Fujifilm Eterna F-Log LUT

[Brandon Veen]

I’ve been testing the Fujifilm’s Eterna F-Log LUT on some footage and have really been enjoying the look. Due to it being strictly a Log LUT, it doesn’t work with IPP2. The best Legacy combo I’ve found to get closest to the F-Log profile seems to be REDWideGamutRGB and RedLogFilm.

Another LUT I really like is the IPP2 Light Iron LUT that James Miller shared earlier this year and seemed like a good one to compare this to. And boy was I right, in some of the shots the differences are extremely subtle between the two. The two main differences seem to be with how they render cooler tones and warmer tones. Eterna's cool tones have a level of desaturation compared to Light Iron, and you'll find the biggest differences appear in exterior shots. The warmer tones of the Light Iron LUT shows primarily on skin tones, where they'll feel a bit more orange compared to Eterna.

To get the LUT's to match a little bit more in terms of contrast, I used the following changes in the Tone panel in Lumetri:
- Exposure: 0
- Contrast: 64
- Highlights: 26
- Shadows: -6
- Whites: 23
- Blacks: 0

Shot 5 shows the difference between those changes and what the LUT does by itself.

Shot 1: Exterior Test with Vivitar Series 1 90mm

Shot 2: Interior Still with Zeiss CP2 35mm Super Speed

Shot 3: Interior Test with Vivitar Series 1 90mm (+ Macro)

Shot 4: Exterior Test with Vivitar Series 1 90mm
STH, ISO 1000, 5500K, 0 Tint, Medium/Medium IPP2 Settings for LI

Shot 5: Interior Test with Zeiss CP2 35mm Super Speed
STH, ISO 1000, 5000K, 0 Tint, Low/Medium IPP2 Settings for LI

Shot 6: Exterior Frame Grab with Zeiss CP2 35mm Super Speed
STH, ISO 640, 5412K, 1.640 Tint, Medium/Medium IPP2 Settings for LI

Shot 7: Interior Lighting Test with Zeiss CP2 35mm Super Speed
STH, ISO 1000, 3300K, 0 Tint, Low/Hard IPP2 Settings for LI

Test Shots are just different things I had on my portable drive due to being on vacation right now.
I'll likely add more in additional posts if I find they showcase it differently than these, some RGB lighting shots could make a good addition if anybody wants to post some.
That being said, I think a lot of it comes down to intent of the shot for which works better. Panavision and Fujifilm clearly both put a lot of work into their color sciences, and got fairly similar results.
Shot 5 shows this best with everything feeling almost identical between Light Iron, Fuji Eterna, and even to an extent IPP2. The biggest difference seems to be how they handle the blue tone on the silver parts of the camera (in that specific shot).

I'd recommend you try out the LUT on some of your own footage to see if you like it or not, and definitely feel free to post your findings.

Brandon,

I combined the Fujifilm "Eterna" lut with various IPP2 transform Luts into A Hybrid.

Brandon,

Good stuff, Rand! How'd you go about stacking the different LUTs?
Eterna first, and then IPP2 Transform?

 

[rand thompson]

Brandon,


I didn't stack them, I combined them into a "Hybrid" Lut. Each Lut performs a separate operation. The Ipp2 transform performs the first operation(as it should), then the Fuji Eterna Lut last. IPP2 regulates the colors, so adding them or stacking them together won't get you the look you are seeking. That will just blend them together into color mess with IPP2 changing the original intended look of the Fuji Lut. Basically the Ipp2 Lut will make the Fuji Eterna Lut it's Bitch.

Ah, I see. I'm guessing via 3DLutCreator as you highlighted in this thread?

 

[rand thompson]

That's it.

Here's another batch of different shots using both LUTs. The ones to take interest of are Shot 12 and Shot 17.

Shot 12 includes examples of the other 2 Fujifilm LUTS, and a different way to stack them by converting RedLogFilm to FLogGamut and then applying the Eterna LUT. Doing this brings out the vibrancy a bit more.
Shot 17 shows how they handle bright light colored light sources, IPP2 + Light Iron have a fairly gradual change around the bulb where-as Eterna is a bit more harsh of a transition.
Rand's method might make the Eterna have that gradual glow of the others, as I suspect that it's mainly due to IPP2's Highlight Rolloff more than the individual LUTs.

R3D Grabs should be up in the same folder as before for anybody who wants to mess around with them.
I do have some Full Spectrum stuff on this drive I'll go through next and either today or tomorrow will be getting shooting some new stuff of Glacier National Park.

Brandon,


Thanks for all the clips! and I think you are correct about the gradual high roll-off of the hybrid luts.



BTW,

here is what the Fuji eterna + Ipp2 high-medium luts look like in a "non-hybrid" workflow (the Fuji lut placed in a node before the ipp2 hi-med output lut node) in a node tree.

 

[rand thompson]

Brandon,


Ignore all of the examples I posted above, 3DLut Lut crashed a few days ago, thought it was okay. However, from re-examining the Luts, it never combined the Fuji Lut with the IPP2 Luts in the examples I posted above , going through the same procedure I've always used. Let me uninstall and re-install it and see if I can redo the grades over again.

Fuji Eterna + IPP2 "None-Soft" Hybrid LUT

https://www.dropbox.com/s/cg4tnaiogdy0ajp/fuji none soft4.cube?dl=0


Here is the actually Hybrid I made after reinstalling 3DLut creator Pro. I actually had to use 'No' Contrast in order to combine the two Luts at 100% strength for both. The Fuji Lut seems to add more "Red" to the image. You have to find a good "White point" but even then its still too "Red"



Here are some images after using the whitebalance "Eyedropper to find a "White Point" inside the image. No other corrections where made except ISO Changes where stated.

Now for some comparison shots on Full Spectrum footage.

Unfortunately, all I have on this drive is a test of an IR light/ghosthunt.
Didn't encounter any spirits either, but it's always interesting to apply a new LUT to Full Spectrum footage since the results are usually interesting. Shot 21 and 22 I didn't add any additional contrast for the Eterna as they got too dark, and I boosted all three shots +1 stop in Photoshop.

Shot 18: Lit by Streetlamps w/CP2 35mm SS

R3D Grabs are up here aswell.

Thanks for the Hybrid LUT, Rand!
I think based on Fuji's photos it's not exactly their intended look. but I do like it regardless.
It looks to me to be a bit more like a Velvia stock/profile.

Your welcome Brandon! However, I don't think it's exactly ready for Prime Time just yet, HaHaHa!

 

[Sabovic Adis]

These are not FUJI's own LUTs, these are 3rd party emulations.

No WB, transcoded to RWG/Log3G10, graded for brightness in NLE. By eyeballin'. :biggrin:

 

[rand thompson]

Sabovic,

They look great, where did you find these?

 

[Sabovic Adis]

Can't tell, they'll jump me. Don't ask! :rofl:

 

[rand thompson]

Alright then, I wouldn't want you to get jumped, HaHaHaHa. But great looking emulations all the same.

you can use various Lightroom print presets and lut generator to convert them for video usage.
