       enfuse [options] [--output=IMAGE] INPUT...


       Fuse INPUT images into a single IMAGE.

       INPUT... are image filenames or response filenames.  Response filenames
       start with an "@" character.

   Common options:
       -V, --version
              output version information and exit

       -h, --help
              print this help message and exit

       -l, --levels=LEVELS
              number of blending LEVELS to use (1 to 29); negative  number  of
              LEVELS decreases maximum

       -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

       -w, --wrap[=MODE]
              wrap around image boundary,  where  MODE  is  NONE,  HORIZONTAL,
              VERTICAL, or BOTH; default: none;

              set   compression   of   output   image  to  COMPRESSION,  where
              COMPRESSION is: NONE, PACKBITS, LZW, DEFLATE for TIFF files  and
              0 to 100 for JPEG files

   Extended options:
       -b BLOCKSIZE
              image cache BLOCKSIZE in kilobytes; default: 2048KB

       -c     use CIECAM02 to blend colors

       -d, --depth=DEPTH
              set  the  number  of bits per channel of the output image, where
              DEPTH is 8, 16, 32, r32, or r64

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

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

       -m CACHESIZE
              set image CACHESIZE in megabytes; default: 1024MB

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

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

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

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

              center also known as MEAN of Gaussian weighting function  (0  <=
              MEAN <= 1); default: 0.5

       --exposure-sigma=SIGMA standard deviation of Gaussian weighting
              function (SIGMA > 0); default: 0.2

              average over all masks; this is the default

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

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

              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; defaults:

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

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

              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%

              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"
