Common options:

-l, --levels=LEVELS

limit number of blending LEVELS to use (1 to 29); negative number of LEVELS decreases maximum; "auto" restores the default automatic maximization

-o, --output=FILE

write output to FILE; default: "a.tif"

-v, --verbose[=LEVEL]

verbosely report progress; repeat to increase verbosity or directly set to LEVEL

--compression=COMPRESSION

set compression of output image to COMPRESSION, where COMPRESSION is: "deflate", "jpeg", "lzw", "none", "packbits", for TIFF files and 0 to 100, or "jpeg", "jpeg-arith" for JPEG files, where "jpeg" and "jpeg-arith" accept a compression level

Advanced options:

--blend-colorspace=COLORSPACE

force COLORSPACE for blending operations; Enfuse uses "CIELUV" for images with ICC-profile and "IDENTITY" for those without and also for all floating-point images; other available blend color spaces are "CIELAB" and "CIECAM"

-c, --ciecam

use CIECAM02 to blend colors; disable with "--no-ciecam"; note that this option will be withdrawn in favor of "--blend-colorspace"

-d, --depth=DEPTH

set the number of bits per channel of the output image, where DEPTH is "8", "16", "32", "r32", or "r64"

-f WIDTHxHEIGHT[+xXOFFSET+yYOFFSET]

manually set the size and position of the output image; useful for cropped and shifted input TIFF images, such as those produced by Nona

-g

associated-alpha hack for Gimp (before version 2) and Cinepaint

-w, --wrap[=MODE]

wrap around image boundary, where MODE is "none", "horizontal", "vertical", or "both"; default: none; without argument the option selects horizontal wrapping

Fusion options:

--exposure-weight=WEIGHT

weight given to well-exposed pixels (0 <= WEIGHT <= 1); default: 1

--saturation-weight=WEIGHT

weight given to highly-saturated pixels (0 <= WEIGHT <= 1); default: 0.2

--contrast-weight=WEIGHT

weight given to pixels in high-contrast neighborhoods (0 <= WEIGHT <= 1); default: 0

--entropy-weight=WEIGHT

weight given to pixels in high entropy neighborhoods (0 <= WEIGHT <= 1); default: 0

--exposure-optimum=OPTIMUM

optimum exposure value, usually the maximum of the weighting function (0 <= OPTIMUM <= 1); default: 0.5

--exposure-width=WIDTH

characteristic width of the weighting function (WIDTH > 0); default: 0.2

--soft-mask

average over all masks; this is the default

--hard-mask

force hard blend masks and no averaging on finest scale; this is especially useful for focus stacks with thin and high contrast features, but leads to increased noise

Expert options:

--save-masks[=SOFT-TEMPLATE[:HARD-TEMPLATE]]

save weight masks in SOFT-TEMPLATE and HARD-TEMPLATE; conversion chars: "%i": mask index, "%n": mask number, "%p": full path, "%d": dirname, "%b": basename, "%f": filename, "%e": extension; lowercase characters refer to input images uppercase to the output image default: "softmask-%n.tif":"hardmask-%n.tif"

--load-masks[=SOFT-TEMPLATE[:HARD-TEMPLATE]]

skip calculation of weight maps and use the ones in the files matching the templates instead. These can be either hard or soft masks. For template syntax see "--save-masks"; default: "softmask-%n.tif":"hardmask-%n.tif"

--fallback-profile=PROFILE-FILE

use the ICC profile from PROFILE-FILE instead of sRGB

--layer-selector=ALGORITHM

set the layer selector ALGORITHM; default: "all-layers"; available algorithms are: "all-layers": select all layers in any image; "first-layer": select only first layer in each (multi-)layer image; "last-layer": select only last layer in each (multi-)layer image; "largest-layer": select largest layer in each (multi-)layer image; "no-layer": do not select any layer from any image;

--parameter=KEY1[=VALUE1][:KEY2[=VALUE2][:...]]

set one or more KEY-VALUE pairs

Expert fusion options:

--exposure-weight-function=WEIGHT-FUNCTION

(1st form) select one of the built-in exposure WEIGHT-FUNCTIONs: "gaussian", "lorentzian", "half-sine", "full-sine", or "bi-square"; default: "gaussian"

--exposure-weight-function=SHARED-OBJECT:SYMBOL[:ARGUMENT[:...]]

(2nd form) load user-defined exposure weight function SYMBOL from SHARED-OBJECT and optionally pass ARGUMENTs

--exposure-cutoff=LOWERCUTOFF[:UPPERCUTOFF[:LOWERPROJECTOR[:UPPERPROJECTOR]]]

LOWERCUTOFF and UPPERCUTOFF are the values below or above of which pixels are weighted with zero weight in exposure weighting; append "%" signs for relative values; default: 0%:100%:anti-value:value

--contrast-window-size=SIZE

set window SIZE for local-contrast analysis (SIZE >= 3); default: 5

--contrast-edge-scale=EDGESCALE[:LCESCALE[:LCEFACTOR]]

set scale on which to look for edges; positive LCESCALE switches on local contrast enhancement by LCEFACTOR (EDGESCALE, LCESCALE, LCEFACTOR >= 0); append "%" to LCESCALE for values relative to EDGESCALE; append "%" to LCEFACTOR for relative value; default: 0:0:0

--contrast-min-curvature=CURVATURE

minimum CURVATURE for an edge to qualify; append "%" for relative values; default: 0

--gray-projector=PROJECTOR

apply gray-scale PROJECTOR in exposure or contrast weighing, where PROJECTOR is one of "anti-value", "average", "l-star", "lightness", "luminance", "pl-star", "value", or "channel-mixer:RED-WEIGHT:GREEN-WEIGHT:BLUE-WEIGHT"; default: "average"

--entropy-window-size=SIZE

set window SIZE for local entropy analysis (SIZE >= 3); default: 3

--entropy-cutoff=LOWERCUTOFF[:UPPERCUTOFF]

LOWERCUTOFF is the value below of which pixels are treated as black and UPPERCUTOFF is the value above of which pixels are treated as white in the entropy weighting; append "%" signs for relative values; default: 0%:100%
