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

# first load processors
PROCESSORS:
1 = "photographic"
2 = "coltolum" # extract brightness channel.
3 = "mlfilter" # blur the brightness channel.


# Now add dependencies
DEPENDENCIES:
1:0 <- 0 # slot 0 is populated by src
1:1 <- 3 # Take blurred luminance channel.

2:0 <- 0 # image -> luminance

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

# Now set parameters
PARAMETERS:

# Set up compressor
1:"key"           = 0.18
1:"contrast"      = 1.3 # slightly enhanced contrast

#set up filtering
3:"number of layers" = 4   # number of layers to blend together.
3:"threshold"        = 0.3 # Edge detection threshold (turn down to stop halos)

OUTPUT: 1
