NAME

       fulla - Correct lens distortion, vignetting and chromatic aberration

SYNOPSIS

       fulla [options] inputfile(s)

DESCRIPTION

       Apply radial or flat-field vignetting correction as well as geometrical radial distortion and transversal
       chromatic aberration correction.

       fulla can be used to batch correct a large number of files. Radial distortion coefficients can be read
       from a PTLens database (only database version 4.2 is supported).

       Vignetting correction is done the same way as described in the nona script file documentation.
       Vignetting correction can be done based on a flat-field or a radial scaling.

       Vignetting correction by flat-field division:
                               I = I / c,    c = flat-field / mean(flat-field)

       Radial vignetting correction:
                               I = I / c,    c = a + b*r^2 + c*r^4 + d*r^6

       The radial distortion correction is identical to the one implemented by PanoTools:

       r_new = a*r^4 + b*r^3 + c*r^2 + d*r   [1]

       Since transversal chromatic aberrations (TCA) leads to differently scaled objects in the red, green and
       blue channel, it can be corrected by scaling the red and blue channel so that they match the green
       channel. Most applications, like Photoshop or Picture Window Pro offer TCA correction by linear scaling.
       This is equal to varying the d parameter in equation [1].

       See http://hugin.sf.net/tutorials/tca for a method to determine these parameters.

OPTIONS

       -g a:b:c:d
           Radial distortion coefficient for all channels, (a, b, c, d)

       -b a:b:c:d
           Radial  distortion  coefficients  for  blue  channel,  (a, b, c, d). This is applied on top of the -g
           distortion coefficients, use for TCA corr

       -r a:b:c:d
           Radial distortion coefficients for red channel, (a, b, c, d). This  is  applied  on  top  of  the  -g
           distortion coefficients, use for TCA corr

       -p  Try  to read radial distortion coefficients (usually supplied using -g) from the PTLens database. The
           environment variable PTLENS_PROFILE should point to the profile.txt file. Since newer version of  the
           PTLens  database are incompatible with fulla, download the PTLens database from the hugin sourceforge
           website instead: http://www.sf.net/projects/hugin

       -m Canon
           Camera manufacturer, for PTLens database query. EXIF data inside JPEG files is read, if  this  option
           is not given

       -n Camera
           Camera  name,  for  PTLens database query. EXIF data inside JPEG files is read, if this option is not
           given.

       -l Lens
           Lens name, for PTLens database query if not specified, a list of possible lenses is displayed

       -d 50
           Specify focal length in mm, for PTLens database query. EXIF data inside JPEG files is read,  if  this
           option is not given.

       -s  Do not rescale the image to avoid black borders.

       -f filename
           Vignetting correction by flat-field division

               I = I / c,    c = flat-field / mean(flat-field)

       -c a:b:c:d
           Radial vignetting correction by division:

               I = I / c,    c = a + b*r^2 + c*r^4 + d*r^6

       -i value
           Gamma of input data. used for gamma correction before and after flat-field correction

       -t n
           Number of threads that should be used during processing

       -h  Display help summary.

       -o name
           Set  output  filename.  If  more  than  one  image is given, the name will be uses as suffix (default
           suffix: _corr)

       -e value
           Compression of the output files

           For JPEG output: 0-100
           For tiff output: DEFLATE, LZW
       -v  Verbose
