RawTherapee — An advanced, cross-platform program for developing raw photos.
RawTherapee is an advanced program for developing raw photos and for processing non-raw photos. It is non-destructive, makes use of OpenMP, supports all the cameras supported by dcraw and more, and carries out its calculations in a high precision 32-bit floating point engine.

<Chevrons> indicate parameters you can change.
[Square brackets] mean the parameter is optional.
The pipe symbol | indicates a choice of one or the other.
The dash symbol - denotes a range of possible values from one to the other.
rawtherapee <folder> Start File Browser inside folder.
rawtherapee <file> Start Image Editor with file.
rawtherapee-cli -c <dir>|<files> Convert files in batch using default parameters.
rawtherapee-cli <other options> -c <dir>|<files> Convert files in batch using your own settings.
rawtherapee-cli [-o <output>|-O <output>] [-q] [-a] [-s|-S] [-p <one.pp3> [-p <two.pp3> ...] ] [-d] [ -j[1-100] [-js<1-3>] | [-b<8|16>] [-t[z] | [-n]] ] [-Y] -c <input>
- -c <files> Specify one or more input files.
-c must be the last option.
-o <file>|<dir> Set output file or folder.
Saves output file alongside input file if -o is not specified.
-O <file>|<dir> Set output file or folder and copy pp3 file into it.
Saves output file alongside input file if -O is not specified.
-q Quick-start mode. Does not load cached files to speedup start time.
-a Process all supported image file types when specifying a folder, even those
not currently selected in Preferences > File Browser > Parsed Extensions.
-s Use the existing sidecar file to build the processing parameters,
e.g. for photo.raw there should be a photo.raw.pp3 file in the same folder.
If the sidecar file does not exist, neutral values will be used.
-S Like -s but skip if the sidecar file does not exist.
-p <file.pp3> Specify processing profile to be used for all conversions.
You can specify as many sets of "-p <file.pp3>" options as you like,
each will be built on top of the previous one, as explained below.
-d Use the default raw or non-raw processing profile as set in
Preferences > Image Processing > Default Processing Profile
-j[1-100] Specify output to be JPEG (default, if -t and -n are not set).
Optionally, specify compression 1-100 (default value: 92).
-js<1-3> Specify the JPEG chroma subsampling parameter, where:
1 = Best compression: 2x2, 1x1, 1x1 (4:2:0)
Chroma halved vertically and horizontally.
2 = Balanced (default): 2x1, 1x1, 1x1 (4:2:2)
Chroma halved horizontally.
3 = Best quality: 1x1, 1x1, 1x1 (4:4:4)
No chroma subsampling.
-b<8|16> Specify bit depth per channel (default value: 16 for TIFF, 8 for PNG).
Only applies to TIFF and PNG output, JPEG is always 8.
-t[z] Specify output to be TIFF.
Uncompressed by default, or deflate compression with 'z'.
-n Specify output to be compressed PNG.
Compression is hard-coded to 6.
-Y Overwrite output if present.
- Your pp3 files can be incomplete, RawTherapee will build the final values as follows:
1- A new processing profile is created using neutral values,
2- If the "-d" option is set, the values are overridden by those found in
the default raw or non-raw processing profile.
3- If one or more "-p" options are set, the values are overridden by those
found in these processing profiles.
4- If the "-s" or "-S" options are set, the values are finally overridden by those
found in the sidecar files.
The processing profiles are processed in the order specified on the command line.
