Step 1: Prepare the LUT File

Format the Memory Card:
- Insert an SD card into your computer.
- Format the card to ensure it's clean and compatible with the ZV-E10 II.
Create the Required Folder Structure:
- On the SD card, create the following folder path:
  - /Private/Sony/PRO/LUT
- Ensure all folder names are case-sensitive and match exactly.
Transfer the LUT File:
- Copy your .cube LUT file (e.g., YourLUT.cube) into the LUT folder you just created.

Step 2: Import the LUT into the Sony ZV-E10 II

Insert the Memory Card:
- Place the SD card back into your ZV-E10 II.
Access the LUT Import Menu:
- Turn on the camera and press the Menu button.
- Navigate to:
  - Exposure/Color (icon: plus-minus)
  - Color/Tone
  - Manage User LUTs
  - Import/Edit
Import the LUT:
- Select an available user slot (User1–User16) to register the LUT.
- Choose the memory card as the source.
- Select the YourLUT.cube file and confirm the import.

Step 3: Apply the LUT to Your Recording

Enable Log Shooting:
- Navigate to:
  - Shooting
  - Image Quality/Rec
  - Log Shooting Settings
- Set Log Shooting to On.
Select the Imported LUT:
- Go to:
  - Exposure/Color
  - Color/Tone
  - Select LUT
- Choose the LUT you imported (e.g., YourLUT).
Monitor with the LUT Applied:
- To view the effect of the LUT on your monitor while shooting:
  - Navigate to:
    - Exposure/Color
    - Color/Tone
    - Display LUT
  - Set Display LUT to On.
- This allows you to see the graded image on the camera's display without affecting the recorded footage.

Note: The Sony ZV-E10 II allows you to import and display custom LUTs for monitoring purposes. However, the LUT is not baked into the recorded footage; the camera records in the selected picture profile (e.g., S-Log3), providing flexibility for color grading in post-production.
