#
# Tone map with the Reinhard photographic operator with local adaptation 
# provided by a bilateral filter and "contrast" preprocess.
#

# first load processors
PROCESSORS:
1 = "photographic"
2 = "coltolum" # extract brightness channel.
3 = "bilateral" # 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:"threshold"        = 0.3   # Edge detection tolerance (turn down to stop halos)
3:"radius"           = 10    # Radius of filter
3:"passes"           = 1     # How many times we filter the data.

# Set up contrast preprocessor
4:"contrast"         = 2.0 # Slight enhancement
