Applying a correction in a certain zone also in
fl
uences the adjacent zones.
The hierarchical levels are selected in a way that the
fi
rst hierarchy level in
fl
uences the entire transition from black to white (0% to
100%) with the main correction done at 25%. Below you can
fi
nd the table of the hierarchy levels and their in
fl
uence zone.

Illustrating GLD correction
Without performing GLD correction, we have a linear response
1
from black to white. This is shown as a green dashed line in the
graph below, where we the horizontal axis represents the signal strength (0% to 100%) and the vertical axis the intensity.

GLD: response curve
The following topics give you an overview of the outcome of the GLD corrections done at different levels.
1. To be fully correct, we will have the gamma response curve instead of a linear response curve. In this explanation, we consider it to be linear however.
