Tonemapping
Reinhard 2005 Tone Mapping
Adapt an image, which may have a high dynamic range, for presentation using a low dynamic range. This is an efficient global operator derived from simple physiological observations, producing luminance within the range 0.0-1.0.
Operation pads
This operation exposes the following data pads, defining how it receives, processes, and emits image data:

Adapt an image, which may have a high dynamic range, for presentation using a low dynamic range. This operator constrains contrasts across multiple spatial frequencies, producing luminance within the range 0.0-1.0.
Border Align
Aligns box of input rectangle with border of compositing target or aux' bounding-box border, if aux pad is not connected the op tries to figure out which bounding box' border applies.
