#
# VISUALIZATION METHODS:
#
# Analytical hillshading
# Hillshading from multiple directions
# PCA of hillshading
# Slope gradient
# Simple local relief model
# Sky-View Factor
# Anisotropic Sky-View Factor
# Openness - Positive
# Openness - Negative
# Sky illumination
# Local dominance
# <none>
#
#
# NORMALIZATIONS:
#
# Value - min and max are (linear) cut-off points
# Perc - min and max are 
#
#
# BLEND MODES:
#
# Normal
# Multiply
# Overlay
# Luminosity
# Screen

# SECTION 1: DEFAULT min & max values for visualizations
#
# Recommended histogram stretch (see Ziga's book)
# 
# ... if they're different than overall min and max limits (-1000 to 1000) which is in the 'default_settings' file 
#     -> this is something completely different
