NAME

       enfuse - poor man's HDR

SYNOPSIS

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

DESCRIPTION

       Fuse INPUT images into a single IMAGE.

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

OPTIONS

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

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

       -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

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

       --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

       --layer-selector=ALGORITHM
              set  the layer selector ALGORITHM; default: "all-layers"; available algorithms are:
              "all-layers": select all layers in all images;  "first-layer":  select  only  first
              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

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

       --blend-colorspace=COLORSPACE
              force COLORSPACE for blending operations; Enfuse  uses  "CIECAM"  for  images  with
              ICC-profile  and  "IDENTITY"  for  those  without  and  also for all floating-point
              images;

       -c, --ciecam
              use CIECAM02 to blend colors; disable with "--no-ciecam"

       --fallback-profile=PROFILE-FILE
              use the ICC profile from PROFILE-FILE instead of sRGB

       -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

       -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

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

   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-mu=MEAN
              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

       --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:
       --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

       --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"

       --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

       --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%

       --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"

       Enfuse accepts arguments to any option in uppercase as well as in lowercase letters.

ENVIRONMENT

       TMPDIR The TMPDIR environment variable points to the directory, where to store  ImageCache
              files.  If unset Enfuse uses "/tmp".
