nikon-curve - generate interpolation data from Nikon tone curves
SYNOPSIS
nikon-curve [ options and input file ]
DESCRIPTION
nikon-curve reads in a Nikon NTC/NCV or NEF file, interprets its tone curve, and writes out a simple ASCII file containing a table of
interpolation values.
OPTIONS
A summary of options is included below.
-h Show summary of options.
-o Specify output file.
-sr Specify sampling resolution. Default is 65536.
-or Specify output resolution. Default is 256.
-nef Specify an NEF file to get tone curve data from.
The -or and -sr options are ignored for NEF files.
NOTE: If a resolution is not specified, a default one will be used. If the -o option is not specified, default files will be used.
EXAMPLE
nikon-curve -sr 65536 -or 256 curveFile -o exportFile

thumbnail - create a TIFF file with thumbnail images
SYNOPSIS
thumbnail [ options ] input.tif output.tif
DESCRIPTION
thumbnail is a program written to show how one might use the SubIFD tag (#330) to store thumbnail images. thumbnail copies a TIFF Class F
facsimile file to the output file and for each image an 8-bit greyscale thumbnail sketch. The output file contains the thumbnail image
with the associated full-resolution page linked below with the SubIFD tag.
By default, thumbnail images are 216 pixels wide by 274 pixels high. Pixels are calculated by sampling and filtering the input image with
each pixel value passed through a contrast curve.
OPTIONS -w Specify the width of thumbnail images in pixels.
-h Specify the height of thumbnail images in pixels.
-c Specify a contrast curve to apply in generating the thumbnail images. By default pixels values are passed through a linear contrast
curve that simply maps the pixel value ranges. Alternative curves are: exp50 for a 50% exponential curve, exp60 for a 60% exponen-
tial curve, exp70 for a 70% exponential curve, exp80 for a 80% exponential curve, exp90 for a 90% exponential curve, exp for a pure
exponential curve, linear for a linear curve.
BUGS
There are no options to control the format of the saved thumbnail images.
