When you develop a RAW picture in RawTherapee, RT creates a ‘sidecar’ file containing the settings of all the adjustments you made when you processed that RAW file. The sidecar file has the same name as the developed RAW picture, but with a different file extension ( pp3 ). When you re-open the same RAW picture in RT, the sidecar file will be read and all settings/adjustments will be restored.
These “sidecar” files are the same as “processing profiles” in a way that:
– sidecar files contain settings you made resulting an output picture
– profiles are pre programed sidecar files that reproduces adjustments to one or more pictures
In other words, you can use a sidecar file as a base file to make your own profiles.
For instance, make some basic adjustments to a RAW picture – like auto levels, a certain value of sharpening and noise reduction – and then you have two possibility’s :
– save the picture and rename the sidecar file to something you can recognize as the adjustments made, like “basic development.pp3”
– save these adjustments directly as a profile, by clicking the “save current profile” icon, choose an apropriate name like previous example.
This last option has an advantage, if you hold down the Ctrl key while clicking the “save current profile” icon, you can select only the adjusted parameters, resulting in a smaller “partial” profile.
Once you know this, you can create profiles for any kind of adjustment you want to repeat, not only basic development settings – which are certainly very handy – but also adjustments resulting in “special effects” like vintage spepia colored pictures, infra red simulations …
all in one click !
Below you can find the “profile” I used to make this picture,
In Linux as well as in Windows, create an empty file, save as .pp3 file,
and copy/paste the “profile” text into it.
Then in RawTherapee, use the “load a profile from file” button to use it on one of your own pictures.

Again better , hold down the Ctrl key while clicking the “save current profile” icon, choose an apropriate name like previous example,
select only the adjusted parameters, resulting in a smaller “partial” profile.
Lets make a profile for sharpening and denoising
– open picture
– select shapening – set desired parameters,
do the same for denoise
– hold Ctrl key, click “save current profile”
– select sharpening and noise reduction in “parameters to save”
– save to file
– use profile on any picture by clicking “use profile from file” button
You can create as many custom profiles as you like.
