"Imagine all the images processing in baaatchhh, yeah. You may say I'm dreamer, but now I've got a tool. I hope someday you'll clone it and many operations will become one."

Batch create files with RawTherapee using all possible HaldCLUT presets. While it uses PHP, I'm trying to make it simple for users who don't know this language.

• Windows - just for now; soon it will work with other systems
• RawTherapee 5.x {Download} - ealier versions not tested, but might work
• CLUT files {Download (402 MB!)}
• PHP 7.x {Download for Windows; other OS: use package manager} - 5.x would possibly work, but it's not tested
• .COM and NET extension - available in the default PHP package; script tries to turn it on, if it's not enabled; if it fails, open php.ini from PHP directory and remove semicolon (;) before extension=php_com_dotnet.dll line.
• Photo with RawTherapee PP3 profile with Film simulation turned on (click on the power icon near Film simulation in Colors card); the HaldCLUT directory doesn't have to be set in RawTherapee.

Output for 33 HaldCLUT files (Creative pack only).

Only images were created by script; the collage is made with ImageMagick (command is below); next version will support automatic creation of such all-in-one-with-nice-titles-and-generally-awesome images.

Processing 33 HaldCLUT profiles. JPEG quality: 75% (chroma 4:2:2 (balanced)), fast export disabled.
Files will be saved to: E:\cluttest\out

Path note: script takes care for quoting path, so for c:\foo bar you don't need to write "\"c:\\foo bar\"", but simply "c:\\foo bar". Trailing slash shouldn't matter.

• rawThreapeeBinary ^string - the full path (including file name) to RawTherapee CLI (rawtherapee-cli.exe in Windows)
• inputPhoto ^string - the full path to the photo
• inputProfile ^{nullable string} - input profile; if null, use default profile name (file name + .pp3)
• outputDirectory ^string - directory for output files; if doesn't exist, it will be created
• outputJPEGQuality ^integer - output JPEG quality from 1 to 100
• outputJPEGChroma ^integer - JPEG chroma subsampling - 1 for 4:2:0 (smallest file); 2 for 4:2:2 (balanced); 3 for 4:4:4 (best quality). This setting doesn't affect colors per se, but rather color changes - for files with sharp, colorful edges, it's better to use 3 setting
• outputFastExport ^boolean - true for fast export, i.e. very fast export which bypasses some filters; it should be used only for previews, so in many cases it could be useful here
• clutDirectory ^string - directory with CLUT files. The script uses recursive method, i.e. it will get all files from given directory, but also all files from subdirectories.

• Conditional execution method, which would turn script into OS-independent
• Allow running more than one instance at once (remove constant temporary file name)
• Remove temporary files after processing
• Turn on Film simulation if profile says it's disabled
• Process photos without profiles
• Downsizing of results
• Optional creation of collage instead single files
• Custom name schemas
• Custom strength of filter with ability to provide array of strengths to produce multiple versions
• Allow overwritting files or inform if the image was ignored due to non-overwrite policy
• Move config to separate file
