LUMIX Real Time LUT not working? Common fixes

Most Real Time LUT problems trace to one of a few causes. Here is how to spot which one you have and fix it in a minute.

Short answer

Most LUMIX Real Time LUT issues come down to one of these: you are not in the Real Time LUT photo style, the LUT is not loaded onto the camera, the file is the wrong type or size, or you are looking at the RAW rather than the JPEG. Work through the five fixes below in order and one of them will almost always be it.

Still stuck after all five? It is usually a firmware update or an unsupported body. We are happy to help, just get in touch.

1. The Real Time LUT option is greyed out or missing

Cause: firmware, mode, or unsupported body

Real Time LUT is a Photo Style, and on several bodies it arrived through a firmware update. First confirm your camera supports it and is on the latest firmware from Panasonic's support site.

It is also unavailable in some modes. Switch to photo or video recording rather than playback, then open Photo Style and select Real Time LUT. If it is still greyed out, a firmware update is the most likely fix.

2. Your LUT is not showing in the library

Cause: the LUT is not loaded onto the camera yet

A LUT has to be loaded before it appears. Two ways in: add the .cube in the free LUMIX Lab app and tap Transfer to Camera, or copy it to your SD card and Load it under Photo Style, Real Time LUT, LUT Library.

Once loaded it shows up in the list, ready to assign to the LUT button. Full steps are in the install guide. Note that bodies hold a limited number of LUTs at once, so remove old ones if the slots are full.

3. The look is not applying to your shots

Cause: wrong photo style, or you are viewing the RAW

Make sure the Real Time LUT photo style is selected and your look is set. The grade previews live in the viewfinder when it is active.

Then check what you are viewing. Real Time LUT bakes the look into the JPEG; the RAW is saved unprocessed by design, so opening the RAW shows the ungraded file. Shoot JPEG or JPEG+RAW to keep the graded image, and keep the RAW if you want to grade differently later.

4. The .cube file will not load

Cause: wrong format or size

The camera needs a .cube LUT, not the older .vlt VLog view-assist format used by earlier LUMIX bodies. It also has to be a size the camera accepts: use the in-camera friendly 33-point version rather than a large 65-point grading LUT.

Keep the filename simple and, if loading from an SD card, place it in the folder the camera expects. Our looks ship in the correct format for Real Time LUT, so they load without fuss.

5. The colours look off

Cause: opacity, white balance, or base settings

Real Time LUT lets you set the opacity of the look. If it feels too strong or too flat, dial the opacity to taste and save it to a My Photo Style slot.

White balance still matters under the LUT, so set it for the scene. If a look was designed on a specific base, our recommended in-camera settings are listed on each look's page so you can match them exactly.

Real Time LUT troubleshooting FAQ

Why is Real Time LUT greyed out on my LUMIX?

Real Time LUT is a Photo Style, and on some bodies it arrived through a firmware update, so first make sure your camera supports it and is on current firmware. It is also unavailable in certain modes, so switch to photo or video recording rather than playback and select the Real Time LUT photo style. If it is still greyed out, update the firmware from Panasonic's support site.

Why is my LUT not showing in the library?

The LUT has to be loaded onto the camera first. Add the .cube in the free LUMIX Lab app and Transfer to Camera, or copy it to the SD card and Load it under Photo Style, Real Time LUT, LUT Library. Once loaded it appears in the list to assign to the LUT button.

Why is the LUT not applying to my photos?

Select the Real Time LUT photo style and confirm the look is set, then check you are looking at the JPEG. Real Time LUT bakes the look into the JPEG as you shoot; the RAW is saved unprocessed by design, so a RAW viewer shows the ungraded file. Shoot JPEG or JPEG+RAW to keep the graded image.

Why will my .cube file not load on LUMIX?

The camera needs a .cube LUT, not the older .vlt VLog view-assist format, and it must be a size the body accepts. Use the in-camera friendly 33-point version rather than a large 65-point grading LUT, keep the filename simple, and place it in the correct folder if loading from an SD card. Our looks ship in the right format for Real Time LUT.

Which LUMIX cameras support Real Time LUT?

The S9, S5II, S5IIX, S1II, S1RII, G9II, GH7 and the new L10. Some received it through a firmware update, so check you are on the latest firmware if the feature is missing.
