Inputs (10)

Name	Type	Default	Description
file_path	STRING		Path to a camera RAW file (.nef .cr2 .cr3 .raf .arw .dng). Relative paths are resolved from ComfyUI's input folder.
undistortopt	BOOLEAN	true	Lensfun geometry correction from the EXIF lens model ([raw-lens] extra). Skipped with a report line when no profile matches (common for Fuji X — in-body corrections).
half_sizeopt	BOOLEAN	false	Half-resolution demosaic for fast iteration on 36-100MP files.
white_balanceopt	COMBO	camera	2 options: camera, auto
exposure_evopt	FLOAT	0.0-6–6	—
write_exropt	BOOLEAN	true	Write a scene-linear EXR sidecar and reference it in plate_ref (needs the OpenImageIO [oiio] extra; OpenCV is not used). On failure the plate_ref degrades to proxy.
output_diropt	STRING	atlas_exports/raw_plates	—
colorspaceopt	STRING	Linear Rec.709 (sRGB)	Colorspace TAG for the sidecar. rawpy's linear output has sRGB/Rec.709 primaries — NOT ACEScg; convert downstream via OCIO. Retag only if your config names it differently.
headroomopt	FLOAT	6.000.25–64	Highlight headroom factor, applied to the scene-linear EXR (display/solve tensor unaffected). Matches rawtoaces' --headroom default of 6.0: sensor clip lands ~6x above 1.0 so diffuse white sits near 1.0, which is what ACES scene-linear expects. 1.0 = raw clip-normalised (pre-2026-08 behaviour, reads ~2.6 stops dark under an ACES view transform).
projectopt	ATLAS_PROJECT		Optional delivery project from AtlasProject — routes the developed EXR into the project tree's plates/ lane and supersedes output_dir.
