At the default position, no clipping occurs and image data that you push above 1023 on the
internal scopes is preserved and passed through the image processing pipeline to subsequent
nodes. For example, in the following two screenshots, the highlights in the screenshot at top
are blown out raising the gain dramatically in Node 1. In the screenshot at bottom, a subsequent
adjustment in Node 2 lowers the gain and retrieves all the previously clipped values.
The image is clipped using the Gain control in Node 2
The image data that was clipped in Node 1 is retrieved in Node 3 by lowering
the Gain control. This illustrates the preservation of deliberately clipped data.
However, if at any point in a node tree you drag the High Clip slider to the left, even by a single
digit, all image data above the new clipping threshold is discarded from that node forward. In
the following example, the High Clip slider in Node 1 is lowered. The result is that all clipped
image data is discarded. As a result, when Node 2 lowers the gain, there is no image detail left
to retrieve, and all three channels exhibit flattening.
Lowering the High Clip slider in Node 1 forces all image data above the new High Clip threshold
to be irretrievably discarded. Clipped data cannot be brought back by subsequent nodes.
