#
# Tone map with gamma function with local adaptation 
# provided by a multi level gaussian blur and "contrast" preprocess.
#

# first load processors
PROCESSORS:
1 = "compressor" # Use simple dynamic range compression.
2 = "coltolum"   # extract brightness channel.
3 = "mlfilter"   # blur the brightness channel.
4 = "contrast"   # blur the brightness channel.


# Now add dependencies
DEPENDENCIES:
1:0 <- 4 # slot 0 is populated by src

2:0 <- 0 # image -> luminance

3:0 <- 2 # luminance -> local adaptation

4:0 <- 0
4:1 <- 3

# Now set parameters
PARAMETERS:

# Set up compressor
1:"compression function" = 2     # gamma
1:"gamma"                = 0.6   # default
1:"discard dark"         = 1     # % of pixels to be set to black.
1:"discard bright"       = 1     # % of pixels to be set to white.
1:"normalise"            = true  # post process brightness to range 0-1
#1:"min luminance"        = 1.0e5  # Use instead of "discard dark"
#1:"max luminance"        = 1.0e-5 # Use instead of "discard bright"

#set up filtering
3:"number of layers" = 6   # number of layers to blend together.
3:"threshold"        = 1   # Edge detection threshold (turn down to stop halos)

# Set up contrast preprocessor
4:"contrast"         = 2   # 

OUTPUT: 1 # 
#OUTPUT 4 # change to this to write output of contrast boost without compress.
