Compositors
Combine Exposures
Combine multiple scene exposures into one high dynamic range image.
Operation pads
This operation exposes the following data pads, defining how it receives, processes, and emits image data:

SVG blend operation exclusion (<code>d = (cA * aB + cB * aA - 2 * cA * cB) + cA * (1 - aB) + cB * (1 - aA)</code>).
Gamma
Math operation gamma, performs the operation per pixel, using either the constant provided in 'value' or the corresponding pixel from the buffer on aux as operands. The result is the evaluation of the expression result = (input >= 0.0f ? powf (input, value) : -powf (-input, value)).
