Film Simulation Recipes vs Film Emulation in RawTherapee vs Film Simulation Profiles

Interested in Film Simulation Recipes, Film Emulation or Film Simulation Profiles? I made a mini Workshop here, on where to find, how to install and how to use - but above all a lot of links to the largest collection of HaldCluts, Luts, Presets and Profiles you can think of.
Also, this is a work in progress, and will be further supplemented, updated and improved as time goes on.
Do you know any others? please contact me and i will be happy to add them.

When talking about film simulation, there are three options:

- Film simulation recipes are specific settings you can change on camera

Classic Chrome
Dynamic Range: DR200
Highlight: +4
Shadow: -2
Color: +4
Sharpening: +1
Noise Reduction: -3
Grain: Strong
White Balance: Auto, +2 Red, -4 Blue
ISO: Auto up to ISO 6400
Exposure Compensation: -1/3 to -1 (typically)

these can be found :

The simulations listed below are applied in RawTherapee.
When applying a simulation, be it a preset, profile or Lut, always reset the large processing drop down list to neutral - otherwise you will get a combination of different settings, and not the desired result.

Film Emulation / Simulation / HaldCluts or Luts are images in which a certain reference color profile is stored - the color profile can be applied to another image with one click

HaldClut or Lut

Stuart Sowerby has created a set of Fujifilm simulation LUT's for use in RawTherapee and other software, specificaly for Fuji X Trans sensor II and III - I've tested it here also on X Trans I, decide for yourself if you want to use it.    Thanks Stuart !
Note: The term profiles can be misleading, because, in RawTherapee we speak of "profiles" when using .pp3 script files that alter specific settings in RT.

Pat David has a very extensive collection here :   Super Pat !

But also here :

and here :  ( this is my own creation )

or here :

and more from Krzysiu batchHaldCLUT :

How to use them ?

Open RawTherapee -> go to left side - below - preferences icon -> click to open -> in the next screen -> top left - second tab - image processing -> second below -> directories -> HaldClut directory -> go to folder on your computer where your HaldCluts are placed -> select -> open
-> Restart RawTherapee !

Then, open Rawtherapee again -> double click a picture in file browser -> the editor opens

In editor -> third icon on the right side, color -> scroll down to film simulation -> select a film simulation from the drop down list

Activate the film simulation

Or watch our instruction video on YouTube :

In short :
"Go to a website to download Luts.
Save your download in the assigned folder, in this example : adapted camera workshop.
Extract the files in the folder.
When the files have been extracted, the HaldClut folder contains subfolders for color and black and white.
Start RawTherapee and open preferences by clicking the icon on the left side, second icon from below, kind of mixer icon.
In the preferences panel, click on theimage processing tab, top left, second tab from left - then click in directories - on Haldclut directory.
Go to the assigned folder - in this case : adapted camera workshop.
Select the extracted Haldclut folder and click open.
Close the preferences panel and close RawTherapee.
Restart RawTherapee double click on a picture to open in editor.
Click on the right side, top, third icon, color.
Scroll down to film simulation tab, activate by clicking the on/of icon.
Select a film simulation Lut from the drop down list.
Enjoy the applied film simulation ! Thanks for watching the Adapted Camera RawTherapee Film Simulation video."

- Film Simulation Profiles ( presets ) are scripts, text files (.pp3) that can be applied in RawTherapee on any image

Some can be found here : thanks to S├ębastien Guyader and Pat David

GLTR87 - RawTherapee-presets-Fuji-inspired : -> note from author :
"The presets were calibrated with a Sony A7 camera, but they give good results with Canon 5D and Olympus X-Z1 RAW files, and probably others."

My own collection together with HaldClut :

And I found an awesome collection of presets by Stefan Chirila here :  - realy tons of presets, awesome Stefan, thanks !

How to use :

Open Rawtherapee -> -> double click a picture in file browser -> the editor opens -> top right side, fourth icon from right -> click the folder icon - load a profile from file -> in the next screen - select default folder, or go to downloaded folder

select prefered script
