Filmbox Lightroom / PS integration

[cparente10]

I just really want to be able to use filmbox on RAW digital stills. Having integration in Lightroom Classic would be huge for me. This new update with classic stills film stocks is brilliant, but to me it's obvious that many of those stocks would look better on stills format.

I started to look into this few weeks ago and managed to achieve some success in Photoshop. Below workflow does not allow it in LR and not on RAW's. But I managed to use it in PS on variety types of images with success.

Workflow:

• dial in a look in DaVinci Resolve using Filmbox
• export a 3D LUT that expects and returns a Display referred Color Space/Gamma – I experimented with R709G24 and P3D65G22
• using Lattice, convert to a Photography Color Space/Gamma combination of your choice – in my case I made versions for AdobeRGB and PhotoProRGB
• use in PS with some contrast/levels fine tuning underneath to match to your taste

Where I ran into issues:

Ideally I wanted to create 'a technically accurate' scene referred 3D LUT from Resolve, for example DWG In/Out based, and then convert that using Lattice to my photography working color space – PhotoProRGB for an instance.

However I ran into an issue that I wasn't aware of before. Going from Display referred to Scene is not something that is a technical transformation and therefore is not directly supported by Lattice. The workaround is that you export your LUT in DaVinci with Display referred In/Out – R709G24 for example – and that allows Lattice to convert it 'accurately' into PhotoProRGB.

The catch is that the original Display to Scene referred transfom you did in DaVinci was never accurate to begin with, so everything from there on is an estimation. A decently close one though.

Hope it helps.

Also, I'm by far not an expert at color science and Looks building.
More than happy to be corrected and learn more.

We would like to make a solution for raw photography at some point.

Until then we have this experimental tool that helps get raw photos into resolve if you want to use filmbox on them there:

https://andrewfinch.github.io/RawZone2/

It converts most still photo raw formats to LogC4 EXRs which can be used in resolve, (works best in Chrome)

Hi andrew,
Hope you're doing well!
I am a photographer who was looking to find a solution to match my digital files with my analog work. I have used the converter together with my RAW Files and DaVinci. It is working quite well, i am amazed by the quality of the emulation. In the photography world there is nothing that exists on this level.

If you guys ever get around to building a photography solution, I would buy it in a heartbeat! Standalone app I assume would be great, I imagine that the Adobe Lightroom pipeline is not ideal for a tool working at this level. The fact that i am still debating whether the licence is worth it to me, even though I'd have to use a workaround speaks for itself.

For anyone trying to make this work for photos, this was my full workflow:

(converting and importing to Davinci only takes you there 90%, at least in my case using Lightroom)

after exporting from davinci, your photos are in Rec709 Gamma 2.4. To get the image back into Lightroom or whatever photo software, you need to apply a conversion to an Adobe colorspace, Lightroom does not support Rec 709 directly. Can be done easily by

1. convert using raw zone 2
2. do Filmbox magic inside Resolve; export to TIFF or JPEG in Rec709 gamma 2.4
   -> at this stage i imported to LR, but it seems we still have to convert into a LR friendly color space
3. import into Photoshop
4. "assign profile" -> Rec709 Gamma 2.4 (was somehow necessary in my case)
5. convert to profile -> Adobe RGB (1998), for example. sRGB and a few others would also work i imagine.
6. import into LR
