uence of GLD correction
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.
GLD correction on Hierarchy level 1
When a correction is applied to Hierarchy level 1 (blue line), its main in
fl
uence is visible on 25% level. The sum of the adjustment
and the linear transition results in a transition as it is presented by the dash-dotted red line in the graph below.

GLD correction on Hierarchy level 3
Following graph illustrates the same correction done on Hierarchy level 3.
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.
