path (Classic): if you already have an .xmp Develop profile derived from the look (or you convert the .cube to a profile with a free third-party converter), use Profile Browser → Browse / import that profile. Classic expects profiles, not a Photoshop-style Load 3D LUT picker.
2. Photoshop path (still / frame grab): export or open a Rec.709 still, then Layer → New Adjustment Layer → Color Lookup → 3DLUT File → Load 3D LUT…. Full steps: How to apply a LUT in Photoshop.
3. Resolve path (video): load the .cube in Color as a LUT node or timeline LUT after the technical conversion. Full steps: How to apply a LUT in DaVinci Resolve.

Step 2: Lightroom Classic Profile Browser (when you have a profile)

1. Select the photo and open the Develop module.
2. In the Basic panel, click the Profile Browser control (four rectangles next to Profile).
3. Use Browse to review installed Creative / Camera Matching / custom groups.
4. Import or install a custom .xmp profile when your converter or vendor provided one. Then choose that profile for the selected photos.
5. If you only have a raw .cube and no profile, do not hunt for a missing Load 3D LUT menu in Classic—switch to the Photoshop or Resolve path above.

Step 3: Lightroom (cloud) vs Classic

• Lightroom Classic is the local-catalog app with deeper folder and plugin control.
• Lightroom (cloud) syncs libraries to Creative Cloud and also applies looks via profiles—not via Photoshop Color Lookup.
• Neither product is the same UI as Photoshop Color Lookup. Treat free-standing .cube delivery as Photoshop/Resolve-first unless you have a matching profile.

Step 4: Strength, order, and a short test

• Keep exposure and white balance sensible under the creative look; do not stack two heavy creative profiles.
• If you used Photoshop Color Lookup, lower layer opacity when skin or mixed lighting look heavy.
• A/B a bright exterior, a dark interior, and a face close-up before you export.
• Export a JPEG/PNG (or a short graded clip from Resolve) and check on a second screen if you have one.

FAQ

Can Lightroom Classic load a free-standing .cube like Photoshop?

Not the same way. Photoshop has Color Lookup → Load 3D LUT for a raw .cube. Lightroom Classic applies looks mainly through Develop profiles in the Profile Browser. Many creators convert a .cube into an .xmp profile with a free converter, then import that profile, or they apply the .cube in Photoshop Color Lookup or Resolve instead.

What is the Profile Browser path in Classic?

In Develop, open the Profile Browser (the four-rectangle icon next to Profile in the Basic panel), then use Browse to explore installed profiles. Custom looks are typically .xmp profiles you import—Classic does not mirror Photoshop's Load 3D LUT dialog for arbitrary .cube files.

Lightroom (cloud) vs Lightroom Classic?

Both products use profiles for creative looks rather than a Photoshop-style Color Lookup .cube loader. Classic is the catalog app with deeper local file control; Lightroom (cloud) syncs to Creative Cloud. The reliable free-standing .cube path on stills remains Photoshop Color Lookup; for timeline video grades, Resolve or Premiere is usually clearer.

Should I apply a creative LUT on log footage?

No. Convert log to Rec.709 first (or use a technical conversion LUT only for that step), then apply a creative Rec.709 look. Filmsilk looks expect Rec.709 input.

Where Filmsilk fits

Filmsilk ships standard 3D .cube looks for Rec.709 that load cleanly wherever your editor accepts .cube (Photoshop Color Lookup, Resolve, Premiere, Final Cut, CapCut, Filmora, VEGAS Pro) and that you can convert to profiles when a Lightroom-only delivery needs one. Try every look on your own frame before you buy. The Collection is $29 one-time; Filmsilk Complete is $39 with Studio export.
