#
# Tone map with the Reinhard photographic operator with local adaptation 
# provided by a multi level gaussian blur and "contrast" preprocess.
#

# first load processors
PROCESSORS:
1 = "photographic"
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:"key"              = 0.18

#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
